Graphics freezing during install

[Jane Atkinson]

QEMU/KVM vm

The install disk graphics froze up while removing apt-clone (near the end). I could move the mouse, but not click on anything. However the installation continued to run behind the scenes, and after waiting until there was no further activity in the virtual machine manager, I was able to boot successfully into the new system.

I was unable to retrieve any logs from the live ISO.

Changed the VM video from QXL to VirtIO, and freezing seems to have disappeared. Will need further testing to be sure.

No further freezing noted during ISO testing up to release date. I'll mark this invalid, as it was a VM driver issue rather than a problem with X11 or Wayland.
