Your touchpad shows up as a PS/2 device, right?
Yes.
I am not an expert with GRUB at all. For some reason, this sounds very aggressive and with a high chance of side effects. Theres nothing of worth on the device though, so I guess I’ll give it a try.
The Ubuntu live USB made no difference. Same problem plus Ubuntu kept crashing stuff all the time, so I guess I will stay on Fedora and just live with it.
