Graphics Problem


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

Re: Graphics Problem

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.

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.

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
Warning: loading /lib/modules/2.4.22/kernel/drivers/video/nvidia.o will taint the kernel: non-GPL license - NVIDIA
See http://www.tux.org/lkml/#export-tainted for information about tainted modules
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.
