--- Comment #1 from Jason Vas Dias <jason.vas.dias at gmail.com> --- Next steps: hacking X-Server & kernel drm & dri code to emit more debug log messages . Any suggestions as to how to bring up an X-Server on Radeon 8970M card when Intel i915 IGP is active under Linux 4.5+ ? I would have thought X-Server v1.18.3 should be capable of detecting if it needs to use vga_switcheroo and be able to use it automatically by now - but apparently not ; and it seems impossible to get the X-Server to work (via libfb) without doing a vga_switcheroo . I think the kernel needs a way of specifying an initial vga_switcheroo/switch state at boot, like: 'vga_switcheroo=DIS:Pwr;IGP:Off' . -- You are receiving this mail because: You are watching the assignee of the bug.
