Add this file, assuming that your Xorg configuration is in /usr/local/etc/X11/xorg.conf.d/: $ cat /usr/local/etc/X11/xorg.conf.d/20-modesetting.conf Section "Device" Identifier "Zen5-iGPU" Driver "modesetting" Option "AccelMethod" "glamor" Option "DRI" "3" EndSection Section "Module" Load "dri3" Load "glx" EndSection With the above config file the "Fence fallback timer expired on ring ..." messages are still printed but very rarely and they don't seemingly affect system responsiveness. The original problem caused the Xorg based graphics screen to become incred= ibly slow. --=20 You are receiving this mail because: You are the assignee for the bug.=
