If you don't like to wait for the patch to be applied, here is what you can do (for focal):
1. mkdir xorg-server && cd xorg-server 2. git clone -b applied/ubuntu/focal-security https://git.launchpad.net/ubuntu/+source/xorg-server 3. cd xorg-server/debian/patches 4. wget https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/1959995/+attachment/5572420/+files/nvidia-495-fix.patch 5. echo "nvidia-495-fix.patch" >> series 6. cd ../.. 7. dpkg-buildpackage -us -uc 8. cd .. 9. sudo dpkg -i ./*.deb 10. sudo systemctl reboot Done. Next you can install newer Nvidia drivers and there shouldn't be any issues.
