Laptop resolution issue w/ Nvidia


Okay, I know questions like this get asked all the time, but, believe me, I've done hours of research, and nothing has helped. Maybe someone can give me the answer or at least a fresh perspective, please?

I installed Fedora 3 on a Toshiba P25 laptop. It has a 17" widescreen at 1440x900 and a 32mb Geforce card of some type. The "nv" drivers wouldn't allow me to use that resolution, even when it was in the appropriate place in the xorg.conf file. It always defaulted to a lower one. If i remove all other resolutions except 1440x900 from xorg.conf, gnome appears to start, but the monitor displays either nothing or rows of white lines. This happens in 16 and 24 color modes.

I installed the nvidia drivers, which went well, but these drivers refuse to allow any resolution above 1280x1024.

Is there something special I need to do to allow "nonstandard" resolutions? I was thinking of putting a modline in the conf file, but I have been unable to find any information whatsoever about my monitor.

The relevant portion of my xorg.conf:

Code:
Section "Monitor"
	Identifier   "Monitor0"
	VendorName   "Monitor Vendor"
	ModelName    "LCD Panel 1440x900"
	HorizSync    31.5 - 100.0
	VertRefresh  50.0 - 100.0
	Option	    "DPMS"
EndSection

Section "Device"
	Identifier  "Videocard0"
	Driver      "nvidia"
	VendorName  "Videocard vendor"
	BoardName   "NVIDIA GeForce FX (generic)"
EndSection

Section "Screen"
	Identifier "Screen0"
	Device     "Videocard0"
	Monitor    "Monitor0"
	DefaultDepth     24
	SubSection "Display"
		Viewport   0 0
		Depth     16
		Modes    "1600x1200" "1400x1050" "1280x1024" "1280x960" "1152x864" "1024x768" "800x600" "640x480"
	EndSubSection
	SubSection "Display"
		Viewport   0 0
		Depth     24
		Modes    "1440x900" "1400x1050" "1280x1024" "1280x960" "1152x864" "1024x768" "800x600" "640x480"
	EndSubSection
EndSection
Thanks for your help.

Yup, you need to write the modeline for non-standard resolution. There are a lot on google, but you should check with the max frequency of your screen...
I found two by looking at google but use one of them *only* if it corresponf to the right frequency!
Modeline "1440x900" 106.47 1440 1520 1672 1904 900 901 904 932
Modeline "1440x900" 100.00 1440 1500 1508 1512 900 916 924 940
Good luck!

My problem now is I can't find the frequency values for my screen. I've looked. I guess i'll search some more and see what comes up. Would i really hurt anything if I just tried those two modlines and see what happens, I wonder? Thanks for the help.

I would try one with a frequency of 60Hz, you won't be talking much risk... but do it at your own risk though ;-)
Good luck!
