** Description changed:
- I have a jammy laptop I installed today, and I used the same iso to
- create a jammy VM using virt-manager. In that VM, after the installation
- is complete, I cannot login. The screen either stays black, or throws me
- back to the login prompt. If I switch to Xorg login type, then it works.
+ Impact
+ ------
+ If you use virt-manager or gnome-boxes from a 22.04 host to install a 22.04
VM, the VM tries to use Wayland by default and only shows a black screen.
- More data coming up.
+ Test Case
+ ---------
+ 1. Install the osinfo-db update and gnome-boxes
+ 2. Close GNOME Boxes if it's running. Open GNOME Boxes.
+ 3. Click the + icon, then Create virtual machine from file. Select your
Ubuntu 22.04 desktop ISO.
+ 4. Follow the prompts to create your box.
+ 5. After it finishes installing, click the box. Log in. The screen should
show like normal.
- Suggested fix
- -------------
- I think we're going to want to revert
- https://gitlab.com/libosinfo/osinfo-db/-/commit/6ef9c9d4979d8
+ What Could Go Wrong
+ -------------------
+ This disables the 3D Acceleration (virgl) feature. The 3D Acceleration
feature is disabled by default (you have to manually enable it even after
installing a distro where it is offered).
- Try removing that section from your
- /usr/share/osinfo/os/ubuntu/ubuntu-18.04.xml before creating a jammy VM.
+ And you have to toggle the switch to keep it working:
+ https://gitlab.gnome.org/GNOME/gnome-boxes/-/issues/759#note_1386057
+
+ It's not clear why this black screen bug occurs, but there is an easy
+ fix to revert a not very useful feature that only landed in 22.04 about
+ a week ago.
