** Description changed: The main symptom is that, after the system boots up fine, reaches GDM, and the user logs in, the screen turns black before the Gnome Desktop appears. Switching to a text-based TTY and back to the Desktop works around it, making the Desktop show and work normally. This issue began when I was reinstalling from Ubuntu 22.04 (Which had no issues) to Ubuntu 24.04 LTS from a (non release upgraded) 24.04 installation (based on an amd64 Desktop installer ISO from last year). I ran a number of diagnostics which all yielded the same output as in this *report*. I ultimately ran sudo nvidia-xconfig with an output of "WARNING: Unable to locate/open X configuration file.New X configuration - file written to '/etc/X11/xorg.conf'" - This was to solve the phantom - "GPU-1" initialization failure seen in the logs ([EE] NVIDIA(GPU-1): - Failed to initialize). After 'Sudo Reboot'it seemed to have 'resolved' - the issue. A few successful logins later and instead of a black screen. - It was a snapshot of the grey login and the entire system was completely - froze. I rebooted a few times with the same outcome. + file written to '/etc/X11/xorg.conf'" - I cannot remember the step I + used after that, but it seemed to have 'resolved' the issue.

After much help and suggestions, I decided to do a BIOS upgrade and fresh installation to establish whether this situation also occurs on a clean 24.04.2 install and it does. These are the attempts I made on that new system to no avail: - - - Attempted, without change of symptoms: - Reinstall or Reset GDM/GNOME - - sudo apt update - sudo apt install --reinstall gdm3 ubuntu-gnome-desktop - - Attempted, without change of symptoms: echo "blacklist i2c_nvidia_gpu" | sudo tee /etc/modprobe.d/blacklist_i2c-nvidia-gpu.conf >/dev/null && sudo update-initramfs -u && reboot - Attempted, without change of symptoms: Login, from GDM graphical login, to Gnome on Wayland rather than Gnome on Xorg - Attempted, without change of symptoms: Setting, in gdm3.conf, WaylandEnable to "true" or "false", reboot One thing to note: The symptoms did 'NOT' occur when enabling automatic login, so that GDM would not ask for username + password. This may or may not be directly related to the repeatedly logged "Failed to grab modeset ownership" message, which has appeared in my diagnostics checks. I currently don't have a solution or have resolved my issue and instead - rely on TTF switching to get into the desktop. + rely on TTF switching to get into the desktop.
