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.
Oh, Live USB is a good idea.
I really wanted to give Fedora a try, but maybe the time has come to give Ubuntu a second chance, when theres no solution.
I don’t think so. If the movement starts outside the “dead zone”, the touchpad works fine even within the “dead zone”. Only if the movement starts in the dead zone, it’s actually dead and its exactly the size of the “edge scroll zone”, when the option is enabled.
I had a Dell Latitude at work a few years ago, I don’t know if it was this exact model number, but the same series. And iirc on there was a driver option to disable the “dead zone” under microsoft.
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.
