activate new xorg configuration without restart xorg

[Li Guanglei]

I am using ATI Proprietary Linux driver and configured twin-view
(expand desktop mode) for my laptop. But every time I want to switch
to the twin-view mode, I have to logout or Ctrl+Alt+Backspace to
restart xorg to make xorg find the second display and activates it.
Anyone knows how I should do to switch between single-view and
twin-view mode without restart xserver?

Thanks.

I assume you have two xorg.conf files what you switch when you want DualView
or only output on LCD, you don't get Xorg to reread the configuration file
while running. If you want to change settings you use tools like xmodmap, xrdb
and xset, but you will have a limited options (you can't do all the things you
can in the config file).

If you don't want to have DualView all the time, then I would suggest you try
to run the LCD as one X session and the TV-out as another X session, when you
want TV-out you start another instance of X.
