You _must_disable_ DRI if you load the nVidia driver! nVidia does _not_ use the Direct Rendering Infrastructure (DRI) for OpenGL, it provides a full OpenGL over X11 (GLX) capabilities! [ Think of DRI v. GLX as the old "Mini Client Driver" (MCD) v. the full "Installable Client Driver" (ICD) support for OpenGL in the Windows world. Having a full GLX implementation is better, long story. ] Comment out the line Module "DRI" near the top of your XF86config/Xorg configuration file. The DRI section at the end will be ignored (don't worry about commenting it out). > Neither of those two files is found on my laptop in /dev. > Is this because of udev? On FC3+/RHEL4+, yes. There are many "proper" ways to set this up. This is the easiest way although not the most "proper" (just copy the dev files to /etc/udev/devices/) ... 1. Re-install the nVidia driver (creates /dev/ entries) 2. Run: cp -a /dev/nvidia* /etc/udev/devices chown root.root /etc/udev/devices/nvidia* Jim Perrin <jperrin at gmail.com> wrote: > No, /dev/nvidia0 exists on my centos 4.2 box in /dev > You should check that you have nvidia's drivers installed > correctly and that the nvidia module is loaded by checking > with lsmod. udev is the culprit. > I think xdpyinfo gives you this. I can't remember. xvidtune But open your monitor's manual and get the maximum specs for your monitor and set them in the XF86Config/Xorg file first. -- Bryan J.
