The method I currently use, does at least remove most of the buttons from the 
logout menu. But running devuan does carry the risk of having to deal with 
traditional tools not being updated due to systemd probably.

Nvidia does come with woes nowadays. Usually I get an error about 
nvidia-persistenced. It fails to start and clutters my apt/dpkg output. But 
as it doesn't run anyway and video works as expected, I have no troubles 
doing: apt purge nvidia-persistenced, as root.
