I decided to install LMDE2 on one of my computers and it was working flawlessly, but only before updating. While system was being updated, Preferences (with probably some other things) dissapeared. I don't know if it's important, but it won't hurt to point that. After reboot, when I want to log in, I get the "Your session lasted less than 10 seconds" information.
In .xsession-errors is this info:
Code: Select all
syndaemon: couldn't find any process (sorry if I translated it wrong from Polish) mdm: GLib-CRITICAL: g_key_file_free: assertion 'key_file != NULL' failed
ps. Intel GPU
