I had to revert back to the patched 4363 driver availabe from www.minion.de
The harderst part for me was the fact that I am running ubuntu and one of their 22.214.171.124-4 kernels. So for those of you running Linux on the Toshiba Satellite Pro 6100, I had to do this:
Download the patched driver from www.minion.de
and run that.
I then had to add the following script to /etc/init.d:
#Create NVidia Devices
mknod -m 660 /dev/nvidia0 c 195 0
mknod -m 660 /dev/nvidia1 c 195 1
mknod -m 660 /dev/nvidia2 c 195 2
mknod -m 660 /dev/nvidia3 c 195 3
mknod -m 660 /dev/nvidia4 c 195 4
mknod -m 660 /dev/nvidia5 c 195 5
mknod -m 660 /dev/nvidia6 c 195 6
mknod -m 660 /dev/nvidia7 c 195 7
mknod -m 660 /dev/nvidiactl c 195 255
chgrp video /dev/nvidia*
Which is pretty much what the above posts all say, except that I had to do a chgrp on the /dev/nvidia* files so that the gl stuff would run once X started.
The reason i had to go back to the 4363 driver was that the switching down to a console from X produced a garbled screen. Otherwise, the 5336 driver worked fine as well.
I could not get the resolution beyond 1400x1050 nor could I get any of the 6series drivers to work without getting the split window.
