Dynebolic 2.4.2. Screen Configuration

This page covers any issues related to Screen configuration

  1. I want to change my display to a format not available in the Dynebolic configuration (Configure/ Interface/ Display menu)
    • There are many web sites that outline changing the display. For example, you may want to change the refresh rate to a setting not available in Dynebolic. A simple method is as follows
    • a. Find your monitors Vertical (Hz) and Horizontal (kHz) sync rates

      b. Go to one of the websites that generates a Modeline for X, for example: http://xtiming.sourceforge.net/cgi-bin/xtiming.pl

    • c. Follow the instructions and fill in the blanks and generate an appropriate modeline for your monitor
    • d. Login to Dynebolic as root and open the /etc/X11/xorg.conf file for editing, ie:
      • # nano /etc/X11/xorg.conf
      e. Find the point in the file titled "Monitor" and add the Vertical and Horizontal sync ranges as follows: f. In the same section find the part that has all the monitor modes and add in the generated Modeline as follows (for example):
      • ModeLine "1280x1024@50" 90.89 1280 1312 1656 1688 1024 1045 1054 1076 +hsync +vsync

      g. Go to the section that is titled "Screen", and add in the part from the Modeline in inverted commas ie "1280x1024@50" to the start of the line titled "Modes" in the subsection "Display" that corresponds to the default depth as shown below:
      • Section "Screen"
        • Identifier "Screen0"
        • Device "VGA"
        • Monitor "Monitor0"

          DefaultDepth 24

        • SubSection "Display"

          • Depth 24 Modes "1280x1024@50" "1024x768" "800x600" "640x480" "1280x1024" "400x300"


      h. Save the file (Ctrl-O in nano) and then exit X (Ctrl-X) and then restart X (startx). Your display should now be running with the new mode you have set.

To allow higher resolutions: Add your new display resolution to Display section and "modes".

Adjust HorizSync and VertRefresh to allow higher values. Work your way up slowly.

Close X with ctrl-alt-backspace, then startx to start again.
