How to disable Framebuffer

  • Modifying the Grub menu:
    1. Open the Grub menu file (IE. /boot/grub/menu.lst) in a text editor.
    2. One of the following options should disable frame buffering:
      • vga=normal
      • nofb
      • nomodeset
      • video=vesafb:off
      • i915.modeset=0
    3. You would specify one (or more) of the above on the ‚kernel‘ line of the Grub menu file. You can specify them all instead of trying each individual one.
  • Disabling the KMS (Kernel Mode Setting):
    1. For Debian Wheezy systems with an AMD/ATI video chipset and driver, you can disable the KMS (Kernel Mode Setting), and thus the frame buffer. First, open the /etc/modprobe.d/radeon-kms.conf file in a text editor.
    2. Add the following line to the file:
      • options radeon modeset=0
    3. Save the file and exit from the text editor.
    4. Reboot the system for the change to take effect.
      • (Note: For nVidia based cards, add „nomodeset“ to the kernel command line (in /etc/grub.d/10_linux), as the first solution above suggests.)
