GL/CLX Parts missing
Linux scorpy 220.127.116.11-60.fc8 #1 SMP Mon Jul 21 02:06:29 EDT 2008 i686 athlon i386 GNU/Linux
02:00.0 VGA compatible controller: nVidia Corporation NV18 [GeForce4 MX - nForce GPU] (rev a3) (prog-if 00 [VGA controller])
(440MX on motherboard (shared memory)
NVIDIA Driver Version: 96.43.07
I am running dualhead (TwinView). 2 x 17" lcd's at their native resolutions (1024x768). I am running at 16 bpp, because this system has never been able to run dual head at 32 bpp. due to the speed of the shared memory.
3-D parts of many programs are simply missing.
The earth is missing in GoogleEarth (see attachment)! Extreme Tux Racer starts with just the pale blue background. By guessing key presses, I can start a game, and tux is rendered, and runs at good speed, but the scenery is missing(see attachment).
Must OpenGL xscreensaver modules run fine, but some do have parts missing, or simply result in a blank screen. CPU load is normal, and all 2D stuff seems fine. System is stable, moving windows, etc. seems to have good speed.
There is nothing helpful in Xorg.0.log, and no errors.
System was previously running a much older version of fedora, and a very old NVidia driver. I had not updated for years. In the old configuration, I was limited to 16bpp, but 3D stuff (specifically tux racer) worked fine.
The problem started when I upgraded to Fedora 8. At first, I was using the 96.43.05 driver with a patch. When 96.43.07 appeared, it built and installed fine (no patch needed), but the problem persisted.
xorg.conf is as the nvidia installer creates it, with the exception that I had to comment out the FontPath line
I have tried dropping down to 1 monitor, (TwinView off) but the problem persists.
I know one answer is to buy new hardware, and I may do that, but I would still like to know what is going wrong here.
Thanks in advance for any help you can provide.
