I was wrong about using wayland. Like you can see from `nvidia-smi` I am using Xorg it seems.

Status in gnome-shell package in Ubuntu: Incomplete Status in nvidia-graphics-drivers-515 package in Ubuntu: Incomplete Bug description: I have a Thinkpad P15 with a A2000 GPU with Ubuntu 22.04.1 LTS. This happens using Wayland and nvidia cuda drivers. It seems like the system uses very long to identify the screens. This happens when I use external monitors, but also when only using the laptop screen. Changing the screen layout takes so long that I am unable to accept the change before it is reverted to the previous. Only the mouse pointer is visible, the rest of the screens are black during this process. $ apt-cache policy cuda cuda: Installed: 11.7.1-1 Candidate: 11.8.0-1 Version table: 11.8.0-1 600 600 https://developer.download.nvidia.com/compute/cuda/repos/ubuntu2204/x86_64 Packages *** 11.7.1-1 600 600 https://developer.download.nvidia.com/compute/cuda/repos/ubuntu2204/x86_64 Packages 100 /var/lib/dpkg/status 11.7.0-1 600 600 https://developer.download.nvidia.com/compute/cuda/repos/ubuntu2204/x86_64 Packages $ nvidia-smi Thu Oct 13 10:46:02 2022 +-----------------------------------------------------------------------------+ | NVIDIA-SMI 515.65.01 Driver Version: 515.65.01 CUDA Version: 11.7 | |-------------------------------+----------------------+----------------------+ | GPU Name Persistence-M| Bus-Id Disp.A | Volatile Uncorr.
