To clarify: it's a Logitech headset (with microphone) connected by USB and a secondary display connected by HDMI.
The laptop boots normally until it reaches the login screen. I enter my password, the screen changes, blips, then I'm back at the login screen again. This cycle repeats as long as I'm willing to type in my password and hit enter. This last time I dropped to shell (ctrl-alt-f1) and removed lightdm. I did fail to stop it, however, and that caused "post-removal script returned error exit status 1" because it couldn't remove the user 'lightdm' (it was still in use in the other terminal). This is related to user error. The real problem that created this scenario seems to exist somewhere else. For that problem, I was able to boot normally by removing the HDMI jack and the USB jack from my laptop. Dunno if any of that helps anyone, but I hope so. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1249407 Title: package lightdm 1.8.4-0ubuntu1 failed to install/upgrade: subprocess installed post-removal script returned error exit status 1 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/lightdm/+bug/1249407/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
