Hi, at last i got it work but i'm not pleased because i couldn't see
any performance increment. To solve the problem i simple added this
line in device section:
Option "NvAGP" "1"
which tells X to use NVIDIA internal AGP. (Note that i tried all values
for NvAGP. 2 and 3 didn't function, black screen again, 0 and 1
functioned). With that i could see the Nvidia splash image at gdm
startup. Also i tested my card again with "glxinfo | grep direct" and
"glxgears", worked with no errors:
glxinfo | grep direct
direct rendering: Yes
As i told i'm not pleased, here is my glxgears outputs:
1- Just after a gnome session, no additional program is running:
860 frames in 5.0 seconds = 172.000 FPS
973 frames in 5.0 seconds = 194.600 FPS
1003 frames in 5.0 seconds = 200.600 FPS
1004 frames in 5.0 seconds = 200.800 FPS
1004 frames in 5.0 seconds = 200.800 FPS
1003 frames in 5.0 seconds = 200.600 FPS
1004 frames in 5.0 seconds = 200.800 FPS
1004 frames in 5.0 seconds = 200.800 FPS
1004 frames in 5.0 seconds = 200.800 FPS
1004 frames in 5.0 seconds = 200.800 FPS
1003 frames in 5.0 seconds = 200.600 FPS
2- When i only move the terminal window continously (drawing circles) :(
83 frames in 5.0 seconds = 16.600 FPS
35 frames in 5.0 seconds = 7.000 FPS
43 frames in 5.0 seconds = 8.600 FPS
40 frames in 5.0 seconds = 8.000 FPS
41 frames in 5.0 seconds = 8.200 FPS
34 frames in 5.0 seconds = 6.800 FPS
43 frames in 5.0 seconds = 8.600 FPS
36 frames in 5.0 seconds = 7.200 FPS
28 frames in 5.0 seconds = 5.600 FPS
38 frames in 5.0 seconds = 7.600 FPS
37 frames in 5.0 seconds = 7.400 FPS
I've searched for performance tricks and found options like
RenderAccel, also tried it with "true" value but it only decreased
performance. Can this be a kernel issue?. Or maybe NvAGP wansn't the
real solution..
