ati dual screen seperate resolution + NIGHTmares!

[coloured]

this may not be exactly related to jaunty, but I am using jaunty so I will post it here.
I have an ati 2600 card in my laptop
the res of my laptop is 1280x800
the external lcd has a res of 1280x1024
I have the ATI fglrx driver installed from the repos
I have the display stretched over both screens
the res on the laptop is good 1280x800
but the res on the external lcd is b*orked I guess it is also trying to run at 1280x800
how can I change the res of the external lcd independently? this used to work in hardy and intrepid when I used envyng to get the driver and used catalyst to set big desktop
here is my xorg.conf

well I finally figured out how to get seperate resolutions while having the desktop stretched across both screens.... after a lot of d*king around with xorg.conf and a bizillion reboots into recovery mode to overwrite the b*orked xorg.conf file.

I will post the fix tomorrow for anyone who is having the same problem

*** 1 question remains ***
with my previous setup when I maximized an application window, firefox or terminal or gedit etc... it would only fill the screen the app is on, since I have fixed the problem within jaunty when I hit maximize it fills both screens.

Anyone got any helpful hints as to what I should do to resolve this? its very annoying

cheers

I look forward to seeing your fix. This has been giving me fits as well.

Unfortunately I dont have the time to work through exactly what fixed the problem this morning... But I will post my xorg.conf file along with the links I used to fix this problem. Again I am still having problems with maximizing windows (they will not maximize to cover only the screen they are on, but rather fill the entire virtual screen)

below is the link I used to resolve this issue.

I apologize that I can't show an exact fix.... I have some important work due in 8 hours.
After that I will revisit this.
