When connecting my RTX 3060 eGPU, X.Org freezes. After restarting GDM3 via SSH the system becomes responsive again and I was able to check dmesg and found this error:
kernel: [drm:__nv_drm_gem_nvkms_memory_prime_get_sg_table [nvidia_drm]] *ERROR* [nvidia-drm] [GPU ID 0x00000800] Failed to get memory pages for NvKmsKapiMemory 0x000000004d89f1a4
I was unable to upload the nvidia-bug-report.log on the forums, so I have linked in below:
