The Xorg log was sent via email and contains (WW) NVIDIA: The Composite and Xinerama extensions are both enabled, which (WW) NVIDIA: is an unsupported configuration. The driver will continue (WW) NVIDIA: to load, but may behave strangely. (WW) NVIDIA: Xinerama is enabled, so RandR has likely been disabled by the (WW) NVIDIA: X server.
gnome-control-center should handle the situation better but that's a bit of a special graphical display configuration, did you try to do without xinerama? -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-control-center in Ubuntu. https://bugs.launchpad.net/bugs/1972037 Title: Stack Overflow - gnome-control-center Status in gnome-control-center package in Ubuntu: New Bug description: Program: gnome-control-center Installed version: 1:3.36.5-0ubuntu4 (ubuntu default download) OS: ubuntu 20.04.4 LTS GNOME Version: 3.36.8 (ubuntu default download) Windowing System: X11 Graphics: GeForce 8400GS/PCIe/SSE2 Driver: Using NVIDIA binary driver version 340.108 Source: download version from ubuntu Steps to reproduce: Reset GNOME settings with: dconf reset -f /org/gnome/control-center/ Open GNOME Settings with: /usr/bin/gnome-control-center Click on "Displays" and receive: Xlib: extension "RANDR" missing on display ":0".
