Public bug reported: After having problems with the nvidia driver 470, I reverted to the nouveau driver, only to find that using suspend or shutdown in the XFCE4 menu just returned to the login page. However, I found that using the 'shutdown' or 'pm-suspend' commands worked OK.
Checking syslog after a failed suspend lead me to /etc/systemd/system directory: lrwxrwxrwx 1 root root 9 Aug 25 15:04 nvidia-hibernate.service -> /dev/null lrwxrwxrwx 1 root root 9 Aug 25 15:04 nvidia-resume.service -> /dev/null lrwxrwxrwx 1 root root 9 Aug 25 15:04 nvidia-suspend.service -> /dev/null Also, there were two directories containing links to the above 'masked' services. Deleting those links restored suspend and shutdown functionality. drwxr-xr-x 2 root root 4096 Aug 26 18:14 systemd-hibernate.service.requires/ drwxr-xr-x 2 root root 4096 Aug 26 18:08 systemd-suspend.service.requires/ Obviously a problem in removing all the nvidia settings. ** Affects: software-properties (Ubuntu) Importance: Undecided Status: New ** Tags: 20.04.2 software-properties xubuntu ** Tags added: 20.04.2 software-properties xubuntu -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1941932 Title: Reverting to nouveau driver leaves dead nvidia links causing suspend and shutdown to fail To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/software-properties/+bug/1941932/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
