Hi James,

thank you for your help ! :)

Hmmm...that is a kind of frightning to me...
On my previous system I had a nvidia GT7200 or GT7500 (cant remember
exactly) and makehuman does work with it.

Now I have a 
    nVidia Corporation G96 [GeForce 9500 GT] (rev a1)
according to lspci. So this card /seems/ to be more advanced -- at
least to me when I took a look at the numbering 7200<->9500.

I am using the propietary nvidia drivers. No problems since now exept
for the use of makehuman.

"male_formed" ... sorry James, what does it mean...English isn't my
mothers tongue...does it mean something like "falsy compiled", "badly
built"?

Framebuffers? Hu? I thought, these wre only used when dealing with the
bare console or when using X in cases there is no support for the
graphics card. Please give me a hint here...

Ok, I will check that, thank you James...

Is there something else...for example in xorg.conf to switch on or off
to get this z-buffering working?

Have a nice weekend!
