Public bug reported:
Binary package hint: displayconfig-gtk
I have an Acer AL2216WSD 22" LCD panel with [EMAIL PROTECTED] 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 + [EMAIL PROTECTED]:
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 "[EMAIL PROTECTED]" 25.2 640 656 752 800 480 490 492 525 -vsync
> -hsync
> Gamma 1.0

>Section "Screen"
> Identifier "Default Screen"
> Device "nVidia Corporation G70 [GeForce 7600 GS]"
> Monitor "Generic Monitor"
> Defaultdepth 24
> SubSection "Display"
> Depth 24
> Virtual 640 480
> Modes "[EMAIL PROTECTED]"
> EndSubSection
>EndSection

>Section "device" #
> Identifier "device1"

> Device "device1"
> Defaultdepth 24
> Monitor "monitor1"
>EndSection
>Section "monitor" #
> Identifier "monitor1"
> Gamma 1.0
>EndSection
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"
> Horizsync 31.5-90

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 (100.14.11+2.6.22.3-1),
displayconfig-gtk (0.2+20070731ubuntu1)
Made the test at 2007.09.05.
