I have to play Sublevel on Windows because on Kubuntu 18.04 (64 bit) I'm getting this error when trying to start it:

fane@fane-bestia:~/GOG Games/Sublevel Zero$ ./start.sh
Running Sublevel Zero
./SublevelZero.x86: error while loading shared libraries: libXcursor.so.1: cannot open shared object file: No such file or directory

In Muon I see that I do have libxcursor package installed, is it a matter of 32 vs 64 bit libraries?

Just bought the game. I am having exactly the same problem (currently running Linux Mint 19.1, 64-bit installation).

Update: I have now installed the 32-bit versions of the libraries listed on the gamecard, following standard procedure (e.g. " sudo apt-get install libxrandr2:i386", and so on). The previous error is gone, but the game crashes to desktop immediately after starting. Last line of console input simply states:
"support/gog_com.shlib: line 94: 3060 Aborted (core dumped) ./"${bin_64}"

Hey man, I appreciate your reply nevertheless.

Haven't been able to get this running properly on Ubuntu 19.04. Seems to hang on the unity, etc logo screen, but doesn't crash, and throws no errors. Anyone know a fix for this?

Running Debian "sid" here, and it's konking out on me as well. A GDB backtrace suggests it's dying trying to wait for a semaphore:

Never seen anything throw SIGPWR before...
