Not sure why this happens, but something gets messed up in the xorg.conf
by using the automated tools. Here's a few parts of the original
xorg.conf posted on this page:
Section "Monitor"
Identifier "Configured Monitor"
EndSection
Section "Monitor"
Identifier "Monitor0"
VendorName "Unknown"
ModelName "Sony CPD-G420"
HorizSync 30.0 - 110.0
VertRefresh 48.0 - 170.0
EndSection
Does the user have two monitors? Doubtful. So there shouldn't be two
monitor entries. I would suggest removing the first "Monitor" entry.
Section "Device"
Identifier "Configured Video Device"
Driver "nvidia"
Option "NoLogo" "True"
EndSection
Section "Device"
Identifier "Device0"
Driver "nvidia"
VendorName "NVIDIA Corporation"
BoardName "GeForce4 MX 440 with AGP8X"
EndSection
Two devices? Probably not. I would strip out the first one, but you
may want to consider keeping the Option and putting it in the second
"Device". (Would prevent the computer from showing the nVidia logo when
X starts. Your choice.)
Section "Screen"
Identifier "Default Screen"
Device "Configured Video Device"
Monitor "Configured Monitor"
DefaultDepth 24
Option "AddARGBGLXVisuals" "True"
Option "DisableGLXRootClipping" "True"
EndSection
Section "Screen"
Identifier "Screen0"
Device "Device0"
Monitor "Monitor0"
DefaultDepth 24
Option "TwinView" "0"
Option "TwinViewXineramaInfoOrder" "CRT-0"
Option "metamodes" "1600x1200_75 +0+0"
SubSection "Display"
Depth 24
EndSubSection
EndSection
Here things get trickier. Notice how "Screen0" is mentioned in the
"ServerLayout" section of xorg.conf, so you need to keep those two
identifiers coordinated. You'll also need to make sure that the
"Device" and "Monitor" setting listed here match what you have for
identifiers above.
I believe that you can get away with deleting the TwinView settings, as
you appear to be using the defaults. But I would suggest taking the two
options from the first "Screen" entry, moving them into your second
"Screen" entry, and removing the first "Screen" specification.
I don't know what makes the duplicate entries, but I've found on my own
computer that simplifying xorg.conf makes it obey quite a bit better.
Finally, you indicated that you tried to update how compiz handles
rendering. See bug 294076. Looks like others are going the opposite
way and changing how nVidia handles rendering by changing xorg.conf.
Try adding:
Option "RenderAccel" "0"
to your "Device" settings, and see if that helps your rendering
problems.
