Description Jasmin Buchert 2007-06-23 02:48:11 UTC 
X.org does not correctly detect the display size of my TFT display (Samsung 181T). I use "DisplaySize 359 287" to set the right dimensions.
With the randr-1.2 branch of xf86-video-ati that doesn't work. It uses the detected EDID values  (338mm x 270mm).
Using xrandr --fbmm 359x287 also doesn't work (still the EDID values), but xrandr --dpi xx works.

Can you attach you xorg log and config?

you need to associate your monitor section with an output.

"Monitor-<output name>"

in the device section:
Option          "Monitor-VGA" "Samsung SyncMaster 181T"
Comment 5 Jasmin Buchert 2007-08-25 03:18:04 UTC 
With that it uses 800x600. I have to add Option "PreferredMode" "1280x1024" to the Monitor section. But should'nt it use the native resolution (1280x1024) by default?
It now correctly assigns the Monitor section to the output, but I still have to do xrandr --fbmm 359x287 in my .xprofile. Without it the fonts are too large.

That's also kind of weird:
(WW) RADEON(0): Option "PreferredMode" is not used
I'm sure it uses the option.

Can you try again with ati from git or release 6.7.195?

Fixed in xserver git.
