Messy OpenGL

djib · 04-24-2005, 07:24 AM

Hello,
On my computer, OpenGK is really messy. All textures keep on 'flashing'. This means I cannot use openGL.

glxgears says
2450 frames in 5.0 seconds = 490.000 FPS
2642 frames in 5.0 seconds = 528.400 FPS
2249 frames in 5.0 seconds = 449.800 FPS
2270 frames in 5.0 seconds = 454.000 FPS
which is not too bad I think, but the gears are sometimes turning really fast, and sometimes it seems like they are not moving anymore.

If you have any idea...

Need more info. Graphics card? NVidia or ATI?

I have a ATI Radeon 7500....

So you're using DRI. Maybe there're some issues with DRI or agpgart.
Could you please post your Xfree/Xorg config?

Hello
You want me to post the content of my /etc/X11/XF86Config-4 file ?
Here it is...

Code:

# XF86Config-4 (XFree86 X Window System server configuration file)
#
# This file was generated by dexconf, the Debian X Configuration tool, using
# values from the debconf database.
#
# Edit this file with caution, and see the XF86Config-4 manual page.
# (Type "man XF86Config-4" at the shell prompt.)
#
# This file is automatically updated on xserver-xfree86 package upgrades *only*
# if it has not been modified since the last upgrade of the xserver-xfree86
# package.
#
# If you have edited this file but would like it to be automatically updated
# again, run the following commands as root:
#
#   cp /etc/X11/XF86Config-4 /etc/X11/XF86Config-4.custom
#   md5sum /etc/X11/XF86Config-4 >/var/lib/xfree86/XF86Config-4.md5sum
#   dpkg-reconfigure xserver-xfree86

I don't know if this helps, but
try replacing

Section "Device"
Identifier "ATI Technologies Inc Radeon Mobility M7 LW"
Driver "ati"
EndSection

with

Section "Device"
Identifier "ATI Technologies Inc Radeon Mobility M7 LW"
Driver "radeon"
EndSection

or Driver "r100" (however I think r100 doesn't exist)
