Ubuntu 18.04: Immediate logout after (graphical) logon
it seems to be a "once again" issue, but I really wasn't able to find anything useful for my case in the web.
Background:
I have a Lenovo Thinkpad T480, on which I installed Ubuntu 18.04 right after unpacking. The preinstalled Windows didn't even finish the installation/setup then. I bought it actually because it has switchable graphics (NVIDIA dedicated graphics and Intel integrated graphics), which allows me to run the 3D CAD (in a VMware VM with Windows) also when on the go.
I first didn't configure any power saving stuff at all, which led to a short battery runtime of maybe 1.5h or something. So about a month back, I installed tlp and also gave bumblebee a try, to make use of the Optimus feature (dynamic switching between integrated and dedicated graphics). This didn't work at all, the CAD could not use the 3D acceleration and resuming after suspend tended to crash the system or cause weird effects. One such weird effect was a USB port malfunction, so that the plugged-in mouse did not work anymore (no power). Integrated devices such as keyboard and touchpad still worked though. A reboot "fixed" the problem, so it probably is not hardware-related. I removed bumblebee shortly afterwards.
I usually completely reboot/turn off the notebook once in a few days, otherwise I just put it to sleep.
Problem:
A few days back, I shut down the notebook as usual. After booting it up next time to the login screen, the problem first appeared: I could enter my password, hit Enter and all that happens is the screen turning black, the mouse pointer is displayed near the lower right corner of the screen and after a second or so, I'm back at the login screen. No error message. At least once it also happened that the USB port problem described above showed up again.
It was always possible to login to a terminal (Ctrl+Alt+F2) without any trouble.
What I've tried:
Especially due to the mentioned USB problem, I suspected the graphics driver to have something to do with it. So I uninstalled all NVIDIA-related packages, but the problem remained the same. Reinstalling did not change anything either. I also tried to install and uninstall (with a few reboots) tlp and bumblebee, but none of them seem to change anything at all.
Booting into a previous kernel version did not help.
I went to a terminal and installed Xubuntu-desktop. Now, when I boot the computer, select a Xubuntu or Xfce session, then I can login to the graphical desktop and everything runs as well. Including 3D acceleration and NVIDIA-prime. This is true no matter if I use gdm3 or lightdm as display manager.
If I select any of the other sessions (GNOME classic, Ubuntu, Ubuntu on Wayland, etc.), the behavior is the same as before: Black screen, mouse pointer, sometimes a short flash of the desktop background image, then back at the login screen. Interestingly, if I now switch back to a Xubuntu session, the login fails there as well, with the same symptoms. Only after a reboot does such a login work again. Just on my last try, this led to apport coming up with a crash of light-locker:
light-locker crashed with signal 5 in g_type_create_instance()
Logs:
I really don't know where to look for errors. I've checked a few places:
- /var/log/Xorg.*.log: No errors (EE), nothing suspicous.
- ~/.xsession-errors: Last update is from a week back. A lot of errors are reported relating to tracker not being able to insert some metadata, as well as from the theme parser. At the end of the file, there are many such messages:
