The system runs okay with the VGA output. The only problem is that this
does not look good, I have shadows and the picture is not as sharp as it
is with DVI.

I do not load DRI, the only suspicious thing I could find in the logs is:

I do not know why this message is there, the xorg.conf does not say
anything about DRM.

If the system runs stable with 24 bit and VGA-output does 16 bit help
with the stability with DVI-output?

The advantage of using this would be that I get the DDC information.
Does it help with the stability as well?

Thanks and greetings
