I have an HP Envy 14 with a Radeon HD 5650 and Intel switchable graphics. HDMI and DisplayPort output are only routed to the Radeon chipset. When initializing KMS for the Radeon card, I get a 1922x1080 output and the pink line on the left hand side of the connected monitor, regardless of the port the monitor is plugged into. This is very similar to Bug #27452 but the code change made there has no effect for me, hence this new bug. A quick google search didn't give me any pages that describe what other info I needed to provide as part of the initial report. Please let me know what information you need and I'll provide it as soon as possible.
Tried this again just now and all is working. *bangs head on desk*
