AGP: disabled
Hi all,

so... i have a problem (of course ;)) : my agp is disabled :mad: My card is a GeForce3 Ti200 (128M) and my motherboard, an ABIT KT7A (chipset KT133). My dristribution is a Debian and my XFree version is 4.2.1.
I have disabled (no module, no static) agpgart in my kernel. My module configuration:
alias /dev/nvidia* nvidia
alias char-major-195 nvidia

(i tried to add :
options nvidia NVreg_ReqAGPRate=2
options nvidia NVreg_EnableVia4x=1
but no effect)

Extract from my XF86Config-4:
Section "Device"
Identifier "Generic Video Card"
Driver "nvidia"
Option "UseFBDev" "true"
Option "NoLogo" "true"
Option "NvAgp" "1"
Option "RenderAccel" "true"
Option "PageFlip" "true"

:~$ cat /proc/driver/nvidia/agp/status
Status: Disabled

~$ cat /proc/driver/nvidia/agp/host-bridge

What i missed ? Any suggestions ?

Best regards,

This problem sounds very similar to mine (still unresolved), which nvidia drivers are you running?

I just found this, as well: http://www.nvnews.net/vbulletin/show...s+disabled+agp
If you can't be bothered reading it: add try_unsupported as an option to the agpgart driver.

agp_try_unsupported only works with the agpgart driver.

I'm not positive whether the nvagp driver contains support for the KTxxx series chipsets, though. I know some have had trouble with the KT400, and I think some others have had trouble with the KT333 (which is just a KT266 with a faster memory bus), but I could be wrong on that. I have a KT333, and it works just fine with agpgart (kernel 2.4.19 with the -preempt patchset).

Why did you disable agpgart? Does enabling it (and recompiling the kernel, obviously -- if you make it a module, you may have to do something like post-install nvidia /sbin/modprobe -k agpgart and pre-remove nvidia /sbin/modprobe -r agpgart in your modules.conf to get the module to load when it's needed, though) help?
