Bug Description
Binary package hint: displayconfig-gtk
I have an Acer AL2216WSD 22" LCD panel with 1680x1050@60Hz default resolution, DVI connected.
First of all, when i use "autodetect" Xorg.conf settings (described below) everything detected 100% correctly.
-the default 1680x1050 used (already at GDM)
-only <=1680x1050 resolutions are availible
relevant Xorg.conf sections:
>Section "Monitor"
> Identifier "Generic Monitor"
>EndSection
>
>Section "Screen"
> Identifier "Default Screen"
> Device "nVidia Corporation G70 [GeForce 7600 GS]"
> Monitor "Generic Monitor"
> Defaultdepth 24
> SubSection "Display"
> Depth 24
> EndSubSection
>EndSection
To test the displayconfig-gtk i tried the following:
#1 using Plug 'n Play + 1680x1050@60Hz:
It configured my Xorg totally incorrect, resulted in a 640x480 GDM greeter sreen.
The relevant Xorg.conf sections:
>Section "Monitor"
> Identifier "Generic Monitor"
> Vendorname "Plug 'n' Play"
> Modelname "Plug 'n' Play"
> modeline "640x480@60" 25.2 640 656 752 800 480 490 492 525 -vsync -hsync

After, I correted my Xorg.conf to autodetect my settings again, then gave a second try:
Now I've selected "LCD Panel 1680x1050", but I couldn't selected this resolution because it WASNT AVAILIBLE! (lol). The availible resolutions were: 1920x1440, 1856x1392, 17920x1344, 1600x1200 (selected by default), 1280x1024, ...
I leave the default selected 1600x1200, then relaunched the program, and now the correct resolutions were availible, i could select the 1680x1050 (and finally it was the biggest).
After an X restart, GDM was launched with 1400x1050 res, but in GNOME i could select my native res. The "bigger then my native" resolutions (1920x1440, ...) were still availible.
The Xorg.conf looked like here:
>Section "Monitor"
> Identifier "Generic Monitor"
> Vendorname "Generic LCD Display"
> Modelname "LCD Panel 1680x1050"

Corrected my Xorg.conf back to autodetect again, since without displayconfig-gtk, it worked better.
Then i noticed the "Add Model" button, so i pointed to my windows Acer dirver's INF file (AL2216W.INF), imported it, i was asked if i wanted to add the following model: Acer AL2216W, clicked to Add, but then it didn't appear in Acer list.
I hope this bugreport helped, I gladly help you with further bugreports.
I used nvidia-glx-new drivers (100.14.
displayconfig-gtk (0.2+20070731ub
Made the test at 2007.09.05.
Could you please append your inf file.
