OverlayAndNoDITest results

[Przemyslaw Bazarnik <pb at syntekt dot com dot tw>]

Harold,

I got some results form my setup

OS: Windows NT 4 SP5
Language: US English
Cygwin 1.1.4  
(Old files work correctly - only the random input problem while switching screens)

Looks like something trivial... (?)
During all this some other window is flashing for a microsecond 
(it seems white to me :-))


BTW If I well remember, there was an intention to document (a HOWTO ?)
how to setup environment for compiling current Xserver. Do you use gcc
to compile the Windows related code some other compiler is required (VC)?

Cheers,

> Extract the test archive like so:
> cp OverlayAndNoDITest.tar.bz2 /usr/X11R6/bin
> cd /usr/X11R6/bin
> mv XWin.exe XWin.orig.exe
> mv xf_dx.dll xf_dx.orig.dll
> bunzip2 OverlayAndNoDITest.tar.bz2
> tar -xf OverlayAndNoDITest.tar
> 
> Edit your /usr/X11R6/bin/startxwin.bat file to contain the following line,

> Unfortunately, overlays must be allocated in video memory in addition to the

> Try decreasing your current display depth if you cannot get XWin to start

> Please post to the list if the test does not work for you (include your OS,

> Please post your suggestions to the list.
