Completly remove the driver, run ldconfig restart the machine. Use the ""Provided"' Open Source kernel drives for your video card. Simple Solution. ***OR*** > On Thu, Apr 3, 2008 at 10:58 AM, John J.

This maybe the brunt of your problems of not have the newest driver. It may contain the fixes for your problem. Drivers from third party sites are modified to there liking, so keep that in mind. Window's WHQL Certified drivers had this problem with the nividia card and a fix in the latest drivers corrects this issue. 1. Only other idea is if the "LATEST" driver want correct the problem, then the only choice is to use the open source drivers in the kernel. IE, remove the driver completly from Nvidia. 2. Next choice is to wrestle with DKMS and install the nvidia dkms driver from one of the other Repositories. Anyone on the List know of a good DKMS tutorial besides the one at linux.dell.com? Relating to drivers? I do not want bits and pieces, I need reliable facts
