[libvirt-users] VM display is blank when open (but Gnome Boxes thumbnails ok)

[Michel Rozpendowski]

Hi,

I also posted this question on the IRC #virt channel but have not received
any reaction at the moment of posting this message to the mailing list.

Since I last turned off my laptop (Dell XPS-15-9570 running Ubuntu 19.04)
on Friday 10 May (I had to do it by long power press by the way), I am no
longer able to get the display of my VMs: I am getting a black screen, even
though I can see it running in the thumbnail of Gnome Boxes.
You can see the described behaviour on the following video capture:

Troubleshooting Log from Gnome Boxes is available here:

It was working all properly on Friday before I turn off my laptop.

Any clue what could be wrong and how I could solve this issue (I digged the
Internet for 2 hours without success)?

Thanks in advance for your help!

Kind regards,

Michel
