Since updating to Ubuntu 18.04, I've been unable to run The Witcher 2 until today. Attempting to launch the game from a terminal yielded a libdbus error and a core dump upon clicking play in the launcher.
I managed to get it to run successfully today by copying libdbus-1.so.3 from the Steam runtime at ~/.steam/ubuntu12_32/steam-runtime/pinned_libs_32/ to ~/GOG Games/The Witcher 2 Assassins Of Kings Enhanced Edition/game/
I assume the new version of this library has broken compatibility. I've opened a ticket with support so we can hopefully have a solution that doesn't require installing Steam, but I thought I'd post this workaround in case anyone comes here looking for a solution to this issue in the interim.
