For AMD users, I finally managed to get my primary display to correctly update at 144Hz under Xorg by manually enabling TearFree rendering, as described here:
https://wiki.archlinux.org/index.php/AMDGPU#Tear_Free_Rendering I manually created the file: /etc/X11/xorg.conf.d/20-amdgpu.conf Inside it, I added: Section "Device" Identifier "AMD" Driver "amdgpu" Option "TearFree" "true" Option "VariableRefresh" "true" EndSection Then rebooted, and everything was -finally- nice and smooth! :D Note that I added the "VariableRefresh" option because my monitor supports FreeSync. Don't include that line if your monitor doesn't support variable refresh-rates. -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to mutter in Ubuntu. https://bugs.launchpad.net/bugs/1820832 Title: [nvidia] [xorg] multiple monitors: limits the framerate of faster 120/144hz monitors to 60hz To manage notifications about this bug go to: https://bugs.launchpad.net/mutter/+bug/1820832/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
