Dual monitors in Drake?

[Whir]

Okay, I went out and found this guy who said he knew how to set up dual monitors correctly and I did what he asked of me.

I've got all the entries for two devices, two monitors, and two screens. I've added Option "Xinerama" "on" to the ServerFlags section of XF86Config-4. I still only have mirrored monitors.

Someone out there has to be running dualies. Any ideas here?

That's exactly, EXACTLY, what I have. Well, the names are different, but that's exactly what I have.

Screen 1 "Screen1" Rightof "Screen0"

Everthing looks great. You might want to take out the option that enables Xinerma from the ServerFlags setion. AFAIK it's not required.

When I get home this afternoon I'll try to help you a bit more with this.....

[KraM]

You sure that your card and the driver you're using are capable of this?

If so, I'd try commenting stuff in the Module section, specifically dri and glx, until it works. And, I don't think you need v4l in there, in fact it breaks stuff for me...

[Whir]

It's a Radeon 9500 Pro dual head. I'm sure that part works.

Funny thing is that I install RH8 since it's still uses Xfree 4.2.0 and then used ATi's own configurator and it STILL didn't work right.

I'll try commenting out stuff methodically and see what happens.

Well, I tried to use the radeon drivers to force the second monitor to do something other than what it does, and that doesn't even work.

There's an Option "CloneDisplay" "0" which is supposed to force the second monitor to not even be on, and it doesn't work at all. I'm wondering if their radeon drivers are a bit hokie still or something.
