Title:
[ASUS VivoBook X541UJ] Keyboard and touchpad don't work on kernel
5.8.0.29, but 5.4 or 5.8.16 work
Status in linux package in Ubuntu:
Confirmed
Bug description:
when I updated my system to ubuntu 20.10, the keyboard and mouse no longer
worked after a little investigation, I found out the kernel causes this
problem, downgrading to linux 5.4 or upgrading to linux kernel 5.8.11 solved
this issue, I also found that this problem is present on other ASUS laptop
models ( my laptop is ASUS) so you may want to investigate this issue to update
your default 20.10 Linux kernel.
