Widescreen TFT

ivers · 03-23-2004, 05:07 AM

I got this laptop with a 15,2" Widescreen TFT monitor that can do 1280x864.

I've only managed to achieve 1024x768, and gnome looks ugly.

Is there anyone who knows what to do to get xfree to start with 1280x864 ?

I've tried to set colors to 16/8/4 bit but that's not working.
Modelines, Options, alot of them eg.

Help ?

Did you try to set the default mode to 1280x864 in your XFree86 config file (usually /etc/X11/XF86Config-4)?
Something like this should do if you have DefaultDepth set to 24:

Code:

        SubSection "Display"
                Depth     24
                Modes           "1280x864" "1024x768" "800x600"
        EndSubSection

Yes, but I get

Code:

screens found, but none has a usable configuration

I've tried this too:

Code:

Section "Monitor"
        Identifier   "Widescreen"
        VendorName   "Monitor Vendor"
        ModelName    "Generic Laptop Display Panel 1280x864"
        HorizSync    31.5 - 67.0
        VertRefresh  50.0 - 71.0
        Option      "dpms"   
        ModeLine "1280x864" 65.00 1024 1032 1176 1344 480 488 494 563 -hsync -vsync
EndSection

Can we have some more info please, like the exact model of your laptop and your video card. It would probably help.

I don't have the nVidia driver here on this box but check the documentation for it, it might mention what modes are supported and how to set them correctly.

I did

Doesn't help.

This is a modeline problem.

You need to create a useable modeline for that resolution in the section with everything else. That modeline must specify the starting position and range of the display at the proper frequency. If the frequency is off, then a mode might not be useable by XFree86.

Do a google search for linux modelines.

A display like that is non-standard and needs a fair amount of tweaking.

Yes, I noticed. Now it says hsync is out of range.. wooo - progress!

Code:

Modeline "1280x864" 87.76  1280 1328 1440 1632   864  864  866  896

Try here:

http://www.dkfz-heidelberg.de/spec/linux/modeline/

If you look at your logfile, you will notice the nVidia drivers are changing the horizontal and vertical refresh frequencies. Set new ranges in the calculator and adjust your XFree86Config file accordingly.

If this calulator doesn't work, try looking for another online.

That is just the one I'm experimenting with.
