I don't know Linux from
Mannix but I do my best to keep an eye out for all Machinarium news out there on The Web...
Today I came across
this post wherein it said, "When I start the game I see a brief message 'Press ESC to leave full screen' and than nothing." after which the same person followed up with "Please ignore. Seems to be an
SELinux issue. Moved the game to home dir and reset the SELinux tags and the problem disappears."
Is this in any way helpful to you Linux Machinarium players?
