I'm running Archlinux 2012 - kernel 3.6.9-1-ARCH
When plugging two monitors (the third one is laptop's LCD) x server fails to
start and shows "[drm:drm_crtc_helper_set_config] *ERROR* failed to set mode on
[CRTC:7] on two monitors and turns off the third one.
I'm using intel core i7 3612qm (Ivy bridge) and according to inel
Specifications at <a href="http://ark.intel.com/products/64901">http://ark.intel.com/products/64901</a> , inel hd 4000 supports
up to 3 monitors.
