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:
     • Section "Monitor"
       • Identifier "Monitor0"

         VendorName "Monitor Vendor"

       • ModelName "Monitor Model" HorizSync 30.0-85.0

       • VertRefresh 48-120

       • Option "DPMS"
     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"

         EndSubSection

     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: Adjust the Hsync and Vsync to higher values (some experimentation may apply if you do not know your monitors maximum value. BE CAREFUL!! Start low, and slowly move up) and simply add your new resolution value to the display mode.
