Happened to me again, this time by opening a file with Calc and with the latest Kernel (3.19.0-27-generic #29~14.04.1-Ubuntu SMP Sun Aug 16 01:51:13 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux). When I tried to close the application, the system froze again and I had to hard-shutdown it. Again, it was an "angry" nouveau driver.
This is becoming a real issue, as it basically renders the usage of LibreOffice impossible. But: it seems to be a Kernel problem which needs to be resolved by kernel package. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1481129 Title: System freeze when using Libre Office To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1481129/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
