Hello everybody, This bug still exists. It happens on several of my systems (sysop @ university).
My test system: HP Compaq 8200 Elite CMT (hardware spec: http://h20564.www2.hp.com/hpsc/doc/public/display?docId=emr_na-c02779501) with an extra video-card: Geforce 7300 GS I've tried nouveau and proprietary drivers. I'm running Ubuntu 14.04.2. Packages are as up-2-date as they're going to get. uname -a: Linux HOSTNAME 3.13.0-55-generic #92-Ubuntu SMP Sun Jun 14 18:32:20 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux We use lightdm, but light-locker is removed, because it causes trouble on other fronts. We also offer a multitude of WM's to our users, with all the trouble that causes :(. We've installed ubuntu-desktop, xubuntu- desktop, kde-workspace, gnome(classic), i3-wm, XMonad, Openbox. Most of our systems have very similar hardware, they're all HP Compaq systems (some a bit older, some newer). The trouble seems to be with the older NVIDIA card, because that's the same on all the troublesome systems. The fix Eloy Paris mentioned in comment #14 is the only thing so far that resolves the issue. Thankfully we use Puppet to manage our workstations, so implementing it wasn't too difficult, but I would very much like to see a more permanent solution. -- You received this bug notification because you are a member of compiz packagers, which is subscribed to compiz in Ubuntu. https://bugs.launchpad.net/bugs/1424013 Title: Compiz high CPU and UI freeze on NVIDIA after fix for #269904 in trusty-updates To manage notifications about this bug go to: https://bugs.launchpad.net/compiz/+bug/1424013/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~compiz Post to : compiz@lists.launchpad.net Unsubscribe : https://launchpad.net/~compiz More help : https://help.launchpad.net/ListHelp
