[HowTo] Provide System Information

This tutorial is superseded by this one. Remember all Tutorials are wiki posts that can be edited by TL2 (Trust Level 2) members and above. Welcome to Manjaro! To allow all of us helpful people on this forum TO HELP YOU, we need some basic information about your system. This probably means you described the symptoms of your problem, but now we need some more information to know where the origin of your issue is exactly. Someone else probably linked you to…

Same issue on gnome, kde, budgie and cinnamon so it doesnt seem to be DE related. Neither does it seem to wayland or xorg, as Ive tried both.

So - not a DE/compositor or distribution specific issue.

@duncaan

I know it works just fine when I use any 4.x kernel, the problem is only with 5.x kernel but Id obviously like to use that.

Aha - a kernel issue.
Check the used kernel driver and its possible options, perhaps there is something there to get better results.

Btw. crossposting only splits efforts.
