Public bug reported: After updating from linux-image-5.15.0-71-generic, my machine failed to load the module properly and was only running minimal resolution in the desktop environment.
Part of journalctl -t kernel: Mai 30 19:22:44 iso-deskubuntu kernel: NVRM gpuInitOptimusSettings_IMPL: SBIOS did not acknowledge cfg space owner change Mai 30 19:22:44 iso-deskubuntu kernel: NVRM: Open nvidia.ko is only ready for use on Data Center GPUs.

I was also able to use -open again by creating a file with content "options nvidia NVreg_OpenRmEnableUnsupportedGpus=1" in /etc/modprobe.d/nvidia-open-unsupported-gpus.conf. ** Affects: linux-signed (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-signed in Ubuntu. https://bugs.launchpad.net/bugs/2021900 Title: Ubuntu 22.04 with Nvidia: linux-image-5.15.0-72-generic: [drm:nv_drm_load [nvidia_drm]] *ERROR* [nvidia-drm] [GPU ID 0x00000900] Failed to allocate NvKmsKapiDevice Status in linux-signed package in Ubuntu: New Bug description: After updating from linux-image-5.15.0-71-generic, my machine failed to load the module properly and was only running minimal resolution in the desktop environment.
