if you want to launch livarp in single-session without uninstall/delete anything, use ~/.xinitrc instead. visit the dedicated page.
livarp_0.3.9 includes a script that can delete all sessions but one: your livarp becomes a livarp-xs.
Warning: this script is launched as root and delete all system/user files and directory from unselected sessions.
Warning: be sure to be conected to the session you want to keep when launching livarp-xs-maker.
livarp-xs-maker is launched from the different livarp menus:
root password will be asked, then a dialog client pop-ups to let you select the session you want to keep.
a dialog client pop-ups at the end of the script:
on next login, the selected session will be launched in auto-mode: welcome to livarp-xs :)
