Fuzzy graphics after upgrading to Ubuntu 20.04
I solved my fuzzy graphics issue which is related to Intel Drivers. A bug is also reported on Intel driver artifacts. Following the answer provided here this command line solved the issue:
sudo apt purge xserver-xorg-video-intel
Reboot and everything is back being normal.
Same problem here with an Intel UHD Graphics 630 (Desktop) after upgrading from 19.10 to 20.04.
Completely solved by deleting a custom Intel Xorg configuration file I had created in the past ― on my setup it was /etc/X11/xorg.conf.d/20-intel.conf
, and contained:
Section "Device"
Identifier "Intel Graphics"
Driver "Intel"
Option "AccelMethod" "sna"
Option "TearFree" "true"
EndSection
