My observation, it happens typically when i do something on google particularly gmail. I don't recall anything like that happening in calendar, docs or youtube. To my observation, no other sites in my experience have this (hang condition) problem.
At times, i can do a force quit. In that case, i usually logout & login again just to restart X. If it is a complete hang, & that happens periodically, at least 1ce a day, the power button does work for me, but you chaps are right, ctrl-alt whatever, not even f1-f4 work; so that i can at least do a clean shutdown. The system is completely hung. Here's my system info; Acer aspire 4755g intel core i5-2410M NVIDIA GeForce 540M Mem : 8gb Firefox 33 Ubuntu 14.04.1 I followed this proc to install bublebee. Dono if i did something right/wrong, but at that time, it worked. I would say it started happening about 2wk to a month ago soon after i did an update. http://coffeecup83.blogspot.sg/2013/04/ubuntu-1304-nvidia-optimus-bumblebee.html personally, i'm not really sure it's a firefox problem since it only happens on google & in particualr gmail! -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1318403 Title: Firefox continuously freezes and freezes the rest of the system (Ubuntu 14.04) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/firefox/+bug/1318403/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
