Thanks for the suggestions. I upgraded my drivers to version 304.48 and the problem didn't go away. As a side note, I had to do it from the console, the graphical tool was giving me errors when trying to install the experimental package.
My impression is that some regression in mesa or a similar package that was recently updated is causing the slow graphic performances. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1066245 Title: Graphics some times runs very slow To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-nouveau/+bug/1066245/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
