Important Notes

Installing Debian onto the Chromebook Pixel is a slightly unusual affair due to its signed bootloader, but is quite straightforward providing the instructions are followed precisely. See #Installing Debian.

Each time you boot once Debian is installed you need to press Ctrl-L when presented with the white warning screen by coreboot. SeaBIOS will then be loaded, which will load Grub. This is unavoidable (without flashing a modified version of coreboot).

Closing the lid without suspending the laptop can cause the touchscreen to go crazy (at least with the 3.10 kernel). To resolve this reload the touchscreen module with this command after reopening the screen:  modprobe -r atmel_mxt_ts && modprobe atmel_mxt_ts 

It's very important not to let the battery run completely out or you may lose all your data! See #Ensuring the battery doesn't run right down.

Kernel

A 3.10 kernel or later is required for all of the drivers to work. However the touchscreen & touchpad don't work with the latest backported kernels (3.10 and 3.11) because the CHROMEOS_LAPTOP option is disabled in those versions. That should change soon; see #Useful Links. For now you need to compile your own kernel with the .config.

Installing Debian

Follow steps 1-9 of DaveM's excellent Installing Linux on the Chromebook Pixel guide. This will get Debian installed and working, except for the touchpad & touchscreen.

You can then either follow his remaining instructions to compile the necessary modules, or compile your own kernel using the .config file attached to this wiki.

Configuration

Display

The size of the screen isn't automatically detected, which leads to incorrect DPI assumptions. To fix that create a file called /etc/X11/xorg.conf.d/90-monitor.conf containing this: 

Section "Monitor"
    Identifier  "<default monitor>"
    DisplaySize 270 180 # millimeters
EndSection

Power Management

Suspend

For suspend to work reliably you need to add the following line to /etc/modules (source): 

tpm_tis force=1 interrupts=0

Ensuring the battery doesn't run right down

The Chromebook Pixel has a very unfortunate design bug where if the battery is completely empty it will not allow you to boot up an operating system other than ChromeOS, requiring a reinstall of Debian. This is because it the "Developer Mode" setting is battery backed, so is lost if the battery runs out, and it can't be set except in a running ChromeOS install. Needless to say this is very bad news! Source.

It is therefore advisable to make sure the battery never gets to empty by forcing a shutdown when the battery level is low. You can do that with various graphical power management tools, or by creating an automatic shutdown daemon.
