The upstream bug report hasn't imported the new comments yet, but they found this was related to https://bugzilla.kernel.org/show_bug.cgi?id=47641 also so it broke dithering on a HP EliteBook 2540p. Intel has reverted this commit with http://cgit.freedesktop.org/~danvet/drm- intel/commit/?id=2f4f649a69a9eb51f6e98130e19dd90a260a4145 (which is not yet in Linus' tree yet) because it broke more than it fixed and they need another workaround for the one machine it did fix. ** Bug watch added: Linux Kernel Bug Tracker #47641 http://bugzilla.kernel.org/show_bug.cgi?id=47641 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1070978 Title: eDP laptop screen does not come up until a suspend/resume cycle happens.
