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 Kernel Packages, which is subscribed to nvidia-graphics-drivers-470 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 Status in Mutter: Unknown Status in linux package in Ubuntu: Confirmed Status in mutter package in Ubuntu: Opinion Status in nvidia-graphics-drivers-470 package in Ubuntu: Confirmed Bug description: I recently upgraded my NVidia drivers on my ThinkPad P1 Gen 3. If I start Ubuntu on Wayland session and plug in my USB-C monitor the system reliably completely freeze. The freeze is also reproducible if the screen is plugged in during startup and trying to login into a Wayland session. Only Wayland session experiences a crash. The crash happens ONLY if the USB-C monitor is plugged in. USB-C monitor is also a USB3 hub. Hardware seems to work fine, as Windows shows no issues with the setup.
