From nnelson at infowest.com Sat Jun 20 02:17:44 2020 From: nnelson at infowest.com (Neil Nelson) Date: Fri, 19 Jun 2020 20:17:44 -0600 Subject: Only 1024x768 display resolution for Kubuntu in KVM VM Message-ID: <596f2c36-d0fa-6d3d-ed03-851252f85dc8@infowest.com> On Ubuntu-Studio yesterday I saw they were going from Xubuntu to Kubuntu for the 20.10 release and made some good statements about it. I downloaded the Kubuntu 20.04 ISO and created a KVM VM on my Xubuntu host to check it out. The low memory and CPU usage are very good and it has a great look. I tried to change the resolution to 1920x1080 but it would instantly snap back to 1024x768 each time. I have a 1920x1080 resolution in both Xubuntu and Ubuntu VMs and my monitor and video card support that resolution. It would be great to have the higher resolution for the Kubuntu VM.

If you are on KVM (Virt-Manager?), it would be VGA not QXL. This is for KDE only; other DEs I used did not exhibit this issue. Don't know the technical details for this issue.

That can run higher resolutions, the question now is how you have started your guest. Did you run qemu-system-* directly, if so which commandline arguments did you use? If you run it through libvirt what does the guest XML definition look like? Finally in the guest you might take a look with `lspci -v` which virtual graphic card you got presented. E.g. in case you fell back to the much older cirrus default and that with low memory it could explain the lack of resolution options.
