Harold,
Although I haven't been able to get the Frame Buffer test 10 to work,
I can get test 6b to start but it has all the wrong colors. In
trying to troubleshoot the problem, I ran across the xdpyinfo utility.
Below is the output for 1) test6b, 2) Xwin-x11 3) eXceed V6.2.
For both 2 & 3, the colors look normal. I wonder if the red, green, and
blue masks means and why are they different for different xservers?
How do they get set?
TIA,
--Kevin
