Everyone, I have two Dell Laptops both had problems with FC3, Nvidia 6629 and the UXGA LCD. One has a GeForce 3 and the other a GeForce 4. When using the LCD with the 6629 driver X launches but the screen is disrupted and has an offset image with colored stripes on the right side and bottom. The solution: Unpack the Nvidia source #./NVIDIA-Linux-x86-1.0-6629-pkg1.run -x Change to the Nvidia source directory #NVIDIA-Linux-x86-1.0-6629-pkg1/usr/src/nv/ Edit the file os-registry.c # vi os-registry.c Locate line 290 where it says: static int NVreg_Mobile = ~0; and change it to: static int NVreg_Mobile = 0; Change to the NVIDIA-Linux-x86-1.0-6629-pkg1 directory #cd ../../../ and rerun the installer #./nvidia-installer Don't forget to copy the Nvidia files from /dev/ to /etc/udev/devices/ #cp -a /dev/nvidia* /etc/udev/devices Hope this works for anyone else who's having trouble. Best, Steve
