https://bugzilla.kernel.org/show_bug.cgi?id=106271 Lukas Wunner <lukas@xxxxxxxxx> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |lukas@xxxxxxxxx --- Comment #3 from Lukas Wunner <lukas@xxxxxxxxx> --- The pitcairn GPU says "No connectors reported connected with modes". I suppose that's the discrete GPU? Does this machine have a hardware mux at all? If not, the discrete GPU can only be used to offload rendering and switching won't work. I guess the only thing that can be improved in this case is to make radeon_atpx_switchto() a no-op on muxless machines. If on the other hand the machine *does* have a mux, the question is why the pitcairn GPU didn't find any modes. Are there none in VBT? If so, the issue can probably be solved by temporarily switching DDC to the discrete GPU on probe. I'm working on patches to do that with apple-gmux on the MacBook Pro. -- You are receiving this mail because: You are watching the assignee of the bug. _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/dri-devel
