Hi: I have just switched to Antergos from years of Ubuntu GNOME.
When upgraded to the latest Ubuntu version (17.10) (with GNOME as default DE) I started experiencing random session logout without being able to detect the cause. Then I rolled back to Ubuntu GNOME 16.04 LTS which had no such issue.
Now I switched to Antergos GNOME because I missed the features in the latest GNOME DE but still needed a stable working environment but surprise… random crashes all over again.
What happens is that the GNOME session freezes randomly, but mostly when a new application/window is about to open; then sometimes it restarts without any change but usually just crashes, logs me out, and then of course anything from the previous session is still alive after logging back in.
I am no such optimistic in expecting an immediate solution, but at least I hope someone has an explaination.
