**** BEGIN LOGGING AT Sun Mar 10 02:59:58 2013 Mar 10 05:43:17 hello Mar 10 05:43:34 chromium 25 build failed because headers missing :( Mar 10 05:43:38 https://launchpad.net/ubuntu/+source/chromium-browser/25.0.1364.160-0ubuntu1/+build/4358080 Mar 10 05:44:09 v8/src/../include/v8stdint.h:34:19: fatal error: stdio.h: No such file or directory Mar 10 05:45:14 https://launchpad.net/ubuntu/+source/chromium-browser/25.0.1364.160-0ubuntu1/+build/4358080 Mar 10 08:04:20 hi i came here for asking if there is any plan for supporting ubuntu on samsung's arm chromebook? Mar 10 08:35:34 ynezz, not officially, but there is a lot chromeboot work from the community and it works flawless with ubuntu Mar 10 08:36:07 * ogra_ hugs xnox Mar 10 08:36:39 lilstevie, well, then you would need to crack the signature ... carcking would be involved somewhere in the process :) Mar 10 08:38:30 ogra_, why would you need to crack the signature, low integrity level code (metro apps) don't have the same code sign integrity, also you could just not worry about checking the sig in wine for arm :p I think the bigger task is trying to emulate the metro APIs Mar 10 08:39:10 heh, yeah, well, thats a requirement in general for wine :) Mar 10 08:39:43 yeah Mar 10 08:41:45 ogra_: i have installed the chrUbuntu Mar 10 08:42:03 but that's lack of multi-touch supoport Mar 10 08:42:24 and its X is reaaaaaly slow while the tty is quite flex Mar 10 08:42:37 yunfan, using unity ? Mar 10 08:43:02 (and sorry ynezz) Mar 10 08:43:14 ogra_: yep, i just wondering if they have some debug code like sleep 99999 Mar 10 08:43:29 haha Mar 10 08:43:31 no Mar 10 08:43:48 but there is definitely something wrong with the GLES support for mali ... Mar 10 08:43:57 everytime when i press the key, i need to wait for the terminal window's response action Mar 10 08:44:14 gles itself runs fine for me but unity seems ot still do SW rendering nontheless Mar 10 08:44:35 oh, its not that bad for me Mar 10 08:45:11 its actually usable ... just not as fast as it could be, did you copy the binary libs from chromeos ? Mar 10 08:45:20 i heard that ubuntu touch would be run on galaxy note2 which share the same cpu with my chromebook Mar 10 08:45:44 i didnt , just follow the install step from chrUbuntu Mar 10 08:45:45 ubuntu touch is based on cyanogenmod Mar 10 08:45:56 mabybe they did in that shell script Mar 10 08:46:01 oop Mar 10 08:46:20 unless someone has chromebook support added to that it wont "just run" with code from another device Mar 10 08:46:36 and ubuntu touch doesnt use X at all Mar 10 08:46:42 got it, that's why you have ac100 supporting? Mar 10 08:46:48 i also own an ac100 Mar 10 08:47:04 which after update to the armHF version, runs very fast Mar 10 08:47:21 i started the ac100 port several years ago ... there wasnt even a tought for ubuntu touch ... Mar 10 08:47:23 but the battery life is terrible Mar 10 08:47:46 and keeping ac100 alive was a constant matter of pain dealing with the binary drivers Mar 10 08:48:09 also ac100 is very much a netbook Mar 10 08:48:40 i still love my ac100 and the 8-9h battery life are definitely unbeaten Mar 10 08:48:49 IMO much better suited to a desktop environment though Mar 10 08:48:52 so the simple answer is there're not an official plan for supporting samsung's chromebook ? Mar 10 08:48:53 but 512M just hurt Mar 10 08:49:46 well by using LXDE, i feel the ac100 is just enough , but the battery which is a real problem , i cant accept 1.5 hour Mar 10 08:49:53 and its powerline is ugly Mar 10 08:49:58 yunfan, canonical wont support it ... but hrw did already so much packaging work that we could probably build images for it at some point if someone does the work to implement that in the build system Mar 10 08:50:16 yunfan, your battery is clearly broken Mar 10 08:50:35 i get 8-9h out of one charge Mar 10 08:50:41 ogra_: i have send to the factory and they told me its normal :[ Mar 10 08:50:47 ogra_: well another question Mar 10 08:50:53 and i own three ac100's which all get me that Mar 10 08:50:54 yunfan: you really want to abandon unity/3d in favour of something working Mar 10 08:51:21 hrw, no, you want to file bug reports and pester daniel van vugt :) Mar 10 08:51:36 ogra_: I dropped opengles driver from ppa Mar 10 08:51:50 ogra_: no redistribution license Mar 10 08:51:59 ogra_: can you recommend a quick turtorial for my learning arm asm ? i am a python engineer currently, i knew those binary trans 2's complement number things Mar 10 08:52:02 good move ... better have a howto for people to copy the stuff from chromeos Mar 10 08:52:15 ogra_: will do such Mar 10 08:53:09 yunfan, so your answer is, no, chromebook will never get official support, but it might come to a level where the ac100 is at some point Mar 10 08:53:28 (which never was officially supported) Mar 10 08:53:47 ogra_: that's good if it could arrive the ac100's level Mar 10 08:54:17 yunfan: so far there are nearly no people doing work which ac100 community did Mar 10 08:54:25 ogra_: what about my secondary question? Mar 10 08:54:46 building image is a matter of someone investing the time into implementing that in the build system ... for ac100 it was me who did that in his sparetime ... i dont currently have that much of spare time to do it again for a new device Mar 10 08:54:51 I packaged kernel, handled opengles, x11 driver and had fingers in few other places but my time is limited Mar 10 08:54:57 hrw: yep, but sonner or later , people would do that, its just that device is in really use Mar 10 08:55:24 during Linaro Connect Asia I was fully ARMed - did not took x86 at all Mar 10 08:55:39 * ogra_ does that since 3 years :) Mar 10 08:55:57 but i'm a masochist if it comes to HW :) Mar 10 08:56:05 :D Mar 10 08:56:18 guys, can you recommend a quickly arm asm turtorial for me plz? Mar 10 08:56:26 btw, i prefer att syntax Mar 10 08:56:31 the arm page might have some Mar 10 08:56:46 * ogra_ tries to stay away from asm if possible Mar 10 08:56:53 its not that quick by therir documents Mar 10 08:57:05 asm? Mar 10 08:57:14 why anyone wants to learn asm Mar 10 08:57:15 yep Mar 10 08:57:36 ~armarm Mar 10 08:57:37 because i want to port my forth impl on arm platform Mar 10 08:57:45 yunfan: do it in C Mar 10 08:58:01 use gcc atomics Mar 10 08:58:02 C version will be faster, trust me Mar 10 08:58:03 which require emmit machine code while doing metaprogramming Mar 10 08:58:29 hrw: true man wont use c for their own forth :] Mar 10 08:58:48 C ver can also be tunned for a8/a9/a7/a15/a53/a57/aWHATEVER Mar 10 08:59:02 even if there is a massive performance advantage over asm ? Mar 10 08:59:11 good luck with hand tuning for a7/a15 Mar 10 08:59:19 its just joking : ] i am intereting of low level things Mar 10 08:59:21 (and portability across the different arm arches) Mar 10 08:59:54 but i dont like x86, so what i can choose is mips or arm. consider that i have two arm devices , so i choose arm Mar 10 09:00:21 well, i'm not touching asm ... and honestly never had to apart from fixing horrid stuff of people that (falsely) thought they need asm in their code to be fast Mar 10 09:00:52 so i cant point you to a tutorial ... Mar 10 09:00:55 i am just reading CSAPP the greate book which lead me so interesting of low level things Mar 10 09:01:34 well, try #linaro during the week, you might find some asm specialists there Mar 10 09:01:56 no i am not need asm for just be fast, as a python engineer, i knew that most times implments that i wrote in c wont be faster that the python official's Mar 10 09:01:58 (but i'm pretty sur ethey'll tell you the same) Mar 10 09:02:02 the only time we use ASM is for payloads that need to be super small Mar 10 09:02:14 * lilstevie doesn't know asm Mar 10 09:02:16 :p Mar 10 09:02:40 i want to learn asm is that i am interesting of it and the low level things made me understand easier by the simple term and less complex Mar 10 09:02:48 * ogra_ knows some from his teenager days ... but thats looooong ago Mar 10 09:03:10 i will try that , thanks ogra_ Mar 10 09:03:40 that is a single case where asm is probably the better approach though, the whole bootloader situation on x86 is a good show of why doing something in asm is a bad idea Mar 10 09:03:53 syslinux or grub would be wonderful on arm Mar 10 09:04:13 ogra_: as a chinese , i might just acts like your teanager in CS knowledges ,i bought PC when i was in college Mar 10 09:12:15 lilstevie, there is some arm code in grub ... Mar 10 09:12:56 just nothing finished ... Mar 10 10:18:39 lilstevie: I saw grub on arm already Mar 10 10:18:44 Linaro is working on it Mar 10 11:09:26 hrw, heh yeah, but it is still nowhere near ready from what I've seen Mar 10 18:24:15 hi, I'm about to add http://paste.ubuntu.com/5602702/ to our version of flash-kernel Mar 10 18:24:29 it copies the right device tree from /lib/firmware to /boot Mar 10 18:24:33 so uboot can find it Mar 10 18:24:52 does this makes sense or is it totally bogus? Mar 10 18:32:17 ok, it's totally bogus to ask such questions on sunday eve Mar 10 19:04:31 (install to /etc/kernel/postinst.d, if someone wonders) Mar 10 23:09:41 marvin24, you mean to your kernel package, not flash-kernel, right ? Mar 11 02:46:25 Anyone install Ubuntu on the Lenovo Yoga? **** ENDING LOGGING AT Mon Mar 11 02:59:58 2013
