Hi everyone,
I am having problem with getting colors correct for certain X applications
that originally ran on Digital Unix workstations. The details are below. Any
help would be appreciated.
The command I ran in cygwin was:
XWin.exe -fullscreen -depth 8 -emulate3buttons 100 -unixkill -query dmsdev
where dmsdev is a digital Unix machine.
As Harold suggested, I used xdpyinfo with XWin and the digital unix
workstation.
The following is firstly the result for XWin...

Here's the output of xdpyinfo on the Digital Unix workstation.
