Xsession

"keytouchd" needs to be started when the user starts an X-session. Some distribution have the directory /etc/X11/Xsession.d/ that contains the scripts being executed when an X-sesssion starts. If your distribution uses this directory I guess there will be no problem.

Other distributions do not have the Xsession.d directory and we will need to add a line at the beginning of /etc/X11/Xsession. Remove the following lines in keytouch-2.0/keytouchd/Makefile:

XSESSION_KEYTOUCHD_LINE="keytouchd &"; \
XSESSION_DIR="$(DESTDIR)/etc/X11/Xsession.d"; \
if [ -d $$XSESSION_DIR ]; then \
  echo "$$XSESSION_KEYTOUCHD_LINE" > $$XSESSION_DIR/40keytouchd; \
  chmod +x $$XSESSION_DIR/40keytouchd; \
else \
  XSESSION_FILE="/etc/X11/Xsession"; \
  if [ "`grep \"$$XSESSION_KEYTOUCHD_LINE\" \"$$XSESSION_FILE\" -m 1 -h`" != "$$XSESSION_KEYTOUCHD_LINE" ]; then \
    XSESSION_TMP=`cat "$$XSESSION_FILE"`; \
    echo "$$XSESSION_KEYTOUCHD_LINE" > $$XSESSION_FILE; \
    echo "$$XSESSION_TMP" >> $$XSESSION_FILE; \
  fi \
fi

Adding the line to /etc/X11/Xsession will be done during the post-install of your package (see section 6)
