Hi,

i have a 1916w to have a resolution of 1440x900 (native resolution), i use a live cd (fedora 7), because by hand i didn't succeed to modify the xorg.conf of gentoo.

With this livecd, i have directly the good resolution.

I know is not the best solution, but if it work you can have a working xorg.conf

I never had problems getting the ACER AL2216W to run on its native resolution.
Note that my monitor is connected with a VGA-cable on an nvidia-card.

Comparing your xorg.conf with mine shows that I don't use any off the mode-lines or modes in the subsection display.
My suggestion would be to backup your current xorg.conf and then run "xorgconfig" to see if that gets you the correct resolution.
That's how I did it with this monitor and it simply worked.

ps) The file /var/log/Xorg.0.log should contain relevant error-messages.
In case the xorgconfig doesn't work, it might be helpful to look what exactly the error-message is.

I just solved the Problem, only had to add an Option in the "Device" section of the Graphic card
Code:
Section "Device"
   Identifier  "ATI Radeon 7500LE"
   Driver      "radeon"
   Option      "DDCMode"     "True"
EndSection

Thnx for your answers!
