Blank screen after login on 2nd reboot after install or upgrade. 24.04

[Doug Smythies]

I installed 24.04 on a VM under my main Debian server host on 2024.03.17 and using the daily.
It worked fine.
After upgrade yesterday and after the 2nd re-boot the screen is blank after login. The screen is okay during re-boot, which I initiaited via an ssh session (I had installed openssh-server).

So, I re-installed using the 2024.03.22 daily. Same result.

I use VNC for my graphics on my VM's. I used this command to install:

virt-install -n desk-nn -r 8192 \
--disk path=/home/doug/vm/desk-nn.img,bus=virtio,size=50 \
-c noble-desktop-amd64-2024-03-22.iso \
--network bridge=br0,model=virtio,mac=52:54:00:0e:24:04 \
--graphics vnc,listen=0.0.0.0 --noautoconsole -v --vcpus=4

I do see issues with gnome-shell listed in /var/log/syslog, which I'll post later.

The VM seems to actually be running fine, based on my SSH session.

Note that interestingly, the newly installed VM screen did start working after an unknown amount of time.
I have reboot since and it still isn't working after some minutes. I had disabled screen locking and screen blanking when it last worked, which might be relevant as those wore the operating conditions of the previous VM.

After a fresh install (from the 2024.03.23 ISO in this case) everything is fine if I don't change the screen resolution from the default of 1014X768. Issues start once I change the display to 1680X1050, but seems to recover after an idle time screen blank/lock cycle. It seems I get into trouble because I normally operate with "Blank Screen Delay" set to never.

Workaround: Set "Blank Screen Delay" to 1 minute and screen lock off; After re-boot wait for the 1 minute with a messed up screen; Move the mouse or type a key, then the screen is fine.

As of recent updates, this issue seems to be fixed.
