I am sure that this is the driver. I use it before reinstalling the whole system (I use windows and Slackware with Lilo loader).
xorg.conf.fglrx-3.txt it my back-uped file. With it I have 1024x768
xorg.conf.txt is the conf file after I write
/usr/bin/atriconfig --initial and it make 1280x800
After doing theese stpes again I can't be able to end session neverthless wich conf file I use. First time it append theese screen (jpeg file)
2009-06-01-073.jpg
and the second time was nothing but black screen. I can't do anything but restart the computer.
I begin to think that anything with my filesystem is wrong. Few days ago I have to edit lilo.conf file, because it begin to appear third option when booting.
PS Linux loads in console, then I log in and startx to use GUI. End session return me in previous console.
My VC is Ati Mobility Radeon X1400 128Mb
For monitor I have no data but it support 1280x800 60Hz. I used it before in this resolution in Linux, but before reinstalling.
Just to clarify.
I didn't try catalyst, but I will try it if I can't get help. And last step is reinstall again
