I have recently just installed a new copy of Mandrake on my PC. It works fine apart from the screen resolution. I am able to set it to the moniters optimal : 1280x800, but all linux does is set it as a virtual resolution, so technically 1024x768 - but it overlaps. Does anyone know how I can fix this? I've seen loads of articles mentioning the editing of xf86config, but as my unsername suggests im not quite ready for this.
Anyone who can help, I will forever be in your debt.

If it helps im running a Proview widescreen EM-15W TFT off an Intel 810 chipset.

Thanks in advance biggrin.gif

You're totally ready. Trust me, it isn't hard, and I am going to walk you through it step by step for you.

First, open a terminal, or a console, they are the same thing, I just titles. In KDE you can go to Utilities and there is a terminal there.

Ounce you have a terminal open, you need to have root privilage so you can edit the config files. To get that type in the command su and then enter your root password when it prompts you.

Ok, you now have root privilage, no change directories over to /etc/X11 using the command cd /etc/X11 cd means change directory, and you can use this to navigate anywhere. A few extra nots for you just typing in cd will take you do the home directory for the user and typing in cd .. will take you up one level. So like say from /etc/X11 to /etc

Ok, now that your in /etc/X11 type the command ls to list out the files that are there. Linux (as a whole) is in the process of switching from X11 to Xorg so, depending on exactly which version you have, your going to either have a XF86Config file or a xorg.conf. You also might have a something like a XF86Config-6 file or something.

Before we edit anything, we are going to make a copy of the old file. Do this using the command cp XF86Config XF86Config.working that way, if anything goes wrong, you can just reverse the proccess and copy XF86Config.working to XF86Config and you will be back where you started.

Now open up which ever one you have in an editor like emacs, you can do this using the command emacs XF86Config A new window will apear with a lot of writting in it. This is the section of code you're looking for, it should be twords the bottom, yours will be somewhat different, but similar enought that you will recognize it.

Section "Screen"
    Identifier "Screen0"
    Device     "Videocard0"
    Monitor    "Monitor0"
    DefaultDepth     24
    SubSection "Display"
 Depth     16
 Modes    "800x600"
    SubSection "Display"
 Depth   24
 Modes   "1024x768"

Now, you will recognize the screen resolutions and they are in a SubSection with a Depth, what you either need to do is change the DefaultDepth to a subsection that has 1280x800 or you can change the current default depth Modes to "1280x800"

Ounce you have changed it, save it. Either by pressing F10,f,s or by foing File->Save of using the little disk graphic. Either way, save it. Now restart the X enviroment, either by logging out and back in, or pressing ctrl+alt+backspace.

You should be rolling. See that wasn't that tough now was it? And now you're one step away from being a newbie.
