Well I just installed the Liquorix Kernel through apt like on the webpage and after rebooting (and selecting the default Pop_os kernel in systemd-boot) the kernel was loaded and the touchpad isn't working for some reasons.

OS: Pop_os 20.04

I found the device in multiple commands.

Also I don't know how to disable the kernel because in Systemd-boot I only see Pop_os current kernel and oldkernel

Hi Gladox114,

I just released an update that should fix your issue (in the next 2 hours pending build times). Last release I merged some HID/DesignWare patches that reduce power consumption under use, but it looks like some touch pads/screens malfunction with these enhancements.

Jan reverted the patches in upstream Zen Kernel but I hadn't released an update yet. Fortunately there's some other worthwhile updates this time around so I just spun out a new release.

5.7.0-8.2 should resolve your touchpad issues. Let me know if it doesn't.
