I applied the procedure described there: https://bugs.launchpad.net/ubuntu/+source/gnome- shell/+bug/1751101/comments/7
I start Ubuntu 17.10 I start Firefox 58.0.2 I press F11 for more than 2 seconds I wait for 35 minutes I press on AltGr+PrintScreen+S just to be sure data is written on disk I wait for several seconds I reboot with AltGr+PrintScreen+B There is nothing in /var/crash/ I feel a bit frustrated after all that time spent trying to obtain the data you need. Daniel, you told it wasn't a good idea to ask you to reproduce the problem, but I still think this would be a good solution to get valuable data on your side. I understand this may expose a different bug, but with some chance, that other bug will be related to this one. At worst you could open another ticket with the data you collected and link the two tickets. Maybe you don't have time, or won't be able to reproduce the problem, so I can also wait for Ubuntu 18.04 and try to reproduce it again. You told me there are many gnome-shell crashes at the moment, so maybe one of the fix that will ship with 18.04 will help with this bug. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1749779 Title: System freeze when going back and forth fullscreen mode with Firefox To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1749779/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
