First, yes I did read
http://www.salixos.org/forum/viewtopic. ... 26&p=10590, but id did not help. I cold not run any "gtk 1360 768 60" to get a new screen mode, command not found.
Anyway, what I want to do is to get a resolution of 1440x900 on an Acer AL1916W on SalixXFCE13.37. The video adapter is a Geforce G72/7500LE and the driver loaded is noveau.
Just running Xorg -config and editing xorg.conf did not help much (I added vertical and horizontal refresh to the monitor section).
The problem is that I do not do things the right way. So, what do I edit and what do I put in there?

Oops. That should be gtf, not gtk.

I found out, but I still can not make it work...(setting 1440x900 as standard resolution, that is).
Should I make some extra files for xorg.d, and if yes, what should I call them?

If it doesn't work the way it's described, then it simply means that your graphics card/drivers do not support that resolution in any way.

You are probably right. I got the computer yesterday, and have not really checked what is inside...

Code: Select all
root[pelle]# gtf 1440 900 60

Modeline "1440x900_60.00" 106.47 1440 1520 1672 1904 900 901 904 932 -HSync +Vsync
root[pelle]# xrandr --newmode "1440x900_60.00" 106.47 1440 1520 1672 1904 900 901 904 932 -HSync +Vsync
root[pelle]# xrandr --addmode default "1440x900_60.00"
xrandr: cannot find output "default"
root[pelle]# xrandr --output default --mode "1440x900_60.00"
warning: output default not found; ignoring
I am getting the same with 1280x1024.
I think the computer has been originally delivered with a wide monitor (that is, that I am using the monitor it was delivered with), so the graphics card should support at least some wide screen resolutions. I tried 1920x1200 too. It is hard to find any specifications for the card (yes, I tried nvidia, google etc)

Your output name is not "default", it's "DVI-I-1".
