Just to be clear---in case anyone might be confused by my sloppy wording---I rotated clockwise each of the two 1600x1200 LCD panels attached to my docking station. Then I used 'Option "Rotate" "Left"' on each of them. With side-by-side monitors, each in portrait orientation (instead of the usual landscape orientation), my virtual desktop size was then 2400x1600.

Thanks! I'll fetch the relevant debs from experimental with a Web browser. I'm an old guy who still uses dselect for package stuff, and I can never remember how to use apt (to "pin" or whatever) the right bits from experimental. I suppose that there's an Option to use in xorg.conf to enable EXA instead of XAA. > On second thought, I'm afraid this won't help as the 3D engine > probably only supports textures up to 2048x2048. Well, that would matter (hopefully) only if I actually wanted to use textures bigger than 2048x2048. Perhaps it would affect me if I wanted to use a big texture for the whole virtual desktop. Doesn't compiz do something like that? Although running compiz would be nice, I just want my screen saver and ordinary OpenGL apps to work without putting garbage onto the screen. Anyway, would it be a huge pain for me to check out the source and build it myself? I use cvs and subversion a lot at work, but I've never messed with git. Also, I do embedded programming in C at work. Is there a huge learning curve in coming up to speed on the source and build system for what Debian calls xserver-xorg-video-ati? I'm not opposed to playing around with it, but my time is limited enough so that I probably can't afford to climb a huge learning curve. -- Thomas E.
