- Hello,
-
- I'm running X-Windows on my Linux PC (0.98 pl4/5) with an ATI
- graphics vantage card and the new Xlinux.8514 driver. Everything
- works fine ...
- BUT: xdpyinfo reports that only 6 bits are significant in color
- specification. That's sad, because I want to implement and test
- some image processing tools and 256 different colors are absolutely
- necessary for doing this job.
-
- QUESTION: Did I make some configuration mistakes ?? Is the 6 bit significance
- a feature (what a pity) --> the hardware of the graphic card can
- display 256 different colors !!!!
