Here is a review of Fedora Core 3 running on a laptop:

From the article:
-=-=-=-=-=-=- Inside that file I learned I must edit this file:
/etc/security/console.perms
In particular, console.perms contains the following line which needs to be deleted:
=/dev/nvidia* /dev/3dfx*
Finally, I needed to issue the following commands:
chmod 0666 /dev/nvidia* chown root /dev/nvidia*
-=-=-=-=-=-=-
That's wrong. console.perms is the right way to do it. You don't want 666 permissions on a device node.
Maybe the perms in console.perms are incorrect (tuxracer worked perfectly for me in gnome - don't know why kde would be any different) but taking it out of console.perms and chmod 0666 may work but is wrong.
