5) Both outputs are changed together by xrandr. I've compiled a fairly recent version of the X server and xrandr (git of beginning of September) and, when I act on one output with xrandr, both change together. For instance, if I type
xrandr --output VGA_1 --right-of DVI-I_1/digital
both output go to (1024,0). I always get same resolution and same position for both outputs. The outputs are not in parallel because the EDID are different for both screens.
That's what I've found after some tries. With a single screen it works ok. With two it's a problem (and that's unfortunate because I'd like to make a two-seat computer).
I have no idea whether this is an RandR FAQ, a known RandR issue, or an issue that still has to be dug out. I hope that Matthias can shed some light on this one.
I've just discovered today that "ati" driver seems to be able to drive the chip also (I'm not in front of the screen, so I can't check it effectively works, but it looks very much like it). RandR seems to work ok with the "ati" driver, while it does not with the "radeonhd" driver (everything is equal in both setups, I just change the Driver in xorg.con). I'll be seeting in front of the screen next week, probably on monday, so I can make further visual tests by then.
