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:
However, when I restart X with this configuration, I get the following messages in my /var/log/Xorg.0.log:
Code:
<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.
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:
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.
