How to Install HD2 on Linux

I'm wondering if it can be something related to permissions

My last update 2 weeks ago created some problems. More specifically H&D2 and Mafia no longer worked, while Vietcong worked fine. I had a segmentation fault (core dump) which I debugged and it was coming from some .so file related to the lib32-nvidia-340x-utils (32 bit package for my old video drivers, no longer maintained by nvidia but by the Arch community). I removed that package and everything was working, but running like hell. The setup.exe file showed a different video card than what I had.

After some research, I found some problems created by the glibc library. Out of nowhere I did another system upgrade. This time it didn't remove my dkms package but I reinstalled the video drivers and 32 bit libraries anyway. Everything fixed itself!

P.S. For some reason I couldn't uninstall H&D2 with wine. It was working somehow, but it wasn't being removed. I installed the game in its own prefix.

I've just seen a reddit thread with a similar issue on Linux Mint, just another game. There was no useful answer.

We should try to debug it together. I'm thinking of avoiding Steam or even installing the game from ISO files to rule out any problems with the game itself from Steam or GOG.

gamemode has improved gameplay significantly! Thank you Damni
