External monitor/projector on Acer Aspire One without restarting X

Hi, I have an Acer Aspire One, running Slackware 12.2. The graphics device in this machine is identified as follows:

00:02.0 VGA compatible controller: Intel Corporation Mobile 945GME Express Integrated Graphics Controller (rev 03)
00:02.1 Display controller: Intel Corporation Mobile 945GM/GMS/GME, 943/940GML Express Integrated Graphics Controller (rev 03)

What I would like to do is use this machine for talks and stuff, so would like to connect it to a projector (or external monitor, because sometimes I use those as well), but without having to restart X. Also, I want the output from the machine to be on both the netbook's screen and on the external monitor/projector simultaneously. I also have the problem that when I've got an external monitor or projector connected, the display doesn't fit on the netbook's screen (i.e. the bottom part of it is cut off). The full display is shown on the monitor or projector, though.

What's the best way to do all this?

Hi, I've used the command xrandr for my toshiba L30-100 laptop and was able, by scripting the various options offered to send video over to the projector. Please check the xrandr man.

Try pressing Ctrl-Alt-F1 to switch to a Virtual Terminal, press the appropriate FN keys to make the Virtual Terminal appear however you want it, and then press Ctrl-Alt-F7 (or the number 1 above however many virtual terminals you have) to switch back to a GUI. I don't have an Acer, but that works for me with a Dell with a similar Graphics controller. Hope that helps.
