I'm running Ubuntu as a VMware guest. After upgrading to Ubuntu 22 and rebooting, the resolution was off: it should be 1600x900, but this wasn't a choice.

I followed the instructions at Screen Resolution Issue on Ubuntu VM running in VMware Workstation on Win7 host and at How to set the monitor to its native resolution which is not listed in the resolutions list? , and added the 1600x900 mode, but get errors when I try to use it, as shown below:

~$ cvt 1600 900

I'm not sure what to do next.

(VMware tools is installed - e.g. copy and paste between guest and host works fine.)

  • you are using Wayland, not xorg, which is why xrandr doesn't work. In Wayland with Gnome/Mutter compositor, if an option for the resolution you want isn't found and this link doesn't work, you're pretty much stuck (unless you fake the monitor's EDID data or some other hacky trick) – Esther Sep 04 '23 at 21:00
  • @Esther It worked fine before I upgraded to Ubuntu 22. – SRobertJames Sep 04 '23 at 21:08
  • from which version? Wayland only became default as of 21.04. – Esther Sep 04 '23 at 21:11
  • @Esther Yes, it was from 20. But: If switch VMware out of full screen, then back into full screen, it works! Is there a way to avoid doing this manually? – SRobertJames Sep 04 '23 at 21:12
