Has anyone succeeded in installing a plain vanilla Ubuntu (or other Linux distribution) install on the Acer C7 Chromebook? I am aware of the ChrUbuntu project but would prefer a plain vanilla Ubuntu install if possible. I am not sure how the special google firmware influences a standard Linux install?
Chrubuntu IS a plain vanilla Ubuntu installation as far as I can tell after a couple of weeks of daily usage. I'm using it with the MATE desktop; I am not a big fan of Unity, but it runs very, very well. I've installed some pretty demanding games (Bastion, Portal, Half-Life 2), and they play at full speed. I did install video upgrades for the Sandy Bridge Celeron from the ubuntu-x-swat PPA, and I have very few complaints about this $200 computer which did not come with a Windows tax.
fyi: there is a fix for the problem of the internal mic not recording after the Ubuntu install; read the bug fix here: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1093395
I know this reply came a bit late, but if you're still looking to replace ChromeOS completely with plain vanilla Ubuntu, have a look at this article: http://johnlewis.ie/pre-built-coreboot-firmware-for-chromebooks/
Warning, this involves hardware hacking and will most certainly void your warranty. I've detailed my personal experience here: https://askubuntu.com/a/361561/97517
