OK. I've installed 8.10 on my emac (1.25ghz "USB 2.0" emac).

I did the modprobe idescsi thing, got the sound working, set up the dual boot with OSX, etc.

But I can NOT get the @#%$(*#(%@# xorg.conf set correctly to save my life.

I've tried like 3 or 4 different xorg.conf's posted by various people who claim to have emacs. I've set the refresh rate, used read-edid to get the modelines, etc.

And yet, I have exactly two options.

Xorg.conf with ANYTHING in it (at least, anything I've tried): Blank scren.

No xorg.conf (delete the file): Low graphics mode.

If I could even figure out what to put in xorg.conf to get the exact same behavior as low graphics mode I would be thrilled, because at least I'd have a starting point!

Can we start there? Does anyone know what a "low graphics mode" xorg.conf would look like?

Oh and one more thing: Can someone please tell me a simple way to restart X without having to reboot? I.E. I edit xorg.conf, get a blank screen, I can switch to a terminal, make another xorg.conf edit, then.... sudo kill something? startx?

Isn't it amazing how you can't figure something out until you ask?

I was missing the 'Driver "fbdev"' line.

For those other emac users out there, the following is my (now working) xorg.conf:

(and yes, it's an eMac, the monitor is called "iMac" because that's how read-edid identifies it).
