HP Chromebook 14
The HP Chromebook 14 (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 GPT of a disk, and from there into your standard bootloaders like Syslinux and GRUB.
Post Installation Configuration
Add the Xorg touchpad configuration below for better usability (higher sensitivity).
Section "InputClass" Identifier "touchpad peppy cyapa" Driver "synaptics" MatchIsTouchpad "on" MatchDevicePath "/dev/input/event*" MatchProduct "cyapa" Option "FingerLow" "10" Option "FingerHigh" "10" EndSection
Reboot for the touchpad to become operational.
Keyboard Keymapping Fix
We will create a custom hwdb config file to bypass the default mapping in
/usr/lib/udev/hwdb.d/60-keyboard.hwdb of the keys between escape and power so they will work as F1-F10 and the search button as Super_L/Mod4.
Add the following to the new hwdb config file, save and exit.
# Chromebook 14 fix evdev:atkbd:dmi:bvn*:bvr*:bd*:svnHewlett-Packard*:pnFalco:pvr* KEYBOARD_KEY_3b=f1 KEYBOARD_KEY_3c=f2 KEYBOARD_KEY_3d=f3 KEYBOARD_KEY_3e=f4 KEYBOARD_KEY_3f=f5 KEYBOARD_KEY_40=f6 KEYBOARD_KEY_41=f7 KEYBOARD_KEY_42=f8 KEYBOARD_KEY_43=f9 KEYBOARD_KEY_44=f10 KEYBOARD_KEY_db=leftmeta
hwdb.bin by running
# udevadm hwdb --update
Reboot to load the updated hwdb database.
After each upgrade of Systemd, its installation script will rebuild the database automatically so we do not need to take care of it.
See Map scancodes to keycodes for more details.
Adding hotkeys back
Once you have applied the above fix you can set the function and arrow keys to act similar to how they are in ChromeOS using a modifer key. The example below uses Mod4 (Search on the chromebook's keyboard). This can be changed to Control or Alt if you prefer.
First make sure you have all the needed packages:, , , AUR, .
.xbindkeysrc in your home folder:
#Delete "xvkbd -xsendevent -text '\[Delete]'" Mod4 + BackSpace #End "xvkbd -xsendevent -text '\[End]'" Mod4 + Right #Home "xvkbd -xsendevent -text '\[Home]'" Mod4 + Left #Page Down "xvkbd -xsendevent -text '\[Page_Down]'" Mod4 + Down #Page Up "xvkbd -xsendevent -text '\[Page_Up]'" Mod4 + Up #Volume Controls #Mute "amixer sset Master toggle" Mod4 + F8 #Volume Down "amixer sset Master 2%-" Mod4 + F9 #Volume Up "amixer sset Master 2%+" Mod4 + F10 #Backlight #Dim "xbacklight -dec 10" Mod4 + F6 #Brighten "xbacklight -inc 10" Mod4 + F7 #Back,Fwd,Reload as Multimedia Prev,Next,Play #Play/Pause "xdotool key XF86AudioPlay" Mod4 + F3 #Prev Track "xdotool key XF86AudioPrev" Mod4 + F1 #Next Track "xdotool key XF86AudioNext" Mod4 + F2
To activate it when you login add
to your .xinitrc, or whatever your DE uses for startup.
Locating the Write-Protect Screw
- Remove the visible screws and another 4 hidden screws under rubber stubs (not the rubber feet) at the bottom.
- Flip the laptop right side up and use a thin blunt object to pry the keyboard surface from the bottom half.
- The bios screw is located to the left of the fan, it can be recognized by the fact that the copper circle it sits on is split in half "( )" vs "O". The screw connects the two halves, making the bios unwriteable.
- Once this screw is removed, it is advisable to unplug the battery and plug it back in to ensure that the removal is recognized.
