**** BEGIN LOGGING AT Fri Feb 08 02:59:59 2013 Feb 08 04:31:29 i'd like to be able to plug my laptop in to my arm box with usb, and have the arm box show up as a hdd, like tablets and phones do. what do i need to read about? Feb 08 06:00:00 where is the kernel .config file on ubuntu-server 12.04? Feb 08 07:27:48 good morning Feb 08 08:10:17 tripelb, https://wiki.ubuntu.com/Nexus7/Installation#Having_both_Android_and_Ubuntu_installed_for_dual_boot Feb 08 13:48:20 bug #1109197 Feb 08 13:48:21 Launchpad bug 1109197 in ac100-tarball-installer (Ubuntu) "fails to preserve mtimes" [Undecided,Fix released] https://launchpad.net/bugs/1109197 Feb 08 15:15:02 * xnox ponders about fastboot in main Feb 08 16:13:39 robclark: hi, back then you pointed me to some patches to make the pvr-omap module work with upstream kernel Feb 08 16:14:13 robclark: do you know if 1) 3.8/3.9 + your patches will work? Feb 08 16:14:31 robclark: 2) can you remind me where those patches are (can't find it right now) Feb 08 16:20:21 how far ubuntu arm is from running on samsung and nexus tablets? Feb 08 16:21:19 we have an image for the nexus7 Feb 08 16:21:31 no samsung not nx10 Feb 08 16:21:45 :/ Feb 08 16:22:17 Samsung note 10.1 here... would love to run ubuntu on this beast Feb 08 16:22:46 well, we kind of rely on having an unlockable fastboot on the device Feb 08 16:23:06 which binds us to nexus and probably asus atm Feb 08 16:23:29 yeah Feb 08 16:23:53 additionally you need working GLES Xorg drivers .... Feb 08 16:24:08 mali doesnt have any that are licensed in a way we could distribute ... Feb 08 16:24:08 How well the nexus 7 works? Feb 08 16:24:21 well, unity isnt a tablet UI at all ... Feb 08 16:24:31 beyond that fact it works quite well i'd say Feb 08 16:25:03 there's a meeting going on about that right now isn't there? Feb 08 16:26:05 yes Feb 08 16:26:10 in #ubuntu-meeting Feb 08 16:26:19 every friday at this time Feb 08 16:26:49 and I pretty much forget every friday :( Feb 08 16:26:50 well ill hope that linux would hit arm cpus, really like these silent machines Feb 08 16:27:09 ubuntu runs on arm machines since several years :) Feb 08 16:27:30 just not on many enduser devices yet, we're just starting with the nexus7 Feb 08 16:27:36 yeah but like all of them, tablets etc :) Feb 08 16:27:51 heh Feb 08 16:27:59 without unlocked bootloaders and GPU drivers, that will be hard Feb 08 16:28:15 right, it ios limited to usable HW Feb 08 16:28:42 there's another tablet that I've heard about, the Archos 101XS Gen 10 Feb 08 16:28:55 i had huge troubles with acer s3-931 laptop, uefi and ubuntu.. hate that new uefi boot Feb 08 16:29:13 has an OMAP 4470 SoC ... and has linux GPU drivers Feb 08 16:29:41 ppisati, I think ndec would know if there is some activity for pvr, etc, on 3.8.. Feb 08 16:30:08 shadeslayer, 4470 has android support.. not so much linux support tho, unfortunately.. a pity b/c x11 would do well with the 2d core Feb 08 16:30:09 ndec: ^ Feb 08 16:30:17 ndec2: ^ Feb 08 16:30:25 hey, does the arm version of ubuntu have the same features than normal ubuntu? Feb 08 16:30:47 lupus_: mostly, there's loads of stuff that doesn't compile with GLES so it's disabled Feb 08 16:30:54 robclark: in the mean time, can you remind me where those patches are? Feb 08 16:31:30 well .. maybe 'loads' is the wrong word here Feb 08 16:32:31 android lacks real multitasking, so thats the main reason why i would love to have ubuntu on tablet Feb 08 16:32:48 ppisati, on dev.omapzoom.org, there should be a ubuntu kernel tree.. look for the 1488 (iirc) branch.. that should be close enough to get started Feb 08 16:32:54 * robclark just heading out the door Feb 08 16:33:07 xnox, well, the spike persists quite long Feb 08 16:33:17 but anacron is indeed a good guess Feb 08 16:33:27 * ogra_ didnt think about that before Feb 08 16:33:47 i was suspecting apport or whoosie ... but then i couldnt see any spiking when watching them Feb 08 16:33:50 ogra_: apt-xapian can take a while on arm ;-) Feb 08 16:33:53 *whoopsie Feb 08 16:34:06 xnox, do we run it on every boot ? Feb 08 16:34:15 i thought thats only run at install time Feb 08 16:34:25 well after the initial flash it is your first boot ever so I expect everything to run. Feb 08 16:34:50 ah true, it is at install time.... unless timestamps are off =/ Feb 08 16:35:01 right Feb 08 16:35:08 for me it happens on every boot Feb 08 16:35:29 the desktop is fine after a few minutes ... but initially it spikes to 600M Feb 08 16:40:09 robclark: ok, should be this one - https://github.com/robclark/kernel-omap4/commits/pvr Feb 08 16:40:13 iirc Feb 08 16:40:34 robclark: oh Feb 08 16:41:08 robclark: from what I was told ( and from what I see on gitorious ) the kernel works fine Feb 08 16:41:20 https://gitorious.org/archos/archos-gpl-gen10/blobs/master/Readme.txt && https://gitorious.org/archos/archos-gpl-gen9-kernel Feb 08 16:42:22 anyway, arm stuff is so fiddly :( Feb 08 17:06:56 shadeslayer: problem with kernels for arm devices is that most of them totally ignore mainline. Feb 08 17:21:55 shadeslayer, yeah, kernel should work fine for *android*.. getting it working w/ linux and gfx accel, etc, will probably not be straightforward Feb 08 23:12:37 any of you guys know why I can't write on my MTD recovery partition without byte differences? I tried dd, flash_image and even tried a statically-compiled ddrescue to write it!!! log here: http://pastebin.com/xhRDazn8 Feb 09 01:41:07 Does anybody know a workaround for the plymouth error on boot? Feb 09 01:41:38 plymouth error ? Feb 09 01:41:51 I've tried adding overrides and deleting the init files but it still crashes and I can't boot Feb 09 01:42:15 what HW is that on ? Feb 09 01:42:55 It's on the Ubuntu launchpad, but the device is the new samsung chromebook Feb 09 01:43:09 The bug is reported on the launchpad, I mean Feb 09 01:43:18 get the source for ac100 tarball installer ... look at the postinst Feb 09 01:43:37 it adds a bunch of diversions ... apply them Feb 09 01:44:18 once thats dont add FRAMEBUFFER=True to your intramfs.conf ... then rebuild your intramfs and it should work Feb 09 01:44:30 s/dont/done/ Feb 09 01:45:13 hmm, even though, on the chromebook you could probably get through without the diversions Feb 09 01:45:13 Well right now I'm effectively locked out Feb 09 01:45:19 It doesn't boot Feb 09 01:45:33 can you change the kernel cmdline ? Feb 09 01:46:26 if so, add break=bottom ... boot and then exit with ctrl-d from the initramfs shell Feb 09 01:46:37 it should boot normally that way Feb 09 01:47:31 I'd need to build a new kernel to do this right? Feb 09 01:47:47 no, you need access to the bootloader for this Feb 09 01:47:54 or to the bootloader config Feb 09 01:48:05 ogra_: is this the general runes for how to boot with plymouth missing? Feb 09 01:48:11 I could really use this info... Feb 09 01:48:19 The chromebook bootloader is signed and locked Feb 09 01:48:42 wookey, the general rules is: make console-setup run in your initrd and plymouth will work Feb 09 01:49:10 ogra_: my problem is building plymouth... Feb 09 01:49:36 it'd be nice to test the system without having to do that Feb 09 01:49:59 well, mountall kind of relies on libplymouth for user interaction Feb 09 01:50:16 OK, so the short version is 'it's hard' Feb 09 01:50:30 if you can make sure to suppress all filesystem checks and boot with rw on the cmdline it should work Feb 09 01:50:32 in which case building it should be OK if I can just remove the X build-dep Feb 09 01:50:36 but will complain Feb 09 01:51:18 For some reason I thought 13.04 fixed this issue Feb 09 01:51:24 Apparently not Feb 09 01:51:41 no, its still being researched Feb 09 01:51:51 its a race condition ... a tricky one Feb 09 01:54:33 * ogra_ notes its kind of late and goes to bed Feb 09 02:02:03 Bleh Feb 09 02:02:28 Hard to believe there's no decently documented workaround for this issue **** ENDING LOGGING AT Sat Feb 09 02:59:57 2013
