I reverted the offending commit in the v3.16-rc5 branch and it seems to fix the problem. Specifically, in the file drivers/gpu/drm/i915/intel_dp.c near line 1902, under function : static void intel_disable_dp(struct intel_encoder *encoder) I changed line 1912 from: intel_dp_sink_dpms(intel_dp, DRM_MODE_DPMS_OFF); to: intel_dp_sink_dpms(intel_dp, DRM_MODE_DPMS_ON); And that seems to fix the problem. How do I proceed from here? ** Tags removed: needs-bisect raring ** Tags added: bisect-done -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1343543 Title: [Dell XPS 15 L502X] X stops responding to input after entering idle power saving (screen off) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1343543/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
