Version 0.1.0-1 of swappolube-nogui and all previous versions I posted on the forum had a problem in postinst (pointed out by Mikkov, and due to my ignorance ) and didn't uninstall the /etc/event.d/tuning script when the package was removed. This might be the reason why someone, even after uninstalling it, still enjoyed a well lubed GUI

I'm learning by copying other people's code - in this case I copied from shortcutd - and version 0.1.2 in extras-devel should be correct (hopefully), in that in uninstalls cleanly without leaving the tuning script behind.
Please report any problem you encounter in upgrading (of course if you chose the nogui version).
