Using XRandR 1.2 with the latest git version (last log entry is from Sun Oct 28th 21:10) of the radeon driver I can't get a virtual desktop of 3080x1050. I have a Laptop with a widescreen display running on 1680x1050 and a CRT which can run 1600x1200 at max. With Xorg 7.2 and Xinerama I've used a 1400x1050 resolution on the CRT, but this doesn't work anymore with XRandR. When using the attached xorg.conf I get the xrandr output that the minimum size is 320x200, current size is 3360x1050 and the maximum is 3080x1050. And the display is broken too, as part of my xterm is cloned on the outer right of the right display. I can force the CRT to run at 1680x1050 with an according modeline, however that distorts all fonts and stretches them vertically. I'll also attach the Xorg.log

I had the similar problem. I had got wxsga+ monitor (22'). And I tried to use 1680x1050 mode. But I always got 1400x1050 resolution. Until I set UseFBDev. After that resolution is fine.

Does it work ok if you turn off the CRT and them use xrandr to set up dualhead? xrandr --output VGA-0 --off xrandr --output VGA-0 --mode 1400x1050_85.00 xrandr --output VGA-0 --left-of LVDS

Is this still an issue with a newer driver (6.9.0 or newer)?
