  • cd /usr/share/X11/xorg.conf.d

  • cp 10-monitor.conf ~/backup/10-monitor.conf.backup

  • add the following

        Section “Monitor”
          Identifier “Monitor0″
          Option “DPMS” “false”
        EndSection
    

  • in the Section "Screen", add the following

         Monitor	 “Monitor0″

https://wiki.ubuntu.com/Kernel/Debugging/Backlight

Your step for "allow to put computer into suspend mode" is missing the part about adding a line for the Monitor into the Screen section, as documented in Bob's original post. You might want to update that.

@pnkfelix, thanks, added

Can you explain how one can "steal" the ChromOS display driver for X and use it in Linux?
