Please try this: 1. Don't log in, so the system doesn't lock up. 2. Switch to a VT (e.g. Ctrl+Alt+F4) and log in. 3. List your nvidia-related packages (dpkg -l | grep nvidia) and paste them here.
Furthermore, if you have a working internet connection that is on without needing to log in then please also run this in the VT: 4. apport-collect 1708608 5. If you skipped step 4, then please try plugging in an ethernet cable, reboot and retry step 4. ** Changed in: gdm3 (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gdm3 in Ubuntu. https://bugs.launchpad.net/bugs/1708608 Title: Cant login to any session in Ubuntu 17.10 (desktop hard locks) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gdm3/+bug/1708608/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
