--- Comment #1 from Alex Deucher alexdeucher@gmail.com --- Please attach your full dmesg output (I couldn't find it on the other bug report). Note that the AMD card is not connected to the laptop panel. The AMD card is purely for offload rendering (e.g., AMD card renders a game and then the frame is sent to the Intel card for display).

--- Comment #2 from brent s. brent.saner@gmail.com --- Created attachment 154051 --> https://bugzilla.kernel.org/attachment.cgi?id=154051&action=edit dmesg output on 3.16.4-1

--- Comment #3 from brent s. brent.saner@gmail.com --- Dmesg output attached.
The panel isn't attached to the AMD card? The ACPI issues in the other bug seem related to AMD, and it affects the display, even in TTY, so I had thought otherwise.
Let me know if you need any other output

--- Comment #4 from Alex Deucher alexdeucher@gmail.com --- The radeon driver has initialized fine. There are no displays wired to the radeon card at all. It's purely for rendering offload. If you are not getting a display it's an issue with the intel driver.
