After upgrading to 14.10 tonight, I noticed a slowdown especially while using totem. I was getting about 0.2 frames per second using totem. VLC appeared to run but was choppy at larger resolutions. Other than totem, the primary symptom was sluggishness. It took 1 second for gnome-shell to react to selecting and dragging a gnome- terminal that was in the background behind chrome. After the upgrade, the kernel appeared to be running the i915 module (as seen by lshw -c video). ibus-gtk was already installed, so it wasn't that either. Then I installed the edger's xserver ppa. This helped both gnome-shell and totem, considerably. Videos actually ran for a second or two at a time, but were still choppy in totem. What appeared to be happening was that gnome-shell would spike the cpu going to 80% when totem was running. Gnome-shell was more responsive but still sluggish using the edgers xserver. Dragging a gnome-terminal in the background still took around a second for gnome to respond. Then I installed gnome-staging ppa. This helped the most, eliminating the gnome-shell cpu spike while playing totem, and making the windows much more responsive including dragging a gnome-terminal that was in the background. So it looked like both things helped to varying degrees. I got a better totem frame rate using the edgers x server. But gnome-staging gave me a better gnome-shell performance. -- 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/1386721 Title: Graphics Slow After Upgrade 14.04 - 14.10 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1386721/+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
