Annoyingly my NVIDIA installation from RPM-Fusion is (again) not working.
I noticed (under GNOME) that my system is not using the NVIDIA driver at all.
I first noticed on Fedora 30 so I uninstalled NVIDIA, upgraded to Fedora 31, reinstalled NVIDIA - but still nothing.
My System is a XPS 15 9550 with the internal Intel GPU and an additional GTX 950M.
Output of some commands:
$ glxinfo | grep vendor server glx vendor string: SGI client glx vendor string: Mesa Project and SGI OpenGL vendor string: Intel Open Source Technology Center $ DRI_PRIME=1 glxinfo | grep vendor libGL error: failed to create dri screen libGL error: failed to load driver: nouveau server glx vendor string: SGI client glx vendor string: Mesa Project and SGI OpenGL vendor string: Intel Open Source Technology Center $ lsmod | grep nvidia nvidia_drm 57344 4 nvidia_modeset 1118208 3 nvidia_drm nvidia_uvm 1081344 0 nvidia 19980288 135 nvidia_uvm,nvidia_modeset ipmi_msghandler 73728 2 ipmi_devintf,nvidia drm_kms_helper 212992 2 nvidia_drm,i915 drm 512000 12 drm_kms_helper,nvidia_drm,i915 $ cat /proc/cmdline BOOT_IMAGE=(hd0,gpt2)/vmlinuz-5.3.11-300.fc31.x86_64 root=/dev/mapper/fedora-root ro resume=/dev/mapper/fedora-swap rd.lvm.lv=fedora/root rd.lvm.lv=fedora/swap rhgb quiet rd.driver.blacklist=nouveau modprobe.blacklist=nouveau nvidia-drm.modeset=1```
I might add that i just noticed this one day, before that GNOME used the NVIDIA driver as expected.
Nvidia drivers are loaded, but Intel gets used
Maybe there is someone that has a hunch what could cause gnome to refuse using the NVIDIA driver.
