ATI X300 and 24" Dell 2405 LCD Monitor

Hi all

I've just got my hands on a Dell 24" Widescreen LCD monitor (FPW2405). While it worked
out of the box at max resolution of 1900x1200 without installing the ATI 3D drivers for my ATI X300 card - as soon as I did install them, it would not go above 1280x1024. When I say this I mean the screen blanks out and says "Cannot display this mode".

My xorg.conf is below - the lines commented out are from the pre-installation of the ATI drivers. I've narrowed the problem down to the "screen" section - the pre ATI version does not work now.

I'm rather worried-I've just spent a small fortune on this screen! I'd rather not fork out on a new graphic card as well just yet ;-(

As ever, any help much appreciated:

Code:

Here I go answering my own questions again, I just could not let it rest, so here's the solution:

Code:
Section "Monitor"
 Option         "CalcAlgorithm" "CheckDesktopGeometry"
 DisplaySize    524 321
 HorizSync      30.0-81.0

 Option         "DPMS"
 VendorName     "Dell"
 VertRefresh    56.0-76.0
 UseModes       "Modes[0]"
EndSection

Section "Modes"

Hi all,

New guy here, first time post. Thanks a bundle to lacerto. I too have the 24-inch Dell 2405 with an ATI X600 (128Mb). I basically copy-pasted what lacerto posted here into my xorg.conf and it now runs in 1920x1200! For those other newbies (like myself), don't forget to install the fglrx (ATI X.Org drivers) unless you want to lose 3.5 days of your time...

Thanks again lacerto!

Glad it worked. I'm always particulary impressed when people take the time to post in just say to mention something works - it does not take much to do, and it really adds value to LQ.
