Changing resolution in X

Zuggy · 01-15-2005, 06:10 PM

I tried looking this up, but I'm in a hurry and couldn't find a quick answer.

How do you change the resolution in X. I just installed slackware 10 on my Vector Lappy and I need to set it to 640x480. Thanks for the help.

open up /etc/X11/xorg.conf

you will see a section that looks somewhat similiar to this :

Code:

Section "Screen"
    Identifier  "Screen 1"
    Device      "Standard VGA"
    Monitor     "My Monitor"
    DefaultDepth 16

    Subsection "Display"
        Depth       8
        Modes       "1280x1024" "1024x768" "800x600" "640x480"
        ViewPort    0 0
    EndSubsection
    Subsection "Display"
        Depth       16
        Modes       "1280x1024" "1024x768"
        ViewPort    0 0
    EndSubsection
    Subsection "Display"
        Depth       24
        Modes       "1280x1024" "1024x768" "800x600" "640x480"
        ViewPort    0 0
    EndSubsection
EndSection

now as you can see towards the top the "default depth" is "16", so the
only section out of all that, that will be used is the following because
as you see the depth is 16 for this section and that is default :

Code:

Subsection "Display"
        Depth       16
        Modes       "1280x1024" "1024x768"
        ViewPort    0 0
    EndSubsection

now when you look at the modes line you see that the first one
listed is 1280x1024, meaning that this is the resolution it will
load up to... so if you want 640x480 to be used, then put it
as the first option in modes ...
