Switching monitors 'on the fly'

what do i type here · 2008-06-15 00:38:18

I won't go into details but here's the basic situation:

My system is normally connected to a 15" LCD display, but occasionally I need to hook it up to a 22" widescreen display.

What is the best/easiest/most elegant way to do the switching back and forth? Do I need a separate xorg.conf for each 'mode'? is it as simple as switching resolutions with CTRL+ALT+backspace?

thanks for any information.

Note: that I am not talking about a dual head configuation here. The computer is never connected to both at once.

Interesting username, haha!

Are these always LCD monitors, or are they CRT moniotrs. If you omit the modes section in your xorg.conf, X should automatically detect the resolution.

xrandr may be woth to look into. you can change output, resolution etc without restarting X.

Edit: if you only have to switch between two resolutions, hint in the above post will probably be the best way. sorry for confusion.

These are both LCD monitors, I should have mentioned that. So you're saying that it should be pretty much automatic?

Yeah they should be, try it out and let us know!

Doesn't X autodetect settings only on when it starts?

Yeah but a ctrl+alt+backspace will kill x

Xrandr might let him change the resolution without restarting X then.

Yeah I'd prefer not to restart X

Oh and I don't have both monitors yet (one is on its way) so i can't test it out. I posted this thread so I would be prepared and to know what to do.
