Upgraded from 18.04 LTS with no additional drivers to 20.04 LTS updated until 1-Oct-2020.

No HW changes since previous versions, back to (IIRC) 12.04 none of which showed this problem -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1078695 Title: xrandr : Failed to get size of gamma for output default To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/x11-utils/+bug/1078695/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
