Xorg Black Screen when upgrading packages (after CUDA installation)

Thanks for the bug report. Next time the screen goes black and after rebooting, please run:

  journalctl -b-1 > prevboot.txt

and attach the resulting text file here.

If the black screen still occurs then please follow the instructions in comment #3. You do not need to reinstall.

If any log messages are related to the black screen then it might be these:

Tem 13 22:00:47 ms-7d86 kernel: [drm:nv_drm_master_set [nvidia_drm]] *ERROR* [nvidia-drm] [GPU ID 0x00000100] Failed to grab modeset ownership

But those messages are common enough in other peoples' logs that I'm skeptical they're related. More likely I think you just have a broken package combination.

Status changed to 'Confirmed' because the bug affects multiple users.

Confirmed. The last two (or three) routine system upgrades that had new nvidia packages have black screened during the upgrade.

This is a desktop. I can still log in via ssh from a laptop. Running 'top' shows:

Doing 'shutdown -r now' logs out ssh but doesn't reboot the machine. After waiting, pressing the hardware reset button on the case has no effect. It doesn't restart until a power down and cold boot.

I created a prevboot.txt from the instructions in an earlier comment; it is attached. It looks interesting, but I'll leave the analysis to the experts.

Yes, when installing Nvidia (prior to 525 just in case) turn off the monitor. you would need to time the time it takes to install the driver, update the kernel nvidia modules and more then force a reboot.

This only started happening after Nvidia 525 (Around February 2023), every new version after that creates this problem.

This also happened to me with a 2070 and Nvidia driver 535.xy to 535.104.05 .
That was a Wayland session, dual monitors...
I can probably dig up some logs.

This is what
  * debian/rules:
    - Do not start the systemd services on installation or upgrade, as this can
      lead to a black screen.
is supposed to fix right?

I updated to nvidia-graphics-drivers-535 (535.104.05-0ubuntu4) on Mantic (yes I know it's in -proposed, I wanted to test the fix) and it still happened during the update.

I can confirm exactly the same problem and behavior as Tod Hagan (tod222) wrote on 2023-08-06 #11.

I too have exactly the same problem as Tod Hagan (#11) described above

The same happened on my PC yesterday with upgrade to nvidia-firmware-535-535.113.01
