           Summary: ATI 9200 on LG 226WTQ does not show 1680x1050 correctly
                    on VGA
           Product: xorg
           Version: 7.2
          Platform: x86 (IA32)
               URL: http://temp.mkcs.at/linux/ubuntu_ati_vga.jpg
        OS/Version: Linux (All)
            Status: NEW
          Severity: major
          Priority: high
         Component: Driver/Radeon
        AssignedTo: xorg-driver-ati at lists.x.org
        ReportedBy: mkspamx-common at yahoo.de

I have Ubuntu 7.10 on my system. If I set the screen resolution to 1680x1050,
the screen "virtually" starts beyond the border of my real screen. That means,
parts of the picture are missing and I can't see about 10% of the left and
right screen. The height is so far okay. My monitor reports that 1680x1050 is
the current solution. If I shift the picture to the right with the monitor's
OSD menu, I see the left part but the picture is then splitted by about two
thirds. This behaviour only appears if I connect my monitor on the VGA
connector (which I must do actually). If I connect it via DVI, the problem
disappears (but isn't solved for me). I have to set my screen resolution to
1400x1050 to see the whole screen. After some hacking the xorg.conf file, my
monitor now reports me 1680x1050 but everything has more width then normal. For
example, if I watch a photo of my old 4:3 monitor, it looks like the
width:height radio would be 1:0,63 instead of 1:0,75. Please see the picture at
the URL specified above.

Because this all did not happen in my old openSUSE 10.2 installation, I guess
this is an error in the X server, whereby it's hard for me to say in which
component the error is inside. So please forgive me if I made a wrong guess.

I have uploaded my current xorg.conf file:

The xorg.conf file that the Ubuntu installation generated can be found here:

http://temp.mkcs.at/linux/xorg.conf.ubuntu

The xorg.conf file of my old openSUSE 10.2 is retrievable here:

http://temp.mkcs.at/linux/xorg.conf.suse

About my X Server version I am not absolutely sure, but
http://packages.ubuntu.com/gutsy/x11/ states 7.2.5 so I guess that's okay.
