I have a problem concerning Amnesia: The Dark Descent bought in Humble Indie Bundle V. The game crashes when I hover over notes, and so does Ubuntu. After the crash I can only see the desktop background, and the only way out is a restart.
As I can't find anything concerning this particular problem, I try to follow the Frictional Games' troubleshooting guide. In G-1 it says:
Make sure Amnesia has full disk read/write permission in the directory it is installed.
How do I do it?
