The screen will blank (screensaver of X?) in 10 minutes.
This is the default value of Xorg. This can be adjusted
my setting the Option "BlankTime" in the "ServerLayout"
Section.

So I changed '/etc/build_x4_cfg' from :

cat <<-EOF
Section "ServerLayout"
.....
     Option          "StandbyTime" "${X_DPMS_STANDBYTIME:-0}"
.....
EOF

into:
cat <<-EOF
Section "ServerLayout"
.....

     Option          "BlankTime"   "${X_DPMS_BLANKTIME:-0}
     Option          "StandbyTime" "${X_DPMS_STANDBYTIME:-0}"
.....
EOF


Could this be incorporated in the next release?
