[Heinrich Schuchardt (xypron)]

Setting the video resolution in Gnome is described here:
https://help.gnome.org/users/gnome-help/stable/look-resolution.html.en

The resolutions supported by your monitor can be displayed with the shell command edid-decode, e.g.

    edid-decode /sys/class/drm/card0-eDP-1/edid

The actual sub-path of /sys/class/drm/ depends on the connection to the monitor that you chose.

You should see the same resolutions as those stated in the Xrandr.txt that you supplied.

The default for Ubuntu with Gnome is to use Wayland and non Xorg. What is the output of
echo $XDG_SESSION_TYPE?

Are you able to change the resolution with the xrandr command in the shell?

Best regards

Heinrich

Thanks for the bug report.

The reason you have no resolution options is because the system has booted in recovery/safe mode which disables the graphics driver. You can tell this by the "recovery nomodeset" kernel parameters. Sometimes Ubuntu gets stuck in recovery mode if it was used during install.

Please reboot and tap Esc to access the grub menu while you still see the BIOS screen. Then select a non-recovery boot option.
