Public bug reported:

I did a standard dist-upgrade from jaunty to karmic.
I have a nvidia graphic card and was using the standard proprietary drivers (proposed by jockey-gtk), and with desktop effects activated.

Since the upgrade, I experience freezes that seem to be related to this
proprietary driver :

- whenever I hibernate the PC, and start it again, the boot seems fine, but the screen stays blank after the resume
- the system freezes after a few minutes watching any flash video content (with the proprietary flash)

I'm using version 185.18.36-0ubuntu9 of nvidia-glx-185.
Both problems are solved if I disable this proprietary driver through jockey-gtk.

I ran two tests :
- upgrade to version 190.42 of the drivers (by adding the ppa deb http://ppa.launchpad.net/nvidia-vdpau/ppa/ubuntu karmic main
)
- keep version 185.18.36 and disable desktop effects
In both cases, the freezes are still there.
The only workaround I found to avoid them was to disable the proprietary driver

I found this bug : https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers-180/+bug/474917 but it does not seem to be a duplicate, as my dkms status reports :
nvidia, 185.18.36, 2.6.31-14-generic, i686: installed

I did not find anything relevant in /var/log about these freezes
