Haha, i just wanted to make a PSA Thread about that. I had the same problem today. After upgrading with pacman -Syu, nvidia-dkms and other packages upgraded to lastest version. And what already maked me curious that i didnt saw in the upgrade process that he rebuilded the dkms modules to the new version. First i thought i simply missed the output and restarted. And voila. No X and so no Desktop. Quick log reading showed me that he was still trying to load the old builded kernel modules and crashed with the Output: > NVRM: API mismatch: the client has the version 495.46, but > NVRM: this kernel module has the version 495.44. Please > NVRM: make sure that this kernel module and all NVIDIA driver > NVRM: components have the same version. The simple fix was to rebuild the dkms modules with simply force reinstall nvidia-dkms. ---

solution to login in Xfce with mate add these option “systemd.unified\_cgroup\_hierarchy=true” if not on login GUI , this is a root process Xorg running that can be used for User login ---
