Bug description:
  My system:

  No LSB modules are available.
  Distributor ID:	Ubuntu
  Description:	Ubuntu Questing Quokka (development branch)
  Release:	25.10
  Codename:	questing

  Completely updated.

  After yesterday (2025-08-19) package updates, gdm3 stops on starting
  Ubuntu and It's impossible to start Gnome. Gdm3 freezes computer.

  On restarting computer, I see a lot of dmesg messages:

  nouveau cannot find any crtc or sizes

  I've blacklisted nouveau driver and installed several nvidia drivers
  and nothing works.

  My nvidia is:

  # nvidia-driver-assistant
  Detected GPUs:
    NVIDIA GeForce RTX 4070 Laptop GPU - (pci_id 0x2860)

  Detected system:
    Ubuntu 25.10

  Only works to install lightdm.
