samsung 2343bwx xorg config

I recently acquired a Samsung 2343BWX monitor, which has an odd (but nice) resolution of 2048x1152. The thing I like most about this over my old 1920x1280 monitor is that I can have two browsers side-by-side, each at 1024 pixels wide. Before I had my two browser windows at 960 pixels wide each, and a lot of sites would wind up with a horizontal scroll bar, because they were designed for 1024x768.

Anyway, I bought it on kind of a gamble, because I couldn't find much information about whether it'd work with Ubuntu (9.04) and my onboard Intel video correctly. Turns out it does, but I had to manually add some stuff to xorg.conf.

Here is my full xorg.conf now:

Section "Device"
    Identifier  "Configured Video Device"
EndSection

Section "Monitor"
    Identifier  "Configured Monitor"
        # 2048x1152 @ 60.00 Hz Reduced Blank (CVT)
        #   field rate 59.91 Hz; hsync: 70.99 kHz; pclk: 156.75 MHz
        Modeline "2048x1152_60.00_rb"  156.75  2048 2096 2128 2208  1152 1155 1160 1185  +HSync -Vsync
EndSection

Section "Screen"
    Identifier  "Default Screen"
    Monitor     "Configured Monitor"
    Device      "Configured Video Device"
        SubSection "Display"
            Modes "2048x1152"
            Virtual 2048 1152
        EndSubSection
EndSection

I'm sure at least one of those settings is redundant, but I didn't want to go through the tedious process of narrowing it down.

I had also feared that I might need to use a real video card, but my onboard Intel video seems to be doing fine. This is what lspci lists my GPU as:

00:02.0 VGA compatible controller: Intel Corporation 82945G/GZ Integrated Graphics Controller (rev 02)
00:02.1 Display controller: Intel Corporation 82945G/GZ Integrated Graphics Controller (rev 02)

It's on an ASRock Conroe1333-DVI/H motherboard.

Hope this helps someone out there!

Oh yeah, and if you're reading this from the future, there's a decent chance you don't need to bother doing this stuff. This page was written in June 2009.
