I am running FC10 with the latest nvidia drivers on a dell xps1530 laptop.

kmod-nvidia-2.6.27.9-159.fc10.i686-177.82-1.fc10.7.i686

Every 5 minites or so the display freezes for a few seconds. When I look in the Xorg.log I see the following messages.

Backtrace:

Can anyone tell me what I can do to solve this problem.

Nvidia has a linux driver for your card here. Just download the installer (.run file) and run it.

Alternaltely, did you try following the Nvidia driver guides at fedoraforum? It looks like it from the name of the package, but I've got to be sure, you may be missing a package that is needed for the card to work properly.

Yes, and I tried the rpmfusion install.
rpm -Uvh http://ftp-stud.hs-esslingen.de/pub/...ble.noarch.rpm http://ftp-stud.hs-esslingen.de/pub/...ble.noarch.rpm
yum install akmod-nvidia xorg-x11-drv-nvidia-libs.i386

However when I check what I have installed against what is on the nvidia site I see where I only have 177.xx drivers and nvidia site has 180.22, which was released on January 8th. When will an update one reach the rpmfusion repos.

Did you use nvidia-settings or nvidia-xconfig to configure your xorg.conf without letting livna-config-display do it's autoconfiguration first?

To fix this, run these two commands:

nvidia-config-display disable
nvidia-config-display enable

If that doesn't work than you may need to disable the drivers from making automatic changes to xorg.conf

livna-config-display --active off

I just installed the nvidia 180.22 drivers from the test rpmfusion repos and that seems to have fixed the problem. However I am interested in what you mention above. I have since two years used the livna repos version of the nvidia drivers and can't remember when last I would have run any video configs. Thus I expect that the livna config is the one that would have been run. Also, I recently moved to the rpmfusion repos and there I installed the akmod-nvidia package.

I must say however that I have been experinecing this problem for some months and am not sure at what point it started to occur. Do you think I need to revert to the 177.xx drivers and try the config stuff.

If the 180.22 update has solved your problem than I see no reason for you to revert back to the 177.xx, unless you want to use them for testing to solve the problem and provide information for others.

I'll try and revert in the coming week and see if the config options you suggested would affect the problem.

Thanks.
