Get and install xwinclip seperately

Change shortcut/menu bar to start cygwin in an rxvt as follows. (was run D:\Cygwin\cygwin.bat which ran bash --login -i rxvt gives proper scrolling, cut&paste, better terminal functionality than msdos terminal.

D:\Cygwin\usr\bin\rxvt.exe -fg yellow -bg darkgreen -sl 2000 -e D:\Cygwin\bin\bash.exe -rcfile d:/Cygwin/.bashrc

echo ~/.bashrc
PATH=/usr/bin:/usr/X11R6/bin:$PATH

# Start the X Server.
XWin &

#wait for X to initialise
wait_until_x_server_is_ready()
{
  while [ `grep winScreenInit /tmp/XWin.log | wc -l` -lt 1 ]
  do
    echo waiting for x server to init ...
    sleep 1
  done
  echo X server connected
}

# Start a cygwin xterm

Testing (with twm) (linux=armagh, solaris=audi)

• linux xterm/xemacs/ddd ok
• linux agere spa tool using jre ok
• linux netscape ok
• linux xfontsel/xfig/xmorph/xscreensaver ok
• linux gimp (causes seg fault with Exceed, appears okay with cygwin/XFree86
• close XFree86 without exiting xemacs/xterm etc ... shuts down cleanly on linux ok BSOD or segFault may be different story
• solaris xterm ok
• solaris xemacs moans about translation table syntax error: Unknown keysym name: xxxxxxx but ok
• solaris vxworks launch/vxsim/debugger ok (but x warnings and usual problems with pontiac/audi - can't start tcsh shell - can't tcl/tk - can't run vxsim) ok on bentley
• solaris agere spa tool using jre not ok, java.lang.NullPointerException problem seen before, perhaps it is also machine dependant (tested on audi/zeus/bentley)
• solaris ddd on bentley ok
• solaris netscape ok (on zeus)
• solaris gimp/display (ImageMagick) ok

xmodmap get from linux e.g. /usr/share/xmodmap/xmodmap.gb /usr/share/xmodmap/xmodmap.uk Works ... but I have found xterms started from xterm in X revert to not understanding keyboard again? Also keys - particularily emacs Ctrl-W is hijacked somewhere probably in .fvwm2rc

Other window managers might be useful. See .fvwm2rc-npapi in /home/jamesco/bin fvwm icewm-cygwin To start x can also put shortcut to /usr/bin/startxwin.bat on desktop, or call it from .bashrc but all changes in one .bashrc is easier to manage for multiple pcs. Can also do XWin -query saab to start full xdm session (don't need to worry about xhost + issues)
