Display resolution on DELL Inspiron 8200

Hi

I'm a newbie using KDE 3.2.3
I'm running it on a DELL inspiron 8200
and my screen resolution which is normally a native 1400x1280 in WinXP comes up with a max of 1024x768 in KDE ?
Is it possible to manually specify a new hardware config/device to be considered by the system ?

Anybody has experienced similar problem ?
Tks for help

The config file you should look at is normally located under /etc. The exact location may depend on the distribution and the X server you're using. On my system (Debian, XFree86) it's /etc/X11/XF86Config-4 . I have KDE 3.3.1 running on a Dell Latitude 600 with a resolution of 1400x1050 (that's the "native" one on my system). I had to enter this higher-than-standard resolution manually, too.

Here's a snippet from my XF86Config-4. I left out the other color depths that I don't use. Be sure to modify the one that corresponds to your DefaultColorDepth (16 in my case). If I recall correctly all I did was adding "1400x1050" as first entry in this "Modes" line.

[code:1]
Section "Screen"
Identifier "Screen0"
Device "Card0"
Monitor "Monitor0"
DefaultColorDepth 16
[...]
SubSection "Display"
Depth 16
Modes "1400x1050" "1024x768" "800x600" "640x480"
EndSubSection
[...]
EndSection
[/code:1]

That worked for me, I cannot guarantee it will be that easy for you...

Needs SuperUser pwd...

Tks for help
Have tried the trick....

BUT when editing the XF86Config-4 file, i'm asked for a SuperUser pwd that I don't know.. I'm running KDE fron a bootable CD & save my customized parameters to Disk before I finish session.

Maybe I can't modified that file while running KDE from CD ?

I don't know how your bootable CD works but that surely complicates things... what distro is it, BTW? Knoppix?

- You could try the sudo command:
sudo vi /etc/X11/XF86Config-4
But even if that worked it wouldn't help if the file is located on the CD (it's not writable there...)
- You could check if your /etc/X11/XF86Config-4 is a just a symlink pointing to the file on the CD. I think that's how Knoppix does it. In that case you could remove the symlink and replace it with a real file (copy it from the CD and change it).

BTW: You may want to ask that question in a forum that is specific to your distro. I think you would have a better chance of finding someone who knows how to tweak your very distro. Maybe there's even a FAQ that explains it? (And this kind of problem is unrelated to KDE anyway...)
