9.04 Dell C640 ATI 7500 Radeon Resolution "stuck" at 1024x768

[Rustig]

After reading multiple threads and trying 3 different howto's, reinstalling Ubuntu for the 5'th time.

I realy like to shout out, can someone help me getting a better resulotion than 1024x768 on my Dell C640 ?

It seems that in Ubuntu 6.10 this was no problem: http://ubuntuforums.org/showthread.php?t=429425

I am understanding the /etc/X11/xorg.conf and i'am also able to analyse the /var/log/Xorg.0.log

Installed the radeon driver fron catalyst 9.3 This one is able to play with my ATI 7500 I can see in the log file that the correct driver is loaded, no errors at that point. I used this procedure: http://wiki.cchtml.com/index.php/Ubuntu_Jaunty_Installation_Guide#Installing_the_dr ivers_manually

What i thought i would be: the display max resolution is set to 1024x768 via the BIOS of the machine. So i added a extra line in xorg.conf -> in device: Option "PanelSize" "1400x1050"

This results in a bigger panel screen layout, i mean i now can choose the 1400x1050 resolution but it just magnifies the desktop, i hoped the txt and icons would be smaller with this resolution :(

When i used xrandr to change between resolution this also dont give the good resolution :(

Maybe someone who ownes a C640 does know the resolution.

Thanks in advance,
Regards,
Mike

PS: i can post my xorg.conf and Xorg.0.log

I added the log and xorg.conf in the packed file.
