You might try looking at this thread on Google Groups. I found it by
searching for "sun blade visual".

http://groups.google.com/groups?hl=en&lr=&ie=UTF-8&a mp;oe=UTF-8&threadm=3b66f048
.0%40cfanews.harvard.edu&rnum=5&prev=/groups%3Fhl%3D en%26lr%3D%26ie%3DUTF-8%
26oe%3DUTF-8%26q%3Dsun%2Bblade%2Bvisual

The thread suggests that there is a patch available that solves a problem
with lack of 8-bit support on some Blade machines with certain mind-boggling
collections of graphics hardware. But the discussion seems to suggest that
the 8-bit PseudoColor visual does show up in xdpyinfo output if the visual
exists and does not show up in xdpyinfo if it is not there.

IDL throws that error message when it can't find the requested visual in the
result of a XGetVisualInfo call. This leads me to believe that your server
is not really listing this visual. Perhaps you can post the output from
xdpyinfo? (This will give me some other clues)
