Tested again a few times: I confirm that switching to nouveau removes the mouse trail but slows down the desktop to unworkable.
To clarify #6: It could be that in my first test I did not reboot, although this is quite unlikely. I could re-install the OS if you want me to try to replicate this. What is for sure is that the Driver's GUI [attached] has issues: 1) After switching to nouveau (and reboot) it does not highlight "nouveau", but points to a new menu entry, "Continue using manually installed driver". 2) Options of switching drivers are greyed out after switching to Nouveau. 3) Claims that my Wifi is not working, but it works just fine. Annother strange behaviour occurred today: The reboot after switching to Nouveau gets stuck at every boot with /dev/sda6 clean, 234123/26879978 files, 4048798/11234253 blocks Workaround is booting into recovery, then select boot from there - it boots. This problem does disappear after switching to the proprietary display driver. ** Attachment added: "DriverGUI.png" https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/1874856/+attachment/5363972/+files/DriverGUI.png -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xorg-server in Ubuntu. https://bugs.launchpad.net/bugs/1874856 Title: Unwanted mouse trail Status in mutter package in Ubuntu: Incomplete Status in xorg-server package in Ubuntu: Incomplete Bug description: Moving mouse leaves a trail of squares for a few seconds on a fresh 20.04 install.
