Nvidia agp -vs- agpgart

munkie_poo · 09-16-2005, 09:20 AM

I have and AMD system with a VIA mainboard (VT8377 [KT400/KT600 AGP]) and AGP Nvidia Geforce FX5200 (module 1.0-7167), running a newly updated Slack 10.2

Im trying to get the Nvidia agp module to load instead of the agpgart module without much success.

in /etc/X11/xorg.conf Ive added:
Option "NvAgp" "1"

Firstly a quick question of what modules should/shouldn't be getting loaded?

I dont want agpgart?

Do I need via_agp?

what is the nvidia agp driver called? I found a nvidia_agp, but i found somewhere mentioned an nv_agp.

Im in the middle of compiling a new kernel with agpart disabled, to see if this will work as I couldn't find a way to prevent AGPGART from loading. BUT Im unsure of what should be loaded.

any help would be great.

Thanks

OK, Kernel compiled wihout agpgart, and a few optimisations.

When I rebooted and tried to install the nvidia driver again, I recieved an error and told to read the nvidia-installer.log, this was just pattering on about 'invalid things which means no sense in something.h'

I updated the Nvidia driver and the newer one installed fine, but mentioned an iffy previous installation and would try as hard as it can to remove the old one... and it did

I then 'init 4' welcome back to KDE...It works .....so far

glxgears show fps greather than 1500

glxinfo shows 'direct rendering: yes'

but no sign of any agp in 'lsmod', now is that a good thing or a bad thing?

Nvidia install instructions are pretty much straight forward, and there are several threads from the past month and a half how users got their drivers working. You just need to search them out.

From what I could learn from googling, via chipsets for full 8x agpgart are not supported in 2.4.x kernels (unless this has changed recently), but are in 2.6.x. Mine has been working fine since compiling to 2.6.10.

Find the README for the Nvidia driver, it will put your mind at rest.

in 10.1 i use nvagp instead of agpgart, i disable agpart module on rc.modules then add use option nvapg "1" on xorg.conf and it work perfect but on 10.2 and using kernel 2.6.13 when i use dmesg it says that nvidia module taint kernel, and when i use cat /proc/driver/nvidia/agp/status it says agp disabled. is there any way i can disable agpgart without compiling kernel?

"tainting the kernel" just means you've added a proprietary driver. Don't worry about it.
