Comment 37 for bug 1424013

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.
