Comment(by pgf):

 referring to a test entered at #8893:

 {{{
 while true; do
         echo 1 > /sys/devices/platform/dcon/freeze
         sleep 0.2
         echo 0 > /sys/devices/platform/dcon/freeze
         sleep 0.2
 done
 }}}

 the pulsing or flickering effects of this loop can be greatly reducedy by
 changing the "resumeline" parameter to the dcon driver:

 {{{
 echo 400 >  /sys/devices/platform/dcon/resumeline
 }}}
 (the default value is 898.)
