Dell Chromebook 11
The Dell Chromebook 11 (and newer chromebooks in general) features a "legacy boot" mode that makes it easy to boot Linux and other operating systems. The legacy boot mode is provided by the SeaBIOS payload of coreboot. SeaBIOS behaves like a traditional BIOS that boots into the MBR of a disk, and from there into your standard bootloaders like Syslinux and GRUB.
The instructions for getting Arch Linux to work on this machine are similar to the Acer C720 Chromebook, with a few differences.
First enable legacy boot / SeaBIOS from the developer mode of Chrome OS. Then install and boot Linux as you would on a traditional x86 BIOS system.
Enabling Developer Mode
To enter developer mode:
- Press and hold the
Esc+F3 (Refresh)keys, then press the
Powerbutton. This enters recovery mode.
- Now, press
Ctrl+D(no prompt). It will ask you to confirm, then the system will revert its state and enable developer mode.
Ctrl+D(or wait 30 seconds for the beep and boot) at the white boot splash screen to enter Chrome OS.
After changing to developer mode, configure Chrome OS so that you can log in, or use the guest account.
The version of SeaBIOS that ships with the Dell Chromebook doesn't work properly, and therefore you must patch it in order to get it to work.
- Open a crosh window with
- Open a bash shell with the
- Become superuser with
- Download the patched seabios.cbfs from https://code.google.com/p/chromium/issues/detail?id=348403#c4, and save it to Downloads.
- Patch SeaBIOS with the following commands:
# cd ~/Downloads # flashrom -r image.rom # dd if=seabios.cbfs of=image.rom seek=2 bs=2M conv=notrunc # flashrom -w image.rom -i RW_LEGACY
- Enable legacy boot with:
# crossystem dev_boot_usb=1 dev_boot_legacy=1
- Reboot the machine
You can now start SeaBIOS by pressing
Ctrl-L at the white boot splash screen.
Installing Arch Linux
Continue by following the Installation on a Haswell Chromebook.
Xorg Video Driver
$ sudo pacman -S xf86-video-intel
Touchpad Kernel Modules
Enabling the touchpad currently requires building a set of patched Haswell Chromebook kernel modules. Fortunately, ChrUbuntu provides a script for automatically building and installing these modules: cros-haswell-modules.sh.
A modified version for Arch Linux is available here cros-haswell-modules-archlinux.sh (tested with Linux 3.14). An older version for Linux 3.13 is available here cros-haswell-modules-archlinux-3.13.sh.
$ wget http://pastie.org/pastes/9106662/download -O cros-haswell-modules-archlinux.sh $ chmod +x cros-haswell-modules-archlinux.sh $ ./cros-haswell-modules-archlinux.sh
- Edit Xorg touchpad configuration file
Add the Xorg touchpad configuration below for better usability (increases touchpad sensitivity).
Section "InputClass" Identifier "touchpad wolf cyapa" MatchIsTouchpad "on" MatchDevicePath "/dev/input/event*" MatchProduct "cyapa" Option "FingerLow" "5" Option "FingerHigh" "10" EndSection
If you want to remove the "Right Click" behavior from the touchpad from the bottom right area (you can still right click with two finger clicks), you should comment out the following section from
#Section "InputClass" # Identifier "Default clickpad buttons" # MatchDriver "synaptics" # Option "SoftButtonAreas" "50% 0 82% 0 0 0 0 0" # To disable the bottom edge area so the buttons only work as buttons, # not for movement, set the AreaBottomEdge # Option "AreaBottomEdge" "82%" #EndSection
- Use graphical tool
Synaptiks is a touchpad configuration and management tool for KDE. It provides a System Settings module to configure basic and advanced features of the touchpad. Although it is said to be currently unmaintained. and seems to crash under KDE 4.11, it works well with this Chromebook, KDE 4.12.2. Another untility, kcm_touchpad, does not work at all.
Reboot for the touchpad to become operational.
The following are instructions to fix the suspend functionality.
Create the following
cros-ehci-disable.conf file. This unbinds the ehci-pci driver at boot, which spams the system journal on wakeup.
w /sys/bus/pci/drivers/ehci-pci/unbind - - - - "0000:00:1d.0"
Then, create the following
wakeup file. This disables all resume triggers from S3 except the lid, and therefore prevents random wakeups due to hardware interrupts. Feel free to experiment to see which of the /proc/acpi/wakeup switches actually causes this behavior, and update this wiki page.
echo LID0 > /proc/acpi/wakeup echo TPAD > /proc/acpi/wakeup echo TSCR > /proc/acpi/wakeup echo EHCI > /proc/acpi/wakeup echo XHCI > /proc/acpi/wakeup
Create a systemd service file for it as well:
[Unit] Description=Prevent random wakeups [Service] Type=oneshot ExecStart=/usr/lib/systemd/scripts/wakeup [Install] WantedBy=multi-user.target
Enable and start the service:
# systemctl enable wakeup.service # systemctl start wakeup
Then, add the following kernel boot parameters.
GRUB_CMDLINE_LINUX_DEFAULT="quiet tpm_tis.force=1 tpm_tis.interrupts=0"
Finally, rebuild your grub config and reboot.
Post Installation Configuration
For information on general Chromebook post installation configuration (hotkeys, power key handling ...) see Chromebook#Post_Installation_Configuration.
The audio configuration is similar to the Acer C720.
- The 64-bit installer in Arch Linux installation ISOs newer than 2013.10.01 causes an immediate system reset
- Syslinux fails to set the bootable flag with
syslinux-install_update -i -a -m. After setting the bootable flag manually in
fdiskand installing Syslinux to the MBR with
syslinux-install_update -i -m, SeaBIOS boots syslinux, but syslinux then complains about a missing OS. Use GRUB for now.
- Suspend on Linux kernel version 3.14 is broken; the Chromebook reboots on suspend instead.
