I'm setting up a Kerbal Space Program install on Ubuntu Mate 16.04, and one of the mods I have installed (Principia -- makes the game gravity act like real gravity) can't find its
principia.so unless the working directory is the same one the game is installed in.
Unfortunately, I learned a few months ago, when I installed 16.04 MATE, that the Mate desktop launchers don't support compound commands (like
cd /home/username/KSP-RO_1.3.1 && KSP.x86_64), and seem to offer no provision to change the working directory from the launcher properties. KDE launchers do (or did, in 14.04; I haven't used Kubuntu 16.04 much) allow specifying a working directory; is there a way to do so in a MATE launcher?
