I did check, but there were not really good clues in the logs, among other things because it seemed that ~/.xsession-errors did not get updated. ls did report that ~/.xsession-errors belongs to me, but it still didn't update it, which is why I then removed it. But I only did that after removing gdm as well, so I don't know whether removing gdm or removing ~/.xsession-errors or both fixed it. Checking the logs again, I have only this interesting line: >Nov 29 04:24:26 localhost gdm: GdmDisplay: Session never registered, failing > Did you reboot after reconfiguring? I had selected the older system generation in the grub boot menu.
