[Bug 1424013] Re: Compiz high CPU and UI freeze on NVIDIA after fix for #269904 in trusty-updates


Hello everybody,

This bug still exists. It happens on several of my systems (sysop @

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

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-

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

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.
