Dear Cygwin/Xwin maintainers:
First let me say that I am running Cygwin/XFree 6.8.1.0-9 on a Windows XP
box. I start X with the default parameters (plus -clipboard).
Here's what I want to do, and what happens:
-- Want to: Use the XP Display Properties > Settings menu to add. on the
fly, a second display, namely a video projector. I "Extend the Windows
Desktop" to this projector for displaying PowerPoint slides. I want X to
stay the way it was, in an XP window that covers the whole laptop LCD
screen, but not displaying on the video projector.
-- What happens: When I do this, after the display configuration change,
the X window contents no longer display, though the cursors show and
input appears to be active. XP things work as expected, and I can move
the cursor from one screen to another, etc. PowerPoint does the right
thin, showing presenter view on LCD screen anbd slide show on video
projector. Once I am done and change the configuration back to one
display, X works again like normal.
Any suggestions? Or is this going to need some heavy duty programming to
fix?
Regards -- Eliot Moss
