Acer Chromebook CX5500

Note: Sound did not work consistently (would stop after a few minutes). Microphone did not work (No audio picked up). External mic did not work. External USB-C monitor did not work. USB-C dock did not work.

MrChromebox's firmware only provide the ability to flash SeaBIOS, not remove Google's firmware.

Suspend and poweroff cause the system to hang with up to the latest kernel on git on 2022-05-14.

To get suspend and resume to work, blacklist the atmel_mxt_ts and cros_ec_typec modules.

To do this in grub, edit /etc/default/grub

Add them to GRUB_CMDLINE_LINUX_DEFAULT.

   GRUB_CMDLINE_LINUX_DEFAULT=".. modprobe.blacklist=atmel_mxt_ts modprobe.blacklist=cros_ec_typec"

And then regenerate grub.cfg

   # grub-mkconfig -o /boot/grub/grub.cfg
