Hi,
I've a monitor Acer AL1916W and an integrated graphics controller, and the problem is that I can use resolution 1440x900 but a box with text "Input not supported" is showed around the display. That resolution works fine in windows, and as I said, I can select that resolution in gnome but appear thats error. How can I solve that issue, I tried a lot of configs of xorg, changing Modeline, with the same result.

My lspci -v|grep VGA is:

I had to tweak my xorg.conf with the right modeline to get this monitor work at the right resolution; this is my "section monitor":

OK, I tried your ModeLine suggestion in my xorg.conf, but the problem didn't solve.
I installed the read-edid package but the command get-edid don't come with it, It only installed the command parse-edid.

I want to explain that gnome show me the option 1440x900@75 and 1440x900@60 in the "Screen Resolution" menu, I can see very good the resolution, the only problem is the box with text "Input not supported" that is floating around the screen, this is with 75Hz, when I select 1440x900 at 60Hz, the resolution is not good and the desktop is displayed off the screen.

I tried with a Ubuntu Live CD and the resolution was displayed fine, at 1440x900@75.

Thanks in advance for any help.

Hi Adebisi,

I use the same monitor but with a Nvidia 6600LE graphic card. Here is my xorg.conf file, which works pretty fine with 1440x900 resolution on my box.

OK, thanks for all your help, but I can't do that the monitor work in 1440x900(60 or 75)
With 60 the desktop go out of screen (I can't see the bottom panel), with 75 resolution is great, but with a float box telling me that the frequencies aren't supported.
With resolution of 1280x1024 all is blur.

Is strange because with windows and Ubuntu LiveCD I can use 1440x900.

Right now I'm tired to probe modelines, read the manual of monitor, etc.

Thanks for all, I think that I will change my Gentoo for Ubuntu.

Ok, one more thing.

After reading your last post, I suspect that the resolution is set to 1440x1024 (the output of "xdpyinfo" should help).

I have only resolution "1440x900" in xorg.conf since some days ago.

Now, I use xvidtune in Ubuntu Live CD and get the right values for ModeLine, and now the resolution 1440x900 at 60Hz is working, BUT, all is more biggest.

How can I solve this issue now?

This is my xorg.conf right now:

OK, I solved last problem changing DPI value in the control-center of gnome.

I tried to set DPI in xorg.conf using 'Option "DPI" "96x96"' but xorg didn't take that value and log file showed me "(WW) intel(0): Option "DPI" is not used".

Finally, I solved the issue changing ModeLine in xorg.conf, I got the right values for ModeLine using xdpyinfo on Ubuntu Linux LiveCD.

Thanks to all for your help!.

Bye.
