Thanks for all the responses. I am begining to understand the roles of the various module files.
For the moment I inserted the line alias char-major-195 NVdriver in the file /etc/modutils/aliases and then ran modconf so the line is now included in /etc/modules.conf. With this change xdm runs successfully at bootup. I dont know why my initial installation was incomplete. I created a directory /usr/local/nvidia and downloaded NVIDIA_GLX-1.0-3123.tar.gz and NVIDIA_kernel-1.0-3123.tar.gz into this directory. I unpacked each of these and ran make install in the subdirectories they created. Both compilations completed successfully. After this insmod NVdrivers worked but I had to run it after each bootup and then restart xdm. If I missed something in this sequence I would appreciate knowing what I should have done. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble?
