After deleting the .Xauthority file, I can now successfully log into a Unity session.
The problem seems to be gone (rebooting worked fine after this). Maybe somebody can figure out how I got into this situation, but otherwise the bug can be closed as far as I'm concerned. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xorg-server in Ubuntu. https://bugs.launchpad.net/bugs/1641055 Title: startx, lightdm fail to start Status in xorg-server package in Ubuntu: New Bug description: After updating from 16.04 to 16.10, lightdm doesn't start. Adding 'nomodeset' for booting allows it to start, but apparently lacks all acceleration. Trying different kernels doesn't help, including the one from 16.04. Sorry for brevity, I'm writing this on my phone...
