ogra_*process11:30
mjrosenbodd, my chromebook does not seem to ant to update to 12.1011:30
mjrosenbit seems to really like 12.0411:30
ogra_mjrosenb, you need to tell update-manager that you want to run non LTS releases11:31
mjrosenbdid that already11:31
ogra_(somewhere in /etc/default)11:31
mjrosenboh, I think I did it through the gui.11:31
ogra_well, should be the same11:31
* mjrosenb verifies that he did this...11:32
hrwmjrosenb: I wish you lack with alsa mixer then11:32
hrws/lack/luck11:33
ogra_it is actually in /etc/update-manager/release-upgrades11:33
hrwmjrosenb: when you will start playing with alsa mixer switches be aware of smoke possibilities11:33
mjrosenbhrw: alsamixer isn't currently working, so upgrading can't hurt.11:33
xnoxogra_: I'll purge my downloads and redownload just in case.11:34
mjrosenbhrw: "smoke possibilities"?11:34
ogra_xnox, on the 16G model it should still work, it just wont use all of the available diskspace11:34
hrwmjrosenb: many people (including me) already fried speakers in chromebook11:34
ogra_mjrosenb, you can blow up the speakers apparently11:34
mjrosenbneato.11:35
hrwmjrosenb: smoke, melted plastic etc11:35
hrwand lot of heat of course11:35
mjrosenbI usually leave my laptop's speakers muted, so unless that option is inverted...11:35
hrwit is a bit more complicated11:35

ogra_gah11:41
ogra_the WLAN paswword input field doesnt take any input11:41
ogra_xnox, hmm, i thinnk compiz screws up onboard here11:43
ogra_i can provide the wlan PW via the NW applet ... but not through the installer11:44
xnoxogra_: interesting.11:44
ogra_and now i cant type in my name11:44
ogra_fridays image worked though11:45
ogra_sigh11:46
ogra_not being able to create a user is kind of a blocker11:46
* ogra_ reboots11:46
ogra_ah, better, a reboot fixed it (though probably because i didnt need to configure the wlan this time)11:49
hrwogra_: which keymap does ac100 uses?11:56
hrwogra_: kernel one, own xkb one, generic xkb one?11:56
ogra_consoilesetup as every ub untu out there11:57
ogra_*console-setup11:57
ogra_nexus7 install finished ... no issues beyond the kbd input stuff above11:57
hrwogra_: console-setup is just a package.11:59
ogra_yes, the package conatining all kbd and console font related setup bits12:00
ogra_it uses keyboard-configuration, xkb-data and kbd in the backend12:01
hrwok, but did you added ac100 specific keymap or not had to?12:03
ogra_why would i `12:04
hrwok12:04
hrwI am wondering how to handle chromebook keyboard. default keymap under chromium has set of useful mappings (pgup/down home/end) which are missing under ubuntu12:05

ogra-cb?16:26

ppisatior actually16:27
ppisaticpufreq was broken back then16:27
ppisatiin fact the default scheduler is performance16:27

ogra-cband thats an essential ubuntu default16:28

ogra-cbppisati, yes, we forcefully set it in userspace since 200816:28
ubot2Launchpad bug 971091 in Linaro-Ubuntu "Pandaboard ES freezes with the default CPU scaling governor ondemand" [Medium,Fix committed]16:28
ogra-cbi know, i see the bug (you mention it in the merge request too)16:29
ppisaticomment #16 says "AFAIK this should be solved in tilt-3.4, the problem was coming from frequency update code which should now be in good shape."16:29
ogra-cbif you disable it in kernel, did you test how the userspace bits behave if the module is nonexisting ?16:29
ppisatiwait16:30
ppisatii'm not using on demand on my boards16:30
ppisatii mean, no one forces it16:30
ogra-cbafaik the only prob we ever had with ondemand vs perfocmance that was actiually traceable against cpufreq was when we switched to cpuidle for a short period in precise16:30

tassadar_ogra-cb: will 12.10 ubuntu for nexus7 receive any updates or will you update only raring now?16:33
ogra-cbtassadar_, *i* wont touch quantal (but i also havent touched it since UDS)16:34
ogra-cbtassadar_, quantal is a very evil hacked up demo image that shoouldnt actually be used for more than demoing or looking at bugs16:34
ogra-cbraring recieves all the love16:35
tassadar_okay, thanks, one more annoying question: I would like ubuntu to be able to use some folder in /data/media/ as root folder and to be able to use .img file from flash drive as /. Is there a chance that modification like that would get into official ubuntu packages, if it is clean&properly done?16:37
ogra-cbyes, i think i told you about the work in grub that linaro is doing16:38
ogra-cbthats exactly using such a setup16:38
ogra-cbusing grub for a boot menu, then lupin for mounting an img16:38
ogra-cbatter all i would still suggest to just use the recovery partition, apply two minot changes to the userspace and be done though16:40
ogra-cb*minor16:40
tassadar_I don't want to lose recovery :/16:40
ogra-cb(ita auper trivial)16:40
ogra-cb*its super ...16:41
* ogra-cb cant see his keys in the dark16:41
ogra-cbyou can even do dual boot with the current images with a minor modificatio16:42
ogra-cbn16:42
tassadar_...continue...)16:42
ogra-cb?16:42
tassadar_what exactly do you mean by minor modification16:42
ogra-cbwell, flash bootimg to recovery and develop a patch for flash-kernel to respect that16:43
ogra-cbthats all dual boot needs16:43
ogra-cbppisati, is there no way to fix it in kernel ?16:44
tassadar_well, now that kexec-hardboot support is in n7 kernel, I can just use files from /boot folder in Ubuntu's root, which is awesome16:44
ogra-cbinstead of chopping out the option16:44
ppisatiogra-cb: the fix is "somewhere" is tilt-3.416:44
=== yofel_ is now known as yofel
ppisatiogra-cb: so it could be anywhere16:45
ogra-cbtassadar_, that wont save you, it will berak on the fist run of update-initramfs16:45
tassadar_yes, I'll have to remove the flash-kernel hook16:45
ogra-cbwhich you really want to keep in case someone uses i.e. an encrypted homedir16:46
=== Sv2 is now known as sv
ogra-cbtassadar_, if you want to avoid flashing, tra to have a file that exports FLASH_KERNEL_SKIP on boot16:47
ogra-cb(set it to something indeed)16:47
ogra-cbthat should save you16:47
ogra-cbthats better than removing packaged files16:47
tassadar_yeah, saw that in the hooks, that will indeed be better16:47
ogra-cb(they have a tendency to re-appear) ;)16:47
ppisatiogra-cb: anyhow, if you try to use a governor that is not available, it's a noop16:50
ogra-cbk16:50
ogra-cbstill, its an ubuntu default we dont offer16:51
ogra-cbalso are we sure the thing wont overheat if it permanently runs at full speed ?16:51
ppisatieither we do this, or we have to disable cpufreq16:51
ogra-cbwhich means full power anyway and bigger changes16:52
ogra-cbwell, seems there is no way around unless we offer a backported kernel then :/16:53
ppisatiogra-cb: btw, i was pretty sure i asked what our builders were running, and i was told it was performance16:54
ogra-cbppisati, ah, could be, i think they use ubuntu-core or something similar, that might not ship these userspace bits16:55
ppisatiogra-cb: so if they don't melt, i'm good with performance16:55
ogra-cbheh, k16:56
ogra-cbinfinity, so whats your plan wrt nexus7 and flavours16:56
infinityNot sure I have one.16:57
ogra-cbcurrently an ubuntu desktop build takes 130-150min16:57
ogra-cbif we switch doing tarball post processing on nusakan i guess we could get to 90min or so16:57
ogra-cbi have definitive requests from kubuntu. lubuntu and edubuntu16:58

ogra-cbthats not a question is it ?18:07
whatissixbyninesure looks like it to me o.O18:08
ogra-cbwhat exactlyy do you want to know ?18:08
whatissixbynineits enough information to correctly ident it (was 4412 rather than 4212 cpu btw)18:08
ogra-cbwe dont offer any images for phones18:08
whatissixbyninewell, i don't see an ubuntu for general exynos, but i do see one for odroid-x18:09
ogra-cbso its up to you18:09
ogra-cbthe userspace can surely run on that HW18:09
whatissixbyninethere was a great project with the motorola, vids and such, calls and texts working18:09
ogra-cbnot from here though18:09
whatissixbynineso your saying that no one bothered to pull the stuff in?18:10
ogra-cbthere is a commercial project from canonical, if you mean ubuntu for android18:10
whatissixbyninehm18:10
ogra-cbof which there is nothing more available than these videos18:10
xnoxpublically that is.18:11
ogra-cbubuntu-arm offrers current;y images for panda and beagleboard as well as the nexus7 tablet and the ac100 netbook18:11

ogra-cb(oh, and i forgot highbank and armadaxp arches on server)18:12
whatissixbyninehm18:12
whatissixbynineyeah i figured i would have to build it, but i thought i could take something like the odroid and hack it towards this. anyway not sure how to start.18:12
whatissixbynineso18:12
whatissixbynineWould like to get this going for it.. any advice? where do i start?18:13
whatissixbynineI can get chroot working, and i don't like it. vnc sucks.18:13
ogra-cbwell, userspace is usuallz always the same in ubuntu-arm18:13
whatissixbyninejust its crashing is a dealbreaker18:13
* xnox is not sure what "odroid" is that you are talking about.18:14
whatissixbyninethe ubuntu for android is what I am looking for18:14
ogra-cbso you need to know how to modify the bootloader and shoudl provide your own kernel18:14
whatissixbyninehttp://www.hardkernel.com/renewal_2011/main.php18:14
ogra-cbubuntu for android only exists in videos18:14
whatissixbynineok, so the repos for the packages i want arn't open source or openly available?18:15
ogra-cbno idea if there are repos18:15
ogra-cbthere is surely code, but yeah, thats not public yet18:15
whatissixbyninei dont really care if i got to build from scratch, i'm looking for a guide or howto or something18:15
ogra-cbwell, there is nothing yet18:15
whatissixbyninewell, how does one go about porting arm to a new device?18:16
whatissixbynineone that's NOT new18:16
whatissixbynine99% of what i need driver wise should be in the odroid image18:16
ogra-cbwell, userspace is usually ported :)18:16
whatissixbynine?18:16
whatissixbynineno comprende18:16
ogra-cbas long as you have an ARMv7 device all of ubuntu will just run18:16
whatissixbynineyes it is18:17
ogra-cbwhat you need to get your specific device going is ehough insight into the bootloader and boot process and your own kernel build18:17
whatissixbyninegive me a sec18:18
ogra-cb(as i said above a few lines)18:18
whatissixbyninei'm having trouble with ur head18:18
ogra-cball of ubuntu is built and available for ARMv7 ... if you have a working setup you can just apt-get install whatever you want ... not different to any intel PC18:20
ogra-cbbut whats not in ubuntu is any support for your device18:20
ogra-cb(bootloader and kernel)18:20
ogra-cbeverything above bootloader and kernel level is already there and usable ...18:21
ogra-cbso to enable your device you need to get these two bits working18:21
whatissixbynineok18:26
whatissixbyninethat makes a bit more sense18:26
whatissixbyninewhen I chroot into it, and do the vnc type install, that does not create an acceptable kernel/bootloader?18:27
whatissixbyninethat's actually a vm?18:27
ogra-cbno, that uses the android kernel and bootloader18:27
ogra-cbits a chroot, a VM emulates a machine18:28
whatissixbynineright, thought so18:28
ogra-cbthe chroot just uses the android and runs an ubuntu rootfs inside18:28
ogra-cbwhcih also means that various bits indeed wont work18:28
whatissixbyninegot it18:28
whatissixbyninehm18:37
Etherninyeah it would be great if you could just install full arm ubuntu with it's own kernel on android phones...19:07
Etherninlike the Nexus 719:07
whatissixbynineyes19:08
whatissixbynineEthernin, it really should be possible. very annoying that it's even this hard. even more annoying that there's little to no open projects for porting to new devices19:14
RaYmAnIt's not hard at all. Getting basic linux/debian/ubuntu running on any arm device where you can flash your own kernel is trivial..Getting it running good is a whole other matter of course.19:16
whatissixbynineRaYmAn, ok now your talking sir!19:20
whatissixbyninei have ability to dual boot into secondary rom, so initially i would slam in there19:21
whatissixbyninerunning good may indeed take a lot more, but i would be happy to get a start on19:21
whatissixbyninecurrently downloading the android sammy source for my i9300 and gonna try to slam the linux image from odroid inside it19:21
RaYmAnusually the easiest is just a couple of steps. 1) get a standard rootfs that doesn't start anything graphical - disable plymouth.Put it on an sdcard 2) build a kernel with fbconsole enabled and point cmdline at sdcard. fbcon should give some info19:22
whatissixbyninenot sure at all what i'm doing at this point, but i suppose i could update yall as we go19:23
