I am running Manjaro 25.0.0 on Kernel x86_64 Linux 6.675-Manjaro. I have my system configured to run XFCE. The system boots to the login screen but after entering credentials, goes black and come back to the login screen.
When I log in through ssh or a local tty, the only thing I see in .xsession-errors is:
Environment variable $DISPLAY not set, ignoring.
Environment variable $XAUTHORITY not set, ignoring.
I haven’t changed anything since the last time I booted other than running a full system upgrade.
I am guessing that the display manager isn’t starting up. Good guess? What to look for? How to fix?
Check if there is enough space after upgrading your system. Lightdm (Login-Manager) on XFCE don’t like not having space on the root file system: Free up space.
I am a dope. And I have a bad memory. I ran into a problem like this before and completely spaced on it. It is a problem with my VNC setup, which I thought I fixed oh so many months ago.
