Also, for anyone else playing with ALARM for the first time, I'm finding the fbdev video driver better performing than the armsoc one as it stands..

Question for anyone - the touch pad is working really well in Arch - this is the main problem with ChrUbuntu at the moment, the touchpad is horrid..Does anyone have any idea if there's anything special been done for the touchpad in ALARM other than

Section "InputClass"
Identifier "touchpad"
MatchIsTouchpad "on"
Option "FingerHigh" "5"
Option "FingerLow" "5"
EndSection

in /etc/X11/xorg.conf.d/50-touchpad.conf (from: http://blogs.arm.com/software-enablemen ... hromebook/ )

I've been trying to cross-compile a newer version of Chromium than the one on the rootfs. But it's complicated and I haven't got it working yet. Perhaps I should try an x86 compile first. Anyway, I'd like to know how the existing binary was built if possible? The idea is to use the pepper flash plugin from the Arm ChromeOS which doesn't work with the current archlinux Arm Chromium binaries.

Not sure if this approach is useful, but here are some notes about my efforts to run a LAMP stack on my ARM ChromeBook.

This provides command-line access to arch only, but retains all of the existing ChromeOS gui features, drivers, etc. I use this for local WordPress development.

Hey this is brilliant - don't need the LAMP stack specifically, but this could be useful for much more! I hope you don't mind that I've just posted it to the Google+ ARM Linux community..

Wonder if we can get X up like in https://github.com/guillaumebrunerie/Chromiarch-OS

Obviously not the best audience here, but for newcomers, I've written a "get ALARM up and running with a working XFCE config on the ARM Chromebook" guide: http://craigerrington.com/blog/?p=32

Installed and working nicely
But no sound!!!!!

aplay -l shows the DAISY-I2S which i assume is ok.

I have tried coping /usr/share/alsa/ucm from chromeOS onto the rootfs, and calling

alsaucm -c DAISY-I2S


as suggested here http://blogs.arm.com/software-enablement/848-running-linux-on-the-series-3-chromebook/&sa=U&ei=xt72UKLfA7SN0wWtloGABg&ved=0CBwQFjAC&usg=AFQjCNHzkT-Z1DO8YIqm_JHl8PTvLLn-sg

No joy :( , no errors, but i hear no sound.

I have also tried unmuted all the channels in alsamixer and given them a little bit of volume (well all channels except MIC1 and MIC2 left and right mixers which made worrying noises come out of speakers.) - i have been a little cautious here though as i read other folk have blown their speakers by messing around in here.

I also tried copying the asound configs from /etc/, but this seems to want to set the sound to go through CRAS instead of alsa, which i dont think i want to do (do i?)

Can anyone shed some light as to what direction i should be looking at? im not much of an alsa guru.

For testing i am just doing 'aplay' on the wav files in /usr/share/alsa/

btw, everything else is working very nicely which for me includes

  • Xorg
  • ratpoison (normal use, but also added ratpoison mapping to fix brightness up & down keys)
  • uzbl-browser
  • vim, ssh, git etc.
  • mutt
  • ibus pinyin chinese input (type chinese in xterm!)
  • remapping the 'Input' key so i can paste in x-term (xmodmap does not work with ibus)
  • wireless using netcfg@.service (I had to tweak at as it was trying to load too early before /dev/mlan0 existed)


Any help with the sound would be greatly appreciated. Has anyone else had problems with this?

*UPDATE*
NEVERMIND!!! ignore me - i was being an idiot. the fact i had lots of chanels umuted was the problem, when i went back and muted everything i didn't need the sound just started working :)

This isn't really arch...but you guys will like it.

A google employee has released a script called crouton (you can find it here: https://github.com/dnschneid/crouton )

It installs a chroot with Ubuntu userland AND sets up an X server. You can run your chrome os desktop simultaneously to an XFCE desktop (or lxde, or kde, read his read me on github for details on the available 'targets')

You can swap 'xfce' in my instructions (below) for anything that appears I'm the targets folder on GitHub (above).

I've got detailed instructions on how to set it up - either to SD or internal - along with steps needed to prepare an SD: http://craigerrington.com/blog/crouton- ... m-sd-card/

It seems someone has OpenGL with hardware acceleration support using binary files from ChromeOS. Is it possible to port it to use in ALARM?

I know that binaries are evil but at least it can be a short-term solution
