FWIW, but I'm also experiencing the issue and I recall reading (I can't remember where) that the Thunderbolt port on the left end of my laptop is directly wired to the NVIDIA GPU, even when Optimus is enabled. This is not the case for other USB-C ports on my laptop. This seems to be verified by the fact that, on X11, attaching a display to the Thunderbolt port also makes it show up in the NVIDIA control panel, which shows a reduced view and feature set - because it is acting as secondary GPU. The main laptop display is also not shown there, as it is being handled by the Intel GPU. -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to mutter in Ubuntu. https://bugs.launchpad.net/bugs/1960865 Title: System freeze when plugging USB-C monitor into a hybrid Intel/Nvidia laptop: [drm:__nv_drm_gem_nvkms_memory_prime_get_sg_table [nvidia_drm]] *ERROR* [nvidia-drm] [GPU ID 0x00000100] Failed to get memory pages for NvKmsKapiMemory To manage notifications about this bug go to: https://bugs.launchpad.net/mutter/+bug/1960865/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
