I updated my TW laptop yesterday to TW20221012. After that, X does not start anymore. The laptop has an NVIDIA optimus card, GM108M [GeForce 940MX], I'm using the G05 series of drivers from the nvidia repo. The modules built w/o issues, and are loaded. But journalctl tells me
kernel: [drm:nv_drm_load [nvidia_drm]] *ERROR* [nvidia-drm] [GPU ID 0x00000200] Failed to allocate NvKmsKapiDevice kernel: [drm:nv_drm_probe_devices [nvidia_drm]] *ERROR* [nvidia-drm] [GPU ID 0x00000200] Failed to register device
and as a consequence X won't start (from Xorg.0.log) (EE) NVIDIA(GPU-0): Failed to initialize the NVIDIA GPU at PCI:2:0:0.
Hmm. Works for me with G05/Kernel 6.0 on a Quadro Kepler card without any issues.
So I also DUPed my home machine with GeForce GTX 980 and the same G05 driver suite from the nvidia repo. No problems with that. So I somehow suspect it has to do with the Optimus chip?
