Some further information from some investigations: Firstly, following up on the "time theory" above. It seems to occur at times xx:03:07, xx:08:07, xx:13:07, ... Ie, every five minutes at seven seconds past. This seems very regular.
Secondly, following the comment above, I had been previously running LibreOffice-Calc, but the problem persists after it was shut down. (Confirmed with a "ps -ef" command that there were no stray tasks. In any case, I would think that whatever LibreOffice does, gnome should not hang like this! -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1676304 Title: Gnome hanging at random times for 1 minute or so To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-session/+bug/1676304/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
