Sorry this is so much later than i when i started this thread iv been busy finishing up everything for the year and to a degree advoiding this issue.
Iv gone to nvidia and used their drivers.
using the newest driver "6629" i had a few problems the first being during install when it was having problems cos the kernel source mandrake had installed at install was the 2.4 kernel while it was running the 2.6 kernel. Then i found i had to load the nvidia module my self using "modprobe nvidia". Once done and after editing the xorg config driver option "nv" to read "nvidia" i could "startx" without getting any errors but it come up with a blank screen and sticks there eventually breaking out in horizontal lines but never doing anyting helpful. This problem sounded like the same some other people have been complaining about on the nvidia forums the end of that was someone announcing that its a problem with the 6629 driver and it will be considered in the next driver release in the mean time to go back to using the previous driver "6111".
.....and so i have downloaded the 6111 driver but when i try and install this it errors out (during the installation as it builds the kernel module.
The ERROR is:
ERROR: Unable to build the NVIDIA kernel module.
I thought it may be older than the kernel i am using so i downloaded a version of the 6111 driver that was patched to use the 2.6 kernel but i get the same error in the same place.
Can anybody help me please.
By-the-way I am now using mandrake 10.1 official download.
I also tried to put windows XP on this computer to see if i could get the graphics card to work on that but after installing the cards drivers on XP and rebooting i get a blue screen of death at startup.
the rivafb module is detected. iv tried starting x both ignoring rivafb's existance and by "modprobe --remove rivafb" but either way the same black screen appears.
