Having had the issue with 14.04, 15.04 and 15.10 (also on fresh installed system). Only propretary driver installed is bcmwl-kernel-source, no other system modifications were done (graphics are Intel HD).
Problem also happens with disabled Firefox addons and doesn't not happen at all without running Firefox (I cannot confirm it with Thunderbird). - No mouse cursor available when screen is frozen - ctrl-alt-f2/f3/etc don't work - Caps lock is not blinking (so no kernel panic?) --> shutdown with powerbutton is necessary At the moment it is not possible to use Firefox, Midori is a ok solution. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1432492 Title: Firefox and Thunderbird freezes entire system after a few seconds of use To manage notifications about this bug go to: https://bugs.launchpad.net/firefox/+bug/1432492/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
