Hello Alex and All:
Yes! This worked. The OP is very happy: http://forums.fedoraforum.org/forum/showpost.php?p=1012155&postcount=42
I'm not sure which option(s) were the critical one(s), but I know that I told him to put the "Virtual" option in the wrong place the first try. :( This time, where you showed, it must have helped. He used:
________________________________
Section "Device"
Identifier "Videocard0"
Driver "radeon"
Option "DepthBits" "16" <<==
EndSection
Section "Screen"
Identifier "Screen0"
Device "Videocard0"
DefaultDepth 24 <<==
SubSection "Display"
Virtual 1024 768 <<==
Viewport 0 0
Depth 24
Modes "1024x768" "800x600" "640x480" <<==
EndSubSection
EndSection
________________________________
Afterwards, we tried some performance tweaks, and found that the following helped greatly:
________________________________
Identifier "Videocard0"
Driver "radeon"
Option "DepthBits" "16"
Option "DisplayPriority" "HIGH" <<==
Option "EnablePageFlip" "on" <<==
Option "SubPixelOrder" "NONE" <<==
EndSection
________________________________
Thank You very much for your quick and kind assistance on this, Alex.
Thanx Again and Best Regards,
Vince

You don't have enough vram for DRI at depth 24. try depth16:
Section "Screen"
Identifier "Screen0"
Device "Videocard0"
DefaultDepth 16
SubSection "Display"
Viewport 0 0
Depth 16
EndSubSection
EndSection
if you want to keep depth 24, you'll have to either reduce the size of
your front buffer or depth buffer.
you can use a 16 bit depth buffer by setting:
Option "DepthBits" "16"
to reduce the size of your front buffer, adjust the virtual size down:
Section "Screen"
Identifier "Screen0"
Device "Videocard0"
DefaultDepth 24
SubSection "Display"
Virtual 1024 768
Viewport 0 0
Depth 24
Modes "1024x768" "800x600" "640x480"
EndSubSection
EndSection
