Hello all;
I'm trying to get accelerated graphics working properly on my system.
I have an AMD Athlon XP cpu, AMD 761 AGP, and an NVIDIA GeForce 2 MX video card.
A couple of months ago, I installed Debian stable, then installed XFree86 version
4.?.? from Debian Woody. I then install the nvidia accelerated graphics kernel driver
and GLX library. Everything worked great, notably a 3D game called Andromeda9 played
very well and always reported 100 frames/sec (+/- 2 or so). I played around with bios
AGP settings; there were some small improvements and everything functioned as expected.
Another game called Heretic II kept crashing the computer. I assume the cause of the
crashes is some bug in Athlon memory paging conflicting with the AGP memory access (or
whatever -- seems to be some babbling on the net about this). Eventually the ext2 file
system became corrupt and I could no longer boot the computer.
So I reinstalled Debian, this time using a Woody reiserfs install cd. Once again, I
have installed the nvidia glx library and kernel module. The accelerated graphics
function but at a much reduced rate: Andromeda9 is now 30-50 frames/second (the number
is much lower and it varies much more than it used to). Also, I think the games use
much more cpu resource than they used to (I can't quantify this because I don't
remember exactly what the cpu usage was previously). Further, the mouse behaves funny
- it doesn't move smoothly and sometime jumps around on its own. I'm sure the
accelerated graphics is enabled because if I disable it things REALLY slow down.
I don't know what I did differently on my second install. I have tried a number of
things to fix the problem: both nvidia and linux agpgart for agp access. I have
upgraded to XFree86 4.2.0. I have removed ethernet drivers from the kernel (thought
maybe one of them conflicted). I tried not loading any XFree86 extensions. I removed
all traces of libGL* from my system, and replaced with the NVIDIA ones. All to no
avail.
So, my questions are:
- any idea what else I could try?
- I've notice the nvidia XFree86 extensions report that they are compiled for X
version 4.0.2, whereas I have version 4.1.something, then 4.2.0. Could this be a
problem?
- The man page for the XFree86 nv driver says that it is fully accelerated. When I
try the driver, I don't think any acceleration is going on. For sure the 3D games
don't get accelerated. I have the agpgart module loaded when I start up X. Do I have
to do anything else? Does the nv driver really use full acceleration?
- Is there another place to post this message?
Thanks for your help. I attached some pci info below, just in case it's of any use.
Let me know if I should post more information.
