I use GNOME 3.26.2 on an Asus Zenbook UX31E software is updated.
Every now and then the GNOME session would just close/crash and go back to GDM and I can logon again. It seems to me that it happens when the laptop is under “heavy load” which means a Java-app like JOSM is running, Firefox, Terminal, Libre Office. Or Just Firefox with 5+ tabs with HTML5 videos like Youtube in each one.
If it happens again: which logs do you need in order to help me?
