There’s been a bug with peripherals (on some mouses) on arm. Usbhid.mousepoll value can be changed.
Also I noticed a bug on xfce desktop on arm, there’s a line that runs across bottom of the screen I can’t seem to figure out how to get rid of. Overlaps all of the windows.
Setting up printers on arm (due to most drivers being for amd64) as IPP if compatible.
Gaming controllers : kernel updated in unstable with modules added xpad. Once its released to stable, there might not be any config required.
Would be nice to see how to correct some of these issues or ways to tweak device to get around them.
