Screen Resolution on a Dell Inspiron 1100


Hey there.

I have a Dell inspiron 1100, and i just installed Fedora Core 4 on it yesterday. The computer has 512 mb of ram, 30gb HD, and BIOS A32.

The problem is that the screen resolution is set at 640x400, with no way to change it in any of the menus.

I'm a hopeless noob, and have no idea how to fix this. If someone could give me step by step way to fix it, it would be great. thanks in advance for any help.

You could manually enter the resolution in the xorg/XF86 config file. I am not sure which one of the two x-servers, Fedora Core 4 uses, but its not hard to find out.

Code:
cd /etc/X11
If you see an xorg.conf file then you are using xorg if you see an X86Config-4, then you are using XFree86.

Code:
vi xorg.conf
or
Code:
vi X86Config-4
Navigate to this section in your config file, where it says modes, just enter the resolution that you want in quotes. When I do it this way I add the resolution to all the color depths. to save your changes in vi, hit ESC then Shift + : and then type wq

Code:
ection "Screen"
        Identifier      "Default Screen"
        Device          "Intel Corporation 82815 CGC [Chipset Graphics Controller]"
        Monitor         "DELL M990"
        DefaultDepth    24
        SubSection "Display"
                Depth           1
                Modes           "1024x768"
        EndSubSection
        SubSection "Display"
                Depth           4
                Modes           "1024x768"
        EndSubSection
        SubSection "Display"
                Depth           8
                Modes           "1024x768"
        EndSubSection
        SubSection "Display"
                Depth           15
                Modes           "1024x768"
        EndSubSection
        SubSection "Display"
                Depth           16
                Modes           "1024x768"
        EndSubSection
        SubSection "Display"
                Depth           24
                Modes           "1024x768"
        EndSubSection
EndSection
Here is an example of my modded config file with my x-server running at 1280x1024

Code:
ection "Screen"
        Identifier      "Default Screen"
        Device          "Intel Corporation 82815 CGC [Chipset Graphics Controller]"
        Monitor         "DELL M990"
        DefaultDepth    24
        SubSection "Display"
                Depth           1
                Modes           "1280x1024" "1024x768"
        EndSubSection
        SubSection "Display"
                Depth           4
                Modes           "1280x1024" "1024x768"
        EndSubSection
        SubSection "Display"
                Depth           8
                Modes           "1280x1024" "1024x768"
        EndSubSection
        SubSection "Display"
                Depth           15
                Modes           "1280x1024" "1024x768"
        EndSubSection
        SubSection "Display"
                Depth           16
                Modes           "1280x1024" "1024x768"
        EndSubSection
        SubSection "Display"
                Depth           24
                Modes          "1280x1024"  "1024x768"
        EndSubSection
EndSection
Restart the x-server and you should be good!

I changed xorg.conf as you suggesr and added all the other resolutions available on my laptop. I rebooted Linux (RHEL WS 4.0). But that did not seem to work. When I go to "Applications->Preferences->Screen resolution", the popup it is still showing me 2 resolutions (800x600 and 640x480). Should it show the other resolutions in the list? Where should the modifications to the xorg.conf file show up?

The one difference between your case and mine is that I have RHEL WS 4.0 as a guest OS with VMWare interfacing on top of a WINXP-Pro host. Would that make any difference?

Would appreciate any help on this.

Thanks in advance.

I am guessing that running the setup the way you have it might be the culpirt. I am not familar with the program that you are using, but is it possible that it only allows you to run OSs at a certain resolution?

It's probably the same problem FC3 has...it assumes a low-res monitor by default. The solution is to change the monitor on the middle tab (in the same menu you use to change resolution).

There have two way to cause this problem, one is vga driver and second is monitor driver. so first, you must check the monitor setting in /etc/X11/xorg.conf, you can set the modeline of your monitor, then you can check the vga driver on /etc/X11/xorg.conf too.
