Did you install the X-startup-scripts package? Do you have /usr/X11R6/bin
in your PATH?

You did try "export DISPLAY=:0.0; ddd main_assert.exe", right? Or even
"DISPLAY=:0.0 ddd main_assert.exe"?

Actually, the other way around (first the "off-topic" part, then "set the
DISPLAY"), and you weren't chastised, just informed. The message got
redirected to this list, too. :-)
It also said "set the DISPLAY" (note the capitals). What it meant was
"set the DISPLAY environment variable to the correct value". Above are a
couple of ways that could be done.

"XWin&" should do it, but "startx" will also include some standard
command-line options and start an xterm.
