We should not be crashing 3-4 times per hour.
3-4 times a day for me. Here are some bugs, they're in the Red Hat bugzilla because they were filed with Fedora Abrt. These hardly represent the number of crashes though, because nearly always "the backtrace isn't usable". https://bugzilla.redhat.com/show_bug.cgi?id=791130 https://bugzilla.redhat.com/show_bug.cgi?id=809365 FWIW on some of my machines, the screensaver is already pretty funny security-wise. When coming back from sleep. It shows the desktop screen for several seconds before locking the screen. Sometimes it only locks one monitor. Sometimes the lock dialog isn't visible. I haven't started to try and debug these issues. I guess one way of looking at that is that hopefully the Lock screen refresh will solve some of these problems :P Cheers, Stef _______________________________________________ desktop-devel-list mailing list [email protected] http://mail.gnome.org/mailman/listinfo/desktop-devel-list
