I just read a mail of Rob Jenkins that makes a mension of the command
'findvis'. I tried to locate singled buffered visuals on my machine
and it turned out that they have Z-buffer size of 23 or 15. And
reading the man page of glXChooseVisual showed that I was making an
impossible request. So changing to Z size 23 bits was the solution.
