--- Comment #24 from Denis Reva <denis7...@gmail.com> --- I have found a suspicious piece. Under normal user `eglinfo -B` shows: GBM platform: _amdgpu_device_initialize: amdgpu_query_info(ACCEL_WORKING) failed (-13) amdgpu: amdgpu_device_initialize failed. _amdgpu_device_initialize: amdgpu_query_info(ACCEL_WORKING) failed (-13) amdgpu: amdgpu_device_initialize failed.
