First of all Latest is rolling with updates, not RC2.
Autostart script ~/.config/openbox/autostart requires creating ~/.config/openbox/
dir and works only in openbox-session. ~/.profile can be useful to add commands in it.
lxde-session uses autostart from *.desktop
files in directories:
systemwide: /etc/xdg/autostart/
user's: ~/.config/autostart/
[Desktop Entry]
Type=Application
Name=script
Exec=/path/filename
Then check for it in lxsession-edit.
In slitaz4: opening autostart-script without mkdir, old lxsession-edit (or something simalar) had 'add' button. For those who wants add-button it's possible to use /usr/bin/lxqt-config-session
from lxqt-session package. I just built lxsession 0.4.9.2 (gee1.0=0.6.8) with its lxsession-edit - nothing new, except new bugs and +200K to stripped binary. Maybe it's a good idea to create default ~/.config/openbox/autostart with #solution.
