Error enabling 1600x900@60Hz resolution in xorg.conf


I just got a new system with a Dell ST2010F widescreen display. After going through Debian's standard install, I've wound up with a resolution of 1024x768. After some Xorg research, I came up with the following xorg.conf:

Code:
Section "InputDevice"
        Identifier      "Generic Keyboard"
        Driver          "kbd"
        Option          "XkbRules"      "xorg"
        Option          "XkbModel"      "pc104"
        Option          "XkbLayout"     "us"
        Option          "XkbOptions"    "ctrl:swapcaps"
EndSection

Section "InputDevice"
        Identifier      "Configured Mouse"
        Driver          "mouse"
EndSection

Section "Device"
        Identifier      "Configured Video Device"
        Option          "UseFBDev"              "true"
EndSection

Section "Monitor"
        Identifier      "Configured Monitor"
        Modeline        "1600x900" 97.75 1600 1648 1680 1760 900 903 908 926 +hsync -vsync
EndSection

Section "Screen"
        Identifier      "Default Screen"
        Monitor         "Configured Monitor"
        Device          "Configured Video Device"
        DefaultDepth 24
        Subsection "Display"
                Depth       24
                Modes "1600x900" "1024x768" "800x600" "640x480"
        EndSubsection
EndSection
However, when I restart X with this configuration, I get the following messages in my /var/log/Xorg.0.log:

Code:
<snip>
(II) VESA(0): Total Memory: 256 64KB banks (16384kB)
(II) VESA(0): Configured Monitor: Using hsync range of 30.00-83.00 kHz

(II) VESA(0): Not using built-in mode "1600x1200" (width too large for virtual size)
<snip>
There very clearly is a mode in the xorg.conf named "1600x900", so I don't know where that message is coming from... Any idea what I'm doing wrong?

I don't think the Vesa driver can run to that high a resolution.
Is there a particular reason you are using the Vesa driver?.
The output of lspci | grep VGA would be helpful.

Ah ok. My video card is an ATI Radeon HD 4350 (512 mb). I was trying to fix the resolution before I tried tackling the special-video-driver issue, but I guess I need to do both at once.

Here's the lspci output:

Code:
01:00.0 VGA compatible controller: ATI Technologies Inc Device 954f (prog-if 00 [VGA controller])
Using the xorg.conf above, I added:

Code:
Driver "radeonhd"
in the "Device" section. Restarting gdm fails with the following in the Xorg log:

Code:
<snip>
(II) LoadModule: "kbd"
(II) Loading /usr/lib/xorg/modules/input//kbd_drv.so
(II) Module kbd: vendor="X.Org Foundation"
        compiled for 1.4.0.90, module version = 1.3.1
        Module class: X.Org XInput Driver
        ABI class: X.Org XInput driver, version 2.0
(II) RADEONHD: X driver for the following AMD GPG (ATI) graphics devices:

(II) RADEONHD: version 1.2.1, built from non-git sources

(II) Primary Device is: PCI 01:00:0
(--) Assigning device section with no busID to primary device
(EE) No devices detected.

Fatal server error:
no screens found
Googling that error gets me nowhere. Is my card not supported by that driver yet?

The Vesa driver is a last resort,typically it will work with most video devices but give fairly poor performance.
The following guide is helpful for installing the Ati drivers with Debian:

http://wiki.cchtml.com/index.php/Deb...allation_Guide

I believe you will need to use the proprietary driver to get the best from your graphics card and monitor.

I followed the steps to install the fglrx proprietary driver (at a different place actually, here: http://wiki.debian.org/ATIProprietary), and everything immediately worked correctly. I was even able to get rid of the modeline and all the custom xorg.conf stuff I've been fiddling with and it still auto-detects it.

Thanks for your help!

Glad to hear you got it working!.
It would be useful if you use the thread tools at the top right of the page and mark it solved.

Ah, LQ has come a long way since I used to use it a couple years ago. I'll go do that now.
