<H2><A NAME="s6">6. Automating the process</A></H2>
<P>This small script automates most of the work. Be very careful with the
ScanType and with the two Polarity lines: the script do not set them
and, if you are too lazy to correct them, the risks of blowing up your
monitor increase quite a lot.
<P>Notice that I don't know if the 'Doublescan' flag has meaning in XInside:
if you try to convert a low-res doublescan mode BE CAREFUL, you can easily
kill your monitor since the refresh rate that you get is doubled ( in
fact my 400x300@72Hz became a 400x300@144Hz !).

# XF2XInside
#
# This script converts modelines from XF86Config format to XInside
# format as needed for the etc/Xtiming file.
#
# This is a quick hack, so don't expect much error checking (not to
# speak of anything like user friendlyness).
#
# If you call it without arguments it should tell you what to do.
#
# ( July 1996, hcz@tazlwurm.bb.bawue.de)
#
# Btw: New modes created as described in the HOWTO work, but don't
# show up in Xsetup's menu. Anybody who knows why?
