I just experienced the same issue on 18.04, after upgrading to 4.15.0-45-generic and rebooting, gdm hung after logging in, I had this issue when trying to log in to tty as described here. I found if I didn't type a username, the cursor returned and i could type again, if I entered a username it continually entered newlines until I did a ctrl-c.
I had to revert back to 4.15.0-43-generic in order to log in to either gdm or tty (when I tried 4.15.0-44-generic it just hung before gdm finished loading) I am using a Lenovo P51s -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1815122 Title: Unable to login via tty To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1815122/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
