Hmmm, I hadn't thought to check the AGP status. I found that forcing
NvAGP with:
Option "NvAGP" "1"
results in:
$ cat /proc/driver/nvidia/agp/status
Status: Disabled
and glxgears framerate of about 5200 f/sec
while:
Option "NvAGP" "2" (forces X to use AGPGART)
gives me:
$ cat /proc/driver/nvidia/agp/status
Status: Enabled
Driver: AGPGART
AGP Rate: 8x
Fast Writes: Disabled
SBA: Enabled
and framerate of roughly5600 f/sec. lsmod shows that modules nvidia,
nvidia_agp and agpgart are loaded.
I'm using the same XF86Config as with 2.4.20 that used nvidia's AGP.
Any ideas?
