Hello, This is a question out of ignorance. ;-( I had big troubles after installation of the NVidia 4496 driver (black screens). After a lot of trial and error, I have found out that disabling AGP (Option "NvAGP" "0") solved the black-screen problem. So far so good, but now I still have the problem of multicoloured garbled screens when going from X to a console with CTRL-ALT-F1 .. F2 .. etc.
Now I'm wondering if disabling AGP could have something to do with it, but I can't enable it (I will get the black screens again).
In the Nvidia README, I saw a paragraph on AGP which says : --- QUOTE -------------- To use the Linux AGPGART module, it will need to be compiled with your kernel, either statically linked in, or built as a module. NVIDIA AGP support cannot be used if AGPGART is loaded in the kernel. It's recommended that you compile AGPGART as a module and make sure that it is not loaded when trying to use NVIDIA AGP. --- UNQUOTE -------------
My question is : How can I check if AGPGART is compiled as a module in my standard SuSE 8.2, and how can I make sure that it is not loaded (and how can I see whether it is loaded or not) ? // CUT
Check if agpgart.o is in /lib/modules/`kernel-version`/kernel/drivers/char/agp. Yes, it is. So, I presume that it is compiled as a module. Correct ?
You can see if the module is loaded by viewing the output of 'lsmod' and looking for agpgart lsmod shows no agpgart, so it is not loaded !? Would that be because of the Option "NvAGP" "0" in my XF86Config (see above), or could something else be wrong here ? I still don't know how I can control loading of agpgart.
Anyway, specifying Option "NvAGP" "1" (= use NVAGP) leads to a black screen. Specifying Option "NvAGP" "2" (= use AGPGART) also leads to a black screen. Mysterious, isn't it ? Cheers, -- Jan Elders Nuenen the Netherlands
