Black screen with only cursor

[Peturrr]

I run 24.10 for a while already, and today after doing a apt-get upgrade and rebooting I am now greeted by a weird startup melody and a black screen with only my cursor.

I can't seem to switch to console and also when disabling wayland in gdm3 config, I still get this black screen, rendering my desktop unusable.

I am using latest Nvidia drivers (running a GTX 4070 Ti Super). Not sure what happened here?

Same here, you need to downgrade gnome-shell to https://launchpad.net/ubuntu/+source.../46.4-1ubuntu1 and probably mutter from 15 to 14.

That's what I did at least. There's like 10+ packages you need to manually downgrade using dpkg or whatever.

Hello,

installing today's iso I was also greeted with this nice melody, yet things were crisp and nice. Installation took place under virtualbox.

Regards!

Could one of you affected by the issue file a bug for it?

Same here. RTX 4090, nvidia-driver-550. The problem is there is nothing unusual in the logs. Xorg, syslog, gdm. By switching to Xfce the login screen appears, screen goes black after login. Will try the above mentioned workaround.
Some more observations:
- have been running Oriole builds with no issues, upgrading every day, on the day when the build with login sound was introduced the graphics broke - could it identify the bad commit?
- driver itself looks running without issues, nvidia-smi command is showing Xorg and Gdm well loaded in VRAM when the screen is black and only mouse pointer is visible
- size of the pointer looks normal, so likely not a wrong resolution problem
- changes in Xorg.conf don't make any difference
- changing the default nomodeset=1 to 0 under modprobe.d nvidia config causes X crash
- changing Wayland to enabled in gdm config changes the behavior to no-signal to monitor

Well that was basically the day when gnome-shell was updated from 45 to 46. However, there are several related packages in that upgrade so it's a little complex to try downgrading.

Did you have any luck with that issue? I'm also looking into fixing it, but still nothing so far

Yes, will do. Can you point me to where I should do that? Launchpad Gnome-Shell?

[jbicha]

In this particular case, this is my recommendation:

File the bug at https://bugs.launchpad.net/ubuntu/+s...ug?no-redirect

Make a note of the Launchpad bug number that is assigned. Then, on your affected system:

Install the broken gnome-shell updates if they aren't already installed.

Run this command using the Launchpad bug number instead of BUGNUMBER.

apport-collect BUGNUMBER

Normally, you could just run ubuntu-bug gnome-shell to avoid needing to do the apport-collect step, but the problem here is that you aren't able to run your web browser on the affected system to finish filing the bug.

Hello, same here. I used shift-key on startup to get to Grub menu and select previous kernel image so I can use my computer. The automatically updated one, 6.8.0-40 didn't boot. It says I/O error dev sda, sector 88152992.
