**** BEGIN LOGGING AT Tue Nov 20 02:59:57 2012
Nov 20 03:39:50 <ptl> hello
Nov 20 03:40:08 <ptl> is there a mailing list or forum where the ubuntu on nexus 7 is discussed?
Nov 20 03:40:28 <ptl> could not find that in the wiki
Nov 20 03:51:59 <twb> there's always xda forum
Nov 20 07:18:09 <[mbm]> twb: the single xda thread is somewhat annoying to follow
Nov 20 07:28:33 <ynezz> forums should be illegal :p
Nov 20 07:35:29 <[mbm]> I get annoyed by these single thread things that go on for 20+ pages
Nov 20 07:51:46 <dholbach> good morning
Nov 20 10:04:40 <day> is there a site regarding nexus7 - ubuntu hardware support? what is fully supporter what not and so on?
Nov 20 10:04:45 <day> supported*
Nov 20 10:05:03 <ogra_> there is the buglist
Nov 20 10:05:15 <ogra_> somewhere linked under the wikipage
Nov 20 10:05:49 <day> the known issues?
Nov 20 10:06:10 <day> wasnt sure how up2date that is
Nov 20 10:06:35 <ogra_> many of the bugs are touched daily by our QA guys
Nov 20 10:06:53 <ogra_> or at least they look over it very regulary
Nov 20 10:07:38 <ogra_> essentially we only have wlan and partitally bluetooth working
Nov 20 10:08:02 <ogra_> most if not all the rest is still waiting for someone to adopt ;)
Nov 20 10:08:36 <ogra_> i think soimeone works on the gyro sensor stuff, but i'm not 100% sure
Nov 20 10:09:11 <day> ogra_: gyro and gps shouldnt be toooo complicated. its not like you communicate with an unknown entity there
Nov 20 10:09:31 <day> ogra_: anyways thanks. i will give it a shot :)
Nov 20 10:09:35 <ogra_> well, gyro is complicated because there is absolutely nothing in userspace for it atm
Nov 20 10:10:01 <ogra_> even if you get the device to work, there is no API or something in X so it needs some upstream development
Nov 20 10:10:28 <ogra_> (some lib that interconnects xrandr, the sensor and xinit rotation processing)
Nov 20 10:10:38 <ptl> so, there is no canonical-sponsored mailing list for Ubuntu on Nexus 7?
Nov 20 10:10:45 <ogra_> s/xinit/xinput/ (sorry)
Nov 20 10:10:58 <day> ogra_: hmm makes sense
Nov 20 10:11:01 <ogra_> ptl, we use the normal ubuntu lists
Nov 20 10:11:22 <ogra_> ubuntu-devel/ubuntu-devel-discuss for development discussion
Nov 20 10:12:50 <ogra_> xnox, why do i suddenly get lvm2 andf kpartx in my arm initrds ? i cant remember it being that way with ac100 ubuntu images in precise, did we add new deps ?
Nov 20 10:12:56 <ptl> ogra_: but the amount of unrelated stuff / noite there might be unimaginable :-/
Nov 20 10:13:09 <ptl> *noise
Nov 20 10:13:15 <xnox> ogra_: you shouldn't.
Nov 20 10:13:17 <ogra_> ptl, up to now no bigger noise showed up :)
Nov 20 10:13:29 <day> ogra_: i just realized ur a pretty active linux/ubuntu dev. thanks for all your work :)
Nov 20 10:13:33 <ogra_> xnox, well, on the newly built images that is
Nov 20 10:13:43 <xnox> ogra_: unless something is pulling lvm2 in.....
Nov 20 10:13:59 <ogra_> day, heh, thanks for using it :)
Nov 20 10:14:09 * xnox will look.
Nov 20 10:14:18 <ogra_> xnox, yeah, thats what i think, funnily it doesnt happen on lubuntu ac100 images
Nov 20 10:14:26 <xnox> lolz.
Nov 20 10:14:31 <ogra_> which build with --no-install-recommends though
Nov 20 10:14:45 <ogra_> so i assume a new recommends somewhere in ubiquity
Nov 20 10:14:51 <xnox> ogra_: so which images are you seeing this with? the rarings or quantals lubuntu ac100?
Nov 20 10:15:17 <ogra_> in any case i end up with a 2.4M initrd, thats likely to big (or at least at the edge for becoming unbootable)
Nov 20 10:15:38 <ogra_> the raring nexus7 testbuilds
Nov 20 10:15:49 <lilstevie> day, tbh the GPS isn't 100% straight forward either
Nov 20 10:16:30 <day> lilstevie: why is that?
Nov 20 10:16:52 <lilstevie> day, get the GPS chip to output NMEA over the UART :)
Nov 20 10:17:38 <day> lilstevie: that doesnt sound to complicated. its a standard amateur 8-bit uC hobby project
Nov 20 10:17:53 <lilstevie> day, once you get that it will be straight forward, but getting it to turn on correctly isn't
Nov 20 10:18:13 <lilstevie> day, you are meant to be able to just wiggle a gpio and it comes to life
Nov 20 10:18:14 <lilstevie> :p
Nov 20 10:18:28 <ogra_> xnox, http://people.canonical.com/~ubuntu-archive/livefs-build-logs/raring/ubuntu-nexus7/20121119.5/livecd-20121119.5-armhf.out the update-initramfs call at the end runs with -v
Nov 20 10:18:37 <day> lilstevie: you are meant to be able to just wiggle a gpio. is that hard via linux? :p
Nov 20 10:18:42 <ogra_> (ignore the abootimg noise)
Nov 20 10:18:59 <lilstevie> day, no, wiggling the gpio is just ineffective
Nov 20 10:19:13 <lilstevie> aka missing something
Nov 20 10:19:26 <ogra_> xnox, ac100 for comparison http://people.canonical.com/~ubuntu-archive/livefs-build-logs/raring/lubuntu-ac100/20121119/livecd-20121119-armhf.out
Nov 20 10:19:54 <lilstevie> day, someone with enough determination could probably get it going though
Nov 20 10:20:01 <day> lilstevie: well how else do you want it to do? the gps chip is wired to some pin which has to do it :/
Nov 20 10:20:05 <xnox> ogra_: yeah it's funny =)
Nov 20 10:20:23 * ogra_ sighs about all that arabic spam 
Nov 20 10:20:31 <lilstevie> day, you are missing the point, following the gps enable isn't enough
Nov 20 10:20:49 <lilstevie> day, so spend some time following it being enabled in android :p
Nov 20 10:21:03 <xnox> ogra_: so oem-config is installed, that depends on ubiquity, which in turn recommends lvm2 & dmraid
Nov 20 10:21:23 <ogra_> right, so as i assumed, its recommends
Nov 20 10:21:27 <xnox> ogra_: but you say you install with --no-install-recommends
Nov 20 10:21:35 <ogra_> not on nexus
Nov 20 10:21:39 <xnox> ah.
Nov 20 10:21:43 <ogra_> lubuntu-desktop enforces it
Nov 20 10:21:56 <ogra_> nexus uses ubuntu, ac100 lubuntu
Nov 20 10:22:20 <lilstevie> day, point is straight forward would be sysfs write and away it runs, not so straight forward is tracking down the bit that is missing
Nov 20 10:22:21 <ogra_> well, i guess i can add a hack that removes both packages before building the initrd
Nov 20 10:22:26 <day> lilstevie: day, so spend some time following it being enabled in android :p -> ur talking about the reengineering process?
Nov 20 10:22:29 <ogra_> its just ugly :(
Nov 20 10:22:35 <xnox> ogra_: can you work around it in the seeds, or shall I demote lvm2 to suggests?
Nov 20 10:22:52 <xnox> ogra_: can you not blacklist it?
Nov 20 10:22:59 <lilstevie> day, of course, how else would you expect to do it
Nov 20 10:23:13 <xnox> ogra_: to be honest it's wrong to install those, simply to get oem-config.
Nov 20 10:23:24 <ogra_> we dont have any blacklist, the only way i coudl do that would be in the seeds ... but thats arch and not subarch specific
Nov 20 10:23:39 <ogra_> which would mean no lvm2 seeded on arm servers either
Nov 20 10:23:40 <day> lilstevie: i dont know, maybe take a look on the datasheet? but i guess thats no available :P
Nov 20 10:23:48 <ogra_> you dont really want that :)
Nov 20 10:23:52 <xnox> ogra_: split ubiquity into ubiquity & ubiquity-partman-deps ?
Nov 20 10:24:01 <lilstevie> ogra_, which would also hurt me cause I use lvm2 on the tf201
Nov 20 10:24:08 <ogra_> hmm, that might work
Nov 20 10:24:34 <lilstevie> day, I'm saying YOU do it :p I'm not going to, not high enough of a priority
Nov 20 10:24:40 <ogra_> we really want to keep lvm on systems that run a partitioner
Nov 20 10:24:44 <xnox> ogra_: but then we would have to carefully install ubiquity-partman-deps on the images that have installer.
Nov 20 10:25:27 <lilstevie> xnox, at the moment we are seeding with oem-config but use lvm
Nov 20 10:25:28 <xnox> horum.
Nov 20 10:25:34 <ogra_> yeah, i should probably just add some apt-get purge code to the build scripts
Nov 20 10:25:48 <day> lilstevie: if i had a clue of driver programming under linux i would. :P
Nov 20 10:26:16 <xnox> ogra_: well we can add more black magic to the initramfs hook in the lvm2 package to not copy itself as eagerly as it currently does.
Nov 20 10:26:18 <lilstevie> xnox, but adding lvm to the seeds I guess isn't a problem
Nov 20 10:26:27 * ogra_ prays that his abootimg quoting is now right 
Nov 20 10:26:56 <ogra_> xnox, i'm not sure the lvm2 bits are the biggest ones, there is also kpartx
Nov 20 10:28:08 <xnox> ogra_: wait you _do_ use lvm2 on nexus7 images?
Nov 20 10:28:13 <xnox> lilstevie: ^
Nov 20 10:28:18 <ogra_> xnox, no
Nov 20 10:28:27 <ogra_> lilstevie talks about the asus transformer
Nov 20 10:28:32 <xnox> ah.... =)
Nov 20 10:28:43 <lilstevie> xnox, not nexus 7 tf201, but we have been following the same method to generate images
Nov 20 10:29:14 <ogra_> hmm, i wonder how much dropping parted from the initrd would gain me
Nov 20 10:29:38 <ogra_> we only need it on the ac100, the ac100-tarball-installer could just not pull it in if we build for xenus
Nov 20 10:29:42 <ogra_> *nexus
Nov 20 10:31:00 <ptl> I modified a setting in nvidia-tegra x11.org template and now it does not start X. How can I recover?
Nov 20 10:31:10 <ptl> in Ubuntu Nexus7
Nov 20 10:31:32 <ogra_> did you install openssh-server ?
Nov 20 10:31:38 <ptl> yes
Nov 20 10:31:41 <ogra_> so you can get in via the network
Nov 20 10:31:58 <ptl> how? it needs the graphical login to start, isn't it?
Nov 20 10:32:06 <ogra_> no
Nov 20 10:32:13 <ogra_> you should be able to just ssh in
Nov 20 10:32:14 <ptl> er... no it doesn't :P
Nov 20 10:32:15 <ptl> sorry
Nov 20 10:33:38 <ptl> if I install gpsd on Ubuntu Nexus 7 and some gps program, will I be able to use it as a GPS?
Nov 20 10:34:19 <ogra_> dunno, try it (and document what you did to make it work once you have it working)
Nov 20 10:35:44 <ptl> k thx :)
Nov 20 11:28:13 <ogra_> oh, wow, the HDMI multi monitor mode of the chromebook is impressive, unity automatically picks it up and adds four new workspaces
Nov 20 11:33:03 <lilstevie> nice
Nov 20 11:38:31 <janimo> ptl, Android uses some binary libraries on the Nexus7 for GPS. So you may not be successful unless you figure out how to use them, or find free alternatives
Nov 20 11:38:42 <janimo> but there needs to be some hw specific support somewhere
Nov 20 11:39:01 <janimo> I don't know anything about GPS though, besides what i wrote above :)
Nov 20 13:29:27 <ptl> anyone knows a good CuBox kernel that has the device mapper compiled in?
Nov 20 13:30:10 <ptl> janimo: oh, thanks for the info :-/ I thought GPS was something more open than that though
Nov 20 13:30:18 <ptl> I would expect that from, say, GPRS stack
Nov 20 13:31:39 <janimo> ptl, https://developers.google.com/android/nexus/drivers#grouperjop40c has GPS blobs in the same zip as wifi and BT
Nov 20 13:32:31 <janimo> that said it may not be hard to integrate with gpsd I have no idea how the GPS stack looks like :)
Nov 20 13:32:41 <ptl> <- tired by all this closed-minded approach of hardware manufacturers
Nov 20 13:32:51 <janimo> cyphermox in ubuntu-devel has the task this cycle to look into GPS among other things
Nov 20 13:38:24 * janimo wonders whether to ust include most nexus7 blobs in the raring nexus firmware package to ease tinkering
Nov 20 13:38:48 <ogra-cb> ++ if legal allows
Nov 20 13:41:52 <ptl> what's '-cb', ogra?
Nov 20 13:42:25 <ogra-cb> chromebook
Nov 20 13:43:06 <ptl> dang, I thought it would be CuBox :D
Nov 20 13:43:25 <ogra-cb> nah, i dont touch cortex-a8 anymore
Nov 20 13:44:49 <ptl> it is cortex a9, isn't it?M
Nov 20 13:45:02 <ogra-cb> ah, might be
Nov 20 14:18:21 <lilstevie> isn't the CuBox a Marvell Armada510
Nov 20 14:23:49 <ptl> lilstevie: yes

Nov 20 14:52:00 <ogra-cb> \o/
Nov 20 14:52:28 <dholbach> yoohoo
Nov 20 14:52:44 <ogra-cb> still to big, but at least it should boot now
Nov 20 14:54:20 <Tassadar> wau
Nov 20 14:55:01 <Tassadar> well, what exactly livecd means, i mean, is it normal image or..?
Nov 20 14:55:38 <ogra-cb> thats the raring (13.04) image i'm working on
Nov 20 14:58:05 <Tassadar> by the way, is abootimg part of this whole ubuntu-supports-android-devices thing?
Nov 20 14:58:40 <ogra-cb> well, we currently use it to creatte or modify boot image parameters
Nov 20 14:59:09 <Tassadar> it does not fill the id[] part of the boot image's header
Nov 20 14:59:36 <ogra-cb> is that important for anything ?
Nov 20 14:59:56 <ogra-cb> i havent seen probs caused by rgar neither on the ac100 nor on the nexus7
Nov 20 15:00:13 <Tassadar> not really, just explaining why I care
Nov 20 15:00:19 <ogra-cb> s/rgar/that/
Nov 20 15:01:57 <lilstevie> Tassadar, little more explanation please :)
Nov 20 15:02:10 <lilstevie> doesn't cause issues with tf101/tf201 either fwiw
Nov 20 15:03:35 <Tassadar> Well, I use the id array to distinguish boot images when multi-booting, I simply noticed that default ubuntu's boot.img has all 0's, which is not correct
Nov 20 15:04:06 <Tassadar> the id is important only so that you can say that boot images are different only by reading header
Nov 20 15:04:25 <Tassadar> and I thought tha abootimg was created as part of ubuntu
Nov 20 15:07:15 <ogra-cb> t was created as part of the ac100 netbook being enabled for linux
Nov 20 15:07:35 <ogra-cb> ubuntu was simply the first ditro to run on it :)
Nov 20 15:08:47 <ogra-cb> and the tool is helpful enough to be used with all existing android bootimages
Nov 20 15:09:06 <ogra-cb> i assume there is a way to set the id field with something
Nov 20 15:09:13 <Tassadar> no, not really
Nov 20 15:09:42 <Tassadar> I'm gonna go find source repository and maybe send a patch or something
Nov 20 15:10:11 <ogra-cb> abootimg -u <bootimg> -c "id=foo"
Nov 20 15:10:20 <ogra-cb> something like that doesnt work ?
Nov 20 15:10:45 <Tassadar> I searched the code, and it just sets it to zero I think, I'll check again
Nov 20 15:12:56 <ogra-cb> well, i'm pretty sure gilles is open to patches that fix this
Nov 20 15:15:02 <Tassadar> yeah, just calloc(), which sets everything to 0, and then it is not changed anywhere
Nov 20 15:15:42 <Tassadar> hmm, gitorious can't do forks, can it? Oh well
Nov 20 15:16:50 <Tassadar> Ah, it just calls it "clone", okay
Nov 20 15:53:33 <ogra-cb> sigh, if i only had named the image right
Nov 20 16:03:54 <vanhoof> ogra-cb: happy to test as well if you'd like :)
Nov 20 16:04:17 <ogra-cb> nothing to test yet, but i will shout
Nov 20 16:04:33 <vanhoof> ogra-cb: cool
Nov 20 16:05:02 <vanhoof> ogra-cb: did an upgrade friday to R with only a few issues :)
Nov 20 16:05:22 <ogra-cb> debian-cd doesnt handle it if its called .img, i had to rename it .... which means a change in livecd-rootfs ... uploading it ... waiting for the publisher to promote it, waiting for the local builder mirror to pick it up and then a 90min build
Nov 20 16:05:55 <ogra-cb> so expect something from my next attempt in 3h or so :)
Nov 20 16:31:44 <vanhoof> ogra-cb: asked that reporter for more info on where UDA is actually mapped to
Nov 20 16:31:47 <vanhoof> ogra-cb: https://bugs.launchpad.net/ubuntu-nexus7/+bug/1079729/comments/28
Nov 20 16:31:47 <ubot2> Launchpad bug 1079729 in ubuntu-nexus7 "Ubuntu uninstallable on 32GB 3G Nexus 7" [High,Invalid]
Nov 20 16:32:14 <vanhoof> ogra-cb: quite odd, even though his value is slightly less than mine here, should still fit within the 27gb boundry
Nov 20 16:32:33 <ogra-cb> vanhoof, yeah, i was wanting to do that but then my build finished and distracted me
Nov 20 16:32:35 <vanhoof> ogra-cb: one thing I noticed after forcing the OTA update to 4.2, is I now have a /sdcard/0/
Nov 20 16:32:41 <vanhoof> but im not sure how that would impact things
Nov 20 16:33:02 <ogra-cb> well, it will unlikely repartition the device
Nov 20 16:33:27 <ogra-cb> but there will likely be devices with different MMCs
Nov 20 16:33:38 <Tassadar> 0/ is just a folder
Nov 20 16:33:45 <ogra-cb> which will require different partitioning
Nov 20 16:34:13 <vanhoof> Tassadar: yeah just the only thing I noticed that is different after moving to 4.2 from 4.1.2, not sure its related at all
Nov 20 16:34:18 <ogra-cb> especially since android solely works by name the device can be anything
Nov 20 16:35:21 <Tassadar> hmm, that means I should use only partition names too
Nov 20 16:35:24 * Tassadar takes a note
Nov 20 16:35:57 <ogra-cb> no, you want labels
Nov 20 16:36:51 <Tassadar> I mean the "/dev/block/platform/sdhci-tegra.3/by-name/APP"-like paths
Nov 20 16:37:21 <Tassadar> so yeah, labels, wrong term, sorry)
Nov 20 16:47:40 <hrw> Tassadar: android 4.2 added multiuser handling
Nov 20 16:47:51 <hrw> Tassadar: that's why you have /0/ in many places
Nov 20 16:47:59 <hrw> Tassadar: check /data/ as well
Nov 20 16:49:30 <Tassadar> yeah, I've noticed
Nov 20 16:51:07 <hrw> my archos tablet will probably break before 4.2 will be available for it
Nov 20 16:51:29 <prpplague> hehe
Nov 20 16:52:15 <hrw> omap4430 suxx
Nov 20 16:52:42 <Tassadar> well, I've downgraded back to 4.1 anyway
Nov 20 16:52:56 <Tassadar> they removed tablet UI, and the whole system does not feel as snappy as before
Nov 20 16:52:58 <Tassadar> :/
Nov 20 16:57:04 <hrw> I will think 3 times before buying next tablet. 1st 'which one' 2,3 'are you mad?' ;D
Nov 20 17:05:09 <vanhoof> ogra-cb: well there we go
Nov 20 17:05:10 <vanhoof> lrwxrwxrwx root root 2012-11-20 13:48 UDA -> /dev/block/mmcblk0p10
Nov 20 17:05:37 <ogra-cb> heh
Nov 20 17:05:46 <ogra-cb> as i thought
Nov 20 17:07:34 <ogra-cb> thats pretty bad
Nov 20 17:07:53 <ogra-cb> it will add one additional reboot to the install process
Nov 20 17:08:10 <ogra-cb> hmm
Nov 20 17:08:33 <Tassadar> chm
Nov 20 17:10:40 <vanhoof> ogra-cb: yup, RDO was added, which bumped UDA to p10
Nov 20 17:11:14 <Tassadar> it is the 3g N7?
Nov 20 17:11:21 <Tassadar> *is it...ya know
Nov 20 17:11:50 <ogra-cb> so i think we need to go with UUIDs
Nov 20 17:13:10 <vanhoof> Tassadar: yup
Nov 20 17:13:24 <ogra-cb> *if* the fastboot ext4 allows us to update it at least
Nov 20 17:14:17 <Tassadar> at least the boot image is the same
Nov 20 17:14:58 <ogra-cb> yes, thats the issue, while we can use that for initial booting, the uuid should be unique
Nov 20 17:15:04 <ogra-cb> so we need to update it
Nov 20 17:16:19 <Tassadar> can't you use the "/dev/block/platform/sdhci-tegra.3/by-name/APP" path?
Nov 20 17:18:35 <ogra-cb> no
Nov 20 17:18:51 <ogra-cb> its non existent without android kernel
Nov 20 17:19:20 <ogra-cb> ubuntu@nexus7-roccos:~$ sudo blkid /dev/mmcblk0p9

Nov 20 17:20:10 <ogra-cb> ah, well, seems to work
Nov 20 17:20:20 <ogra-cb> lets see if the fs is still working after a reboot
Nov 20 17:20:39 <ogra-cb> usually it starts eating itself as soon as i used any filesystem tools on it
Nov 20 17:21:13 <Tassadar> oh, I see, ueventd creates that path
Nov 20 17:21:38 <ogra-cb> yay, that works fine
Nov 20 17:26:07 <ogra-cb> so we just need to store the image UUID somewhere the initrd can read it
Nov 20 17:26:18 <ogra-cb> on first boot
Nov 20 17:27:03 <ogra-cb> and after extracting the tarball we bump to a new uuid and set a proper root= cmdline pointing to it
Nov 20 17:29:02 <ogra-cb> but well, first let me get images at all
Nov 20 17:29:28 <ogra-cb> vanhoof, you can turn the bug into an ac100-tarball-installer one
Nov 20 17:30:00 <ogra-cb> thats the place where i'll fis it for raring
Nov 20 17:30:04 <ogra-cb> *fix
Nov 20 18:16:27 <Tassadar> ogra-cb: hmm, you think it's okay to find /data by parsing /proc/partitions and looking for the biggest one?
Nov 20 18:16:52 <ogra-cb> huh ?
Nov 20 18:17:29 <ogra-cb> why would i search for the biggest partition ?
Nov 20 18:17:44 <Tassadar> I mean, when I do the multi-boot, I need /data partition, and I can't really use UUID
Nov 20 18:17:51 <ogra-cb> i just want to find the one the tarball lives in
Nov 20 18:19:07 <ogra-cb> fastboot flashes to userdata, it knows what the biggest one is etc
Nov 20 18:19:30 <ogra-cb> the image we flash has (as every ext4 filesystem) a uuid
Nov 20 18:19:50 <ogra-cb> so our installer bootimg will have that uuid in its root= arg
Nov 20 18:20:28 <ogra-cb> to make the uuid actually unique we update the uuid on the fs and in the bootloader after untarring
Nov 20 18:20:55 <ogra-cb> its not different to what we do now just that the uuid gets updated
Nov 20 18:21:22 <ogra-cb> and that we dont depend on device names
Nov 20 18:21:42 <Tassadar> yes, I am lookin for a way to find data partition during boot, which would work on both android and ubuntu, and all the Nexus models
Nov 20 18:22:31 <RaYmAn> you could read the nvidia partition table and find the UDA partition number, then convert it to the GPT partition number :P
Nov 20 18:22:56 <vanhoof> ogra-cb: yup
Nov 20 18:22:58 * ogra-cb will seriously stick to ubuntu defaults
Nov 20 18:23:12 <ogra-cb> which means root=UUID=...
Nov 20 18:23:12 <vanhoof> ogra-cb: will do, was just looking at tarball-installer and thinking about how to fix :D
Nov 20 18:23:34 <Tassadar> okay, i will use the dumb "find biggest" method, since I can't think of a scenario in which it will fail :)
Nov 20 18:30:23 <mfisch> cwayne: I'm going to try that gsettings switch for gksu in our defaults
Nov 20 18:30:33 <mfisch> cwayne: but I Think people will need to reinstall to get the setting
Nov 20 18:30:55 <cwayne> mfisch: reinstall that package?
Nov 20 18:30:58 <cwayne> or reinstall the system
Nov 20 18:31:08 <mfisch> cwayne: system, because it's a settings override
Nov 20 18:31:20 <mfisch> creating a new user also works, that's how I'll test it
Nov 20 18:31:56 <cwayne> mfisch: ack
Nov 20 18:33:16 <mfisch> oh this is gconf, not gsettings
Nov 20 18:34:36 <vanhoof> ogra-cb: fixed up that bug and added a brief description
Nov 20 18:34:51 <ogra-cb> great
Nov 20 18:35:04 <vanhoof> ogra-cb: lmk if that works for you
Nov 20 18:36:18 <ogra-cb> sounds good, yep
Nov 20 18:58:35 <ogra-cb> vanhoof, for the tarball-installer in case you want to fix it for quantal, pull abootimg into the initrd using the hook script, detect if you are on a 3G model on boot, in that case use abootimg to update the cmdline in mmcblk0p2 and reboot
Nov 20 19:00:29 <vanhoof> ogra-cb: any sane way to detect, short of polling the partitions, assuming we only have bb at that point right?
Nov 20 19:01:23 <ogra-cb> you have proc ;)
Nov 20 19:01:30 <vanhoof> fair enough :)
Nov 20 19:01:43 <ogra-cb> and dev indeed
Nov 20 19:02:04 <ogra-cb> what Tassadar said above should work for a hack
Nov 20 19:02:39 <ogra-cb> cat /proc/partitions .... sort ... head -1
Nov 20 19:02:44 <ogra-cb> or some such
Nov 20 19:03:01 <ogra-cb> (likely some more processing needed)
Nov 20 19:11:01 <vanhoof> ogra-cb: *curses*
Nov 20 19:11:05 <vanhoof> dd
Nov 20 19:11:08 <vanhoof> [...]
Nov 20 19:11:11 <vanhoof> <no label>
Nov 20 19:11:14 <vanhoof> [...]
Nov 20 19:11:15 <vanhoof> ;)
Nov 20 19:15:04 <ogra-cb> vanhoof, cat /proc/partitions| grep $(cat /proc/partitions |grep mmcblk0p|awk '{print $3}'|sort -gr|head -1)
Nov 20 19:15:40 <ogra-cb> thats good enough for a hack
Nov 20 19:15:41 <vanhoof> ogra-cb: right, I was attempting to be clever w/ dd to parse any label or evidence of UDA :)
Nov 20 19:16:04 <Tassadar> and it indeed works
Nov 20 19:16:34 <RaYmAn> vanhoof: did you look at uhm, /dev/block/by-name/ or similar?
Nov 20 19:16:37 <ogra-cb> you can likely somehow get it out of the GPT
Nov 20 19:16:57 <Tassadar> well, the 50-line C function equivalent to that one bash line works :D
Nov 20 19:19:51 <vanhoof> RaYmAn: dd'ing off of the raw device itself (p9) and inspecting w/ strings to see what I can find
Nov 20 19:19:58 <vanhoof> RaYmAn: more so curious if anything :)
Nov 20 19:20:34 <Tassadar> RaYmAn: these do not exist when using ubuntu kernel
Nov 20 19:20:54 <ogra-cb> grep $(grep mmcblk0p /proc/partitions |awk '{print $3}'|sort -gr|head -1) /proc/partitions
Nov 20 19:21:06 <ogra-cb> whorter and less cat'ing :)
Nov 20 19:21:13 <ogra-cb> *shorter
Nov 20 19:22:05 <RaYmAn> Tassadar: hmm..well, android kernel must be getting it from somewhere.
Nov 20 19:22:40 <ogra-cb> from the GPT i guess
Nov 20 19:22:40 <Tassadar> it certainly must, but I don't wanna change ubuntu's kernel
Nov 20 19:22:59 <Tassadar> wait, I think I know..
Nov 20 19:23:53 <Tassadar> hm, no I dont
Nov 20 19:24:19 <RaYmAn> those partitions names are a bit of a mess across asus transformer devices. Some of them have wrong names by default , which may or may not get fixed during random OTA flashes. So don't expect that kind of detection to work outside of N7
Nov 20 19:24:26 <Tassadar> I thought I saw something like that in ueventd.*.rc files in boot image, but it must have been something else
Nov 20 19:50:33 <ogra-cb> hmpf
Nov 20 19:50:50 <ogra-cb> http://cdimage.ubuntu.com/daily-preinstalled/20121120.3/
Nov 20 19:51:06 <ogra-cb> but the bootimg file is missing :/
Nov 20 19:53:45 <ogra-cb> thats something i'll sort oout tomorrow morning though
Nov 20 23:25:32 <vanhoof> ogra-cb_: trimmed that down significantly, now checking out what I can do w/ abootimg :)
Nov 20 23:27:34 <vanhoof> $(grep mmcblk0p /proc/partitions | sort -gr -k3 | awk 'NR == 1 {print $4}')
Nov 20 23:27:41 <vanhoof> now if I only had a device to test ;)
Nov 20 23:40:01 <ogra-cb_> abootimg -i /dev/mmcblk0p2 |grep cmdline
Nov 20 23:40:20 <ogra-cb_> that'll give you the current commandline
Nov 20 23:40:57 <ogra-cb_> abootimg -u /dev/mmcblk0p2 -c "cmdline=my shiny new commandline"
Nov 20 23:41:06 <ogra-cb_> that will set the new one
Nov 20 23:41:56 <ogra-cb_> dont use /proc/cmdline here, it has a ton of hardcoded bootloader things in it that you dont want in the bootimg
Nov 20 23:44:46 <ogra-cb_> anyway, eod ...
Nov 20 23:45:28 <ptl> anyone has the same experience?
Nov 20 23:45:30 <ptl> hi, I have just tried a few sound programs in ubuntu on nexus7 and none worked
Nov 20 23:47:05 <ptl> even gst123
Nov 21 00:02:51 <lilstevie> ptl, is sound working in general?
Nov 21 00:14:20 <ptl> lilstevie: no. The only sound I ever heard in nexus7 ubuntu was the sound or the changing volume
Nov 21 00:14:34 <ptl> and even then the volume always starts muted and I have to raise it up
Nov 21 00:14:41 <ptl> then, it doesn't work
Nov 21 00:14:58 <ptl> tried with the bare minimun... gst123, a console program that uses regular gstreamer
Nov 21 00:15:05 <ptl> first time: reboot
Nov 21 00:15:17 <ptl> second time: says it's playing. Does not produce any sound!
Nov 21 00:15:56 <lilstevie> ptl, you did read the thing that says sound only works after suspend/resume yes?
Nov 21 00:31:12 <vanhoof> ogra-cb_: ah you're awake, just sent you some bits to check out
Nov 21 00:31:55 <vanhoof> ogra-cb_: thats much easier btw versus what I sent over abootimg wise
Nov 21 01:17:42 <ptl> lilstevie: good call. I think I read that, but I forgot.
