Hi Dave, The following behavior is observed on BDW for MST using drm-nightly kernel:
1. Connected boot: Display comes up on MST panel but the system is driven to low graphics mode (command line), i.e. UI doesn't come up. 2. Hot plug: No display on MST panel. My top of the tree for drm-nightly is: Commit ID: 17874a0bd04949ab460431e6017860ab98e0e4d2 Author: Ville Syrjälä ville.syrj...@linux.intel.com<mailto:ville.syrj...@linux.intel.com> drm-intel-nightly: 2015y-11m-26d-16h-57m-42s UTC integration manifest Request you to kindly confirm this behavior for MST on BDW. P.S: We are observing the same behavior after applying the reorganization of DP HPD handling patches. Thanks and Regards, Shubhangi Shrivastava.
