Ganni1987: I know what your problem is with the game and I had the same trouble just less messy.
go to my ftp server: [url=ftp://88.203.18.13/pub/software]ftp://88.203.18.13/pub/software[/url] (if it asks you for a username just type: anonymous and leave password blank.
Download the: witcher_2_libraries_linux_mint.tar.gz file and extract it into your "game" folder where you installed Witcher 2.
The game will run fine afterwards :D
Basically I created this fix myself for Linux Mint 64bit (haven't tested 32bit) to avoid going through all the trouble. It used to stop working right after the Launcher for me as well but after adding the missing libraries it ran fine, (I'm at Chapter 2 in the game so it works).
BKGaming: Thank you, I don't normally like downloading things from unknown sources (can't be to careful) but I am ready to try just about anything at this point in time.
Why do I get this nagging feeling GOG rushed the Witcher 2 Linux version to the site and we are all playing beta testers now. No deb installer, hard as hell to get working.... seems not ready to me.
I understand you perfectly, the file contains the necessary libraries to get the game running. I myself broke like 5 installations of Mint before completely removing Windows and started using Linux as my only and main OS. It was well worth the effort though.
I'm unpacking Witcher 2 as we speak to make sure I didn't miss any details, so keep this page refreshed :P
UPDATE:
Ok so As I was saying, I unpacked the game from fresh and tried to run it in terminal, got to the launcher and I hit play and in terminal I got this:
"./witcher2: error while loading shared libraries: libSDL2-2.0.so.0: cannot open shared object file: No such file or directory"
My next step was to unpack the tar.gz file I linked you in the folder named "game" where the game is installed and tried to launch the game again, waited a few seconds after I hit Launch game and it ran.
So I guess I didn't miss anything, one last thing: When you close the game a crash dialog will popup, there's nothing you can do about this, it's something the porting team has to fix but don't worry the game runs fine nonetheless. ;)
