Hello again,
I just installed a fresh Ubuntu 17.10, installed steam, lutris and winesteam. The last won’t start. I came till login then it crashes for no good reason.
Edit:
Native Steam don’t start with the error Failed to load steamui.so
When I start it without Lutris, it runs flawlessly
Ok, Now more Precise (Edit2): When I start Lutris I can start steam. When I then try to start winesteam, it goes till user configuration then crashes. Then I got the fatal Error when trying to start native steam through lutris. Till next reboot
