mandrake 9.2 does it here: /etc/X11/xdm/Xservers and removing the nice -10 part of the command should be enough. > While we're on kernel 2.6, I've noticed something with the test releases: > whenever I try to install 2.6 through the contrib RPMs (test5, then test8) > I can never get NVIDIA to compile and install (using the method from > www.minion.de).

Chances are you're not loading the usb module correctly (some have changed names) or you're not mounting the new usbfs. Put this into your /etc/fstab : none /proc/bus/usb usbfs defaults 0 0 Cheers, Con
