I am using the Mint Gloria with Gnome. The system is on the newest update level. After some minutes with Firefox or Opera the browsers end without any message. The browsers are doing in this way for about two days. In which log-file I could find a hint for this disappearing?
The first time a normal user session ended abrupt. The user-login started with login-page.
I think there is a link between these two sorts of crashes?
in messages I found these errors:
