I am trying to setup my laptop for a presentation, i.e., to have the same content on the internal and external screens.
ATI's clone mode seems to be what I am looking for, and it actually works. Unfortunately, the external screen's resolution is always the same as the laptop's, which looks bad (the laptop is wide screen). Clone mode (as opposed to Mirror mode) is supposed to enable different resolutions and refresh rates, but I can't get it to work. Nor did I find any reasonable documentation on how to do that.
Any thoughts?

Well I'm actually interested in neat way to do this myself.
I was recommended fglrx-control which let's you modify settings for tv-out and other card specific features.
There's a few tools which comes with ati (man ati I think, or aticonf or similar) which let's you manually set changes.
Take a backup of your xorg.conf before issuing any new commands, then enable all the featues of your choise from there.
Hope this was of any help.

Might I suggest not using clone mode? I've given presentations with my laptop, and I found that putting my slides on the external monitor with my outline on the laptop screen worked well. As long as you can sneak a glance at the main screen to make sure it's showing what you think it is, why do you need a duplicate? Of course, your presentation style may differ from mine, but I don't put anything on the screen unless I'm actively talking about it, and blank it otherwise so the audience isn't distracted.
Pardon me if you're doing something other than what I think you are.
