Same problem on DELL laptop with NVIDIA Corporation G98M [Quadro NVS 160M] (rev a1) connected to docking station with external (1920*1200) monitor.
It starts to get hotter at my workplace with the summer nearby and GPU temperature seems to go up to 80+°C Once this happens the whole X session slows down and all applications start to take more CPU. I have the impression the graphics card somehow throttles down to almost unusable speed. A workaround for me is to install a big fan that continuously blows on my laptop causing temperatures to go down again. Disabling the second screen also brings back temperatures to a normal level (and powermizer to level 0 where it stays at 2-3 with the extra monitor) I'll try purging and reinstalling the driver... -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to nvidia-graphics-drivers in Ubuntu. https://bugs.launchpad.net/bugs/877438 Title: [8xxx] Unity/compiz has sluggish performance on dual-head with nvidia driver To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/compiz/+bug/877438/+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
