4200 on Dell I8500 resolution problem
 
1 Attachment(s)
I've been able to get my xserver running with some help from folks here, but it's still not at full resolutoin. It's only going to a measly 1600x1200. The LCD is capable of 1920x1200.

I updated the XF86Config but there is a funny line the the log when i bring up x:

(II) NVIDIA(0): Not using mode "1920x1200" (no mode of this name)

And the configuration

Does anyone have either this configuration, or at least something with greater than 1600x1200 working. Maybe simply looking at your XF86Config-4 would help me out.

Thanks.

I think that for a mode that high (since there aren't any VESA standard ones that X knows about inherently), you have to write your own mode line. If you have X 4.3.0, you can use the gtf command to do this (gtf takes a horiz. res, a vert. res, and a vert. refresh rate as separate options on its command line); if not, there are a couple of utilities that'll do it for you, linked off the XFree86-Timings-HOWTO at www.tldp.org

Hmm, that howto implies that if I have a resolution below 1920x1440 (which I do) then XFree86 will handle it.

Does this change your advice any?

It may not handle it correctly. You should guarantee that you have a good mode by using a modeline. 'gtf' (shipped with X 4.3) will generate a modeline for you. FWIW, i've got an 8500 working with 1920x1200 without problems using:

Code:

        Modeline "1920x1200"  162 1920 2020 2052 2184
                              1200 1202 1208 1235 +Hsync +Vsync

However, you should make sure that this modeline is appropriate for your system before trying it.

Nope. ;)

Supposedly it worked in XFree86 4.2.0 at 1280x1024 at refresh rates up to and including 80-some Hz refresh rate (at least, I remember reading this somewhere). However, without a modeline, I couldn't get it higher than 60Hz. :) Follow Andy's advice.

Thanks to those in this thread for the help. I'm running at 1920x1200 now and happy as a clam.

I've owned four machines now with nvidia adapters and bought this laptop *because of it*. Linux support is the reason why.

Hi,

I am new of linux and i just bought a dell inspiron 8500. I really appreicate that you guy can help me out to setup the nvidia video card and the LCD screen that support 1920x1200.

Please help me out, thanks

I know you guys get it working.

Thanks for you time

I created a modeline for the 1680x1050 LCD panel on my Dell 8500. I did it by hand, respecting the constraints in the NVIDIA readme, and it works well. Here it is:

Modeline "1680x1050" 115 1680 1712 1736 1752 1050 1053 1056 1093

You may also want to tell the NVIDIA driver to mantain aspect ration when scaling lower resolutions using the following option on the device section:

Option "FlatPanelProperties" "Scaling=aspect-scaled"

BTW, I thought refresh rate did not apply to LCD panels? I did the math for a "60Hz" vertical refresh to make X happy but I don't think it makes any diference, does it?
