I set it to /home/user/.Genymobile/Genymotion, but android-studio still can't find it. I've googled and can't find people talking about this topic (linux). The official guide said the path is /home/<user>/genymotion and I don't have that path. So where is it?
INFO: I'm running Arch Linux
I don't know where Arch usually puts installed packages, so I suggest you try to find the directory using the find command in the following places:
find /opt/ -iname *genymotion*
find /usr/ -iname *genymotion*
find /home/ -iname *genymotion*
