I upgraded from Slackware32 to Slackware64 and I also upgraded to the latest NVIDIA driver so I now have 30 support for my 30 bit monitor, but I find that UFRAW will display any picture as a black panel.  When I setup the pixel depth to 24 in 'org.conf' UFRAW shows the picture allright.
  Is there anyone on this forum using a 30 or 32 bit deep panel in Linux.  Is there some thing I would need to know to activate 30 bit visuals in UFRAW besides modifying xorg.conf.
