Hello @Datamats, what DDX are you using? When used with AMD graphics, SteamVR direct mode currently needs either xf86-video-modesetting from xorg server 1.20.1 or a git master build of xf86-video-amdgpu which is newer than 2018-07-10.

Thanks @kisak-valve! After compiling the master of xf86-video-amdgpu and installing it everything started working.

@Datamats how would you go about compiling and installing it? Because I tried to and obviously did something wrong as it bricked my system

Nothing extracted yet.
