I installed the Linux version of Witcher 2 on Debian 11. I made sure to install the required Linux libraries listed on the game's page. The launcher starts, but the actual game will not start and causes this error: "ERROR - eON failed to initialise!"

After some research I saw that there's an error log for this ominous "eON". This is the content:

[code]
cat ~/.local/share/cdprojektred/witcher2/eon.txt

[/code]

What can I do to start the game without the error?

Solved: I found out I had to do

sudo apt install nvidia-driver-libs:i386
