My PC was working yesterday without any problem. I shut it down and tried to open this morning. It prints out these messages on the black screen:
systemd-udevd: failed to execute '/bin/systemctl' '/bin/systemctl start --no-block nvidia-persistenced.service': No such file or directory systemd-udevd: failed to execute '/bin/systemctl' '/bin/systemctl stop--no-block nvidia-persistenced': No such file or directory
It then continued with the login screen. I entered my password and pressed enter. It waited for a while and the login screen reappeared again.
How can I fix the problem?
