Another UPDATE: I now discovered that there are two types of freezes: The first one is what I mentioned before: complete system freeze, no mouse move, music lags and ends some seconds later. But I now had some freezes (more rare) that didn't affect the music. I couldn't change to the virtual consoles, but I was able to access the computer via ssh. I'll try that with the next freezes too.
And it's absolutely clear now that it's not a java bug. I got it also with Games on wine and rarely also without playing games (When desktop effects of Unity apperared or when i clicked onto notifications of Opera Next). Btw: I'd be glad to be able to help fixing the bug, I have some basic knowledge of C/C++. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/999109 Title: complete freeze of Ubuntu after some time using Java To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-nouveau/+bug/999109/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
