Dear Maintainer, *** Reporter, please consider answering these questions, where appropriate *** Noticed since upgrade of nvidia-driver v.470.74-1. SDDM crashes, cannot login as usual. Messages in /var/log/message shows: nvidia-uvm: Loaded the UVM driver, major device number 237. sddm[996]: Error from greeter session: "Process crashed" sddm[996]: Auth: sddm-helper crashed (exit code 15) sddm[996]: Error from greeter session: "Process crashed" sddm[996]: Auth: sddm-helper exited with 15 Stopping sddm and using startx to start X session works fine. Purging nvidia-driver and using nouveau results in sddm starting as usual. Using gdm3 instead of sddm works properly. *** End of the template - remove these template lines ***
