It means that winecfg gives a warning about missing acceleration on the
commandline, but will still start (as it actually doesn't require 3d).
Which
makes sense since wine can run 2d apps without acceleration.

Umm, yes. I did state otherwise before. That is why I explained what
made me
think it was one head acceleration only - I hadn't tried any games on
windowed
mode.

No wine running whatsoever.

I'd think that there is no problem in the NVidia drivers either, since
native games
work and have always (as long as I've tried) worked with Xinerama. Also
older
versions of wine had the same problem, so any added functionality have
made
no difference. Maybe something is still missed in the Xinerama support.

Then again, it would be useful to know if anybody else has these
problems for
example with ATI cards in Xinerama.
