[Intel-gfx] Disable connectors at compile time or runtime

2013-08-05 Thread Jan Niggemann
Hi all, I'm not using a docking station and would like to completely disable all connectors / ports except the internal laptop monitor. Can I do that with an option I pass to the driver through a kernel commandline, or do I have to do this at compile time? If so, how? I'd also be willing to
