Ive had this problem for a while, When I move windows around they stretch and skip like im low on memory but im not.

This is from my xfree86 file. Can i remove the #VideoRam 4096 and change it to
VideoRam 32mb since thats what my video card has? and will that fix the jerky motion when I move windows around or something else involved?
If it matters I dont have a swap partition. Thanks

What do 'glxinfo | grep direct' and 'glxinfo | grep string' output? What FPS do you get for 'glxgears'?

I am also using an agp slot if that helps, I just think I should be getting much better performance out of this card.


$ glxinfo | grep direct
direct rendering: No
OpenGL renderer string: Mesa GLX Indirect

$ glxinfo | grep string
server glx vendor string: SGI
server glx version string: 1.2
client glx vendor string: SGI
client glx version string: 1.2
OpenGL vendor string: Mesa project: www.mesa3d.org
OpenGL renderer string: Mesa GLX Indirect
OpenGL version string: 1.2 (1.4 Mesa 5.0.2)

$ glxgears
793 frames in 5.0 seconds = 158.600 FPS
784 frames in 5.0 seconds = 156.800 FPS

Thanks

Yep, you SHOULD be getting much better performance from that card

Your drivers aren't set up properly, in fact, they aren't even being USED. X is using the Mesa drivers, which are generic drivers :/

Make sure you followed the steps properly on NVIDIA's site, you might have forgotten something.

Actually I just installed the nvidia drivers since that last post but now I get this:

$ glxinfo | grep direct
Xlib: extension "GLX" missing on display ":0.0".
Xlib: extension "GLX" missing on display ":0.0".
Xlib: extension "GLX" missing on display ":0.0".
Error: couldn't find RGB GLX visual
Xlib: extension "GLX" missing on display ":0.0".
Xlib: extension "GLX" missing on display ":0.0".
$ glxinfo | grep string
Xlib: extension "GLX" missing on display ":0.0".
Xlib: extension "GLX" missing on display ":0.0".
Xlib: extension "GLX" missing on display ":0.0".
Error: couldn't find RGB GLX visual
Xlib: extension "GLX" missing on display ":0.0".
Xlib: extension "GLX" missing on display ":0.0".

and glxgears wont start at all
Xlib: extension "GLX" missing on display ":0.0".
Error: couldn't get an RGB, Double-buffered visual

Now it's not initializing GLX at all....

Check the top of your XF86Config and make sure there is a line:

Load "glx"

And it's not commented out.

It dosnt seem to be commnented out.
What else should I check for?
Thanks

# This loads the font modules
Load "type1"
Load "freetype"
Load "speedo"

# This loads the GLX module
Load "glx"

Try installing the drivers again, maybe you'll get lucky :/

I can't think of any reason that it wouldn't initialize GLX like that.

Try checking /var/log/XFree86.0.log and try running 'dmesg' to see if it gives you any clues.

I downloaded a Nvidia driver set from nvidia but It was not from their main driver page.
I found a link to it while doing a search here on LQ. When I went to the Nvidia main Display driver download page it did not have the driver I installed. I think that might be the problem. It had ia32 and ia64 for linux. I wasnt sure If wich one to DL.The other page just had one driver but i cannot find that page yet.

How can I go about reinstalling the Mesa drivers and dump the Nvidia drivers? Kde seemed to run better with the mesa drivers. Thanks.

Change that:
Driver "nv"
to:
Driver "nvidia"
Then restart your X server and see if the problem is solved.

I just tried that and nothing.
I did find out that I am missing a whole lib directory needed by the nvidia driver (/usr/lib/tls)
When I did the Nvidia install it searched for libraries online but said none found. I wonder if I can manually install this. I dont know if this will fix the glx no loading problem but I am gonna keep on this cuz this is driveing me crazy, lol.

By the way, can you do a cat /proc/mtrr for us and tell us what comes up?

This is getting kinda deep, lol.
I dont know what any of this means but you guys must.

cat /proc/mtrr
reg00: base=0x00000000 ( 0MB), size= 512MB: write-back, count=1
reg01: base=0xd0000000 (3328MB), size= 64MB: write-combining, count=1

Heres this also:

modprobe nvidia

Module nvidia loaded, with warnings

Well I didnt want to but I uninstalled the nvidia drivers using the unistaller provided but nothing changed, my xfree86 file is exactly the same as it was and my graphics are no better. I have a feeling my XFree86 file is doing nothing cuz Ive made several changes and nothing different has happend. Is there another config file that controls Graphics and the mouse?? Thanks

I got the nvidia driver to work!!
I was modifying the wrong file, I was changing the XFree86Conf file and I was supposed to edit the xorg.conf file.
but the graphics are still really jerky when I move windows around, but glxgears is showing almost 6 times the FPS than before.
