Xubuntu display resolution fails on KVM/QEMU

Pre-Release Discussion

If this is QEMU/KVM/virt-manager-specific: in case it might be useful, in VMs I actively try to avoid setting resolution in the desktop environment’s settings, prefer to set resolution by other methods.

For QEMU/KVM/virt-manager specifically:

  • You can set a specific fixed resolution in the VM’s settings
  • If your VM’s Video device is either QXL or Virtio, installing and enabling spice-vdagent in the guest can dynamically resize the VM’s display to the size of the VM window.

Some related details in this post.

If you want to set the resolution from inside the guest, another option is “Method 1” from this link.

Not sure whether your goal is to change your VM’s screen resolution or if you’re only seeking to troubleshoot the Xfce display settings related freeze - if the latter, sorry for the noise.
