Try using NVIDIAs package instead. Their install is really quite well behaved. I got both my NVIDIA machines up and running first time and the acceleration is there. I'm looking at glmatrix on my 1Mhz PIII GForce2 machine now and it is slick... Here's my kernel upgrade process for them. 1) Install new kernel, kernel source, etc. using your favorite installer (yum in my case). 2) edit /etc/inittab to set default runlevel to 3 3) 'shutdown -r now' 4) logon as root (or login and 'su -' to root) 5) 'sh NVIDIA-Linux-x86-1.0-5336-pkg1.run' and follow the prompts. Let the installer remove the old driver, look for a new module locally, via FTP and finally if necessary, let it make a new one for you. It compiles everything up and installs it with a minimum of muss & fuss. If you were already running the NVIDIA drivers, then your XF86Config is still valid for it. After the installer finishes successfully, edit /etc/inittab again to reset the default runlevel back to 5. After that you can either reboot, or simply issue 'init 5'. Mind that if you do the latter, you will still have a root session open on the Alt-F1 console. After the X logon screen comes up, press Alt-F1 to get back to that console and log off. Then press Alt-F7 to switch back to the X logon. BTW, One of my machines is that PIII I mentioned, the other is an Athlon XP 2000+ with a GForce4. Like I said, both converted to the new kernel just fine after the installer made a new module. HTH Eric Diamond eDiamond Networking & Security 303-246-9555 eric@xxxxxxxxxxxx
