I wonder how I can start mintty in Xorg-mode? (dunno if it called so) Anyway I'm using cygwin, and I execute XWin so I can run emacs in Xorg. However the default shell for XWin is xterm which I wish to change so I can use mintty instead. How to do that?
Mintty uses the Windows GUI, not X, so you can't run mintty as an X client. You can run mintty windows on the same screen as X applications, though, so you shouldn't have any problem using it instead of xterm on a system running Cygwin.
