For x server (Cygwin X server hosted on windows platform) the alt-tab program switcher does not work. The x server window (in my case gvim) does not show up in the list of windows when using alt-tab. Although the window is present in the taskbar at the bottom of the screen. Any help is highly appreciated.
If you start XWin with the
-keyhook option, alt-tab will work. See the XWin(1) manpage. You can do this by creating the file
/etc/X11/xinit/xserverrc with the following contents:
exec X :0 -keyhook
