I forgot to mention my system settings - I'm using Thinkpad T420 with Nvidia Optimus. I am *not* using nvidia-prime, as that setup didn't work for me, instead I'm using the bumblebee setup where X is configured only for the Intel graphics, and bumblebee is using a second X server to render 3D games.
I have the Nvidia binary driver 331-updates from canonical installed, and not nouveou. I'm not using an xorg.conf, but if I try to generate one using 'X -configure', the generated file includes only the Intel setup. At the times of the problem, the bumblebee setup is not being used and the nvidia driver is not even loaded, but bumblbeed is running. -- 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/1306470 Title: Under KDE, X consumes 100% CPU after returning from VT switch To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1306470/+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
