How do I get a 1024x768 resolution?

[Stephen]

Hi y'all...

I'm a newbie with a newbie-question....

With some help from a more experienced Linux user I got my Daewoo monitor to run smoothly... (the autodetect didn't get it right) however it is running in 800x600 resolution and my monitor is able to run in 1024x768 resolution...

However, I ran the xf86config script yesterday (and set the monitor and gfx card) but I didn't get an option to choose a resolution...

I'm running Knoppix 3.3...

What do I do?

dpkg-reconfigure xserver-xfree86 gives you the opportunity but you may as well edit the file /etc/X11XF86Config-4 and put in your resolution there in the Depth subsection an example of the section in the file.

Section "Screen"
        Identifier "Screen0"
        Device     "Card0"
        Monitor    "Monitor0"
        DefaultDepth  24
#        SubSection "Display"
#               Depth     1
#       EndSubSection
#       SubSection "Display"
#               Depth     4
#       EndSubSection
#       SubSection "Display"
#               Depth     8
#       EndSubSection
#       SubSection "Display"
#               Depth     15
#       EndSubSection
#       SubSection "Display"
#               Depth     16
#       EndSubSection
        SubSection "Display"
                Depth     24
                Modes     "1024x768" "800x600" "640x480"
        EndSubSection
EndSection

You need similar in your file in the subsection for the DefaultDepth you are using. Then you need to restart the X server and see if it likes the new resolution with as root from the command line /etc/init.d/kdm restart or choose restart X server from the menu option at the KDE login screen. You should also have the proper refresh rates set for your monitor in the monitor section similar to this.

# Acer AcerView 54e
Section "Monitor"
        #DisplaySize      270   200     # mm
        Identifier   "Monitor0"
        VendorName   "API"
        ModelName    "4536"
        HorizSync       30-54
        VertRefresh     50-110
        Option      "DPMS"

A bit of searching should find the correct values HorizSync and VertRefresh if you do not have the manual that came with the monitor.
