The kernel is unfortunately unusable with my external monitor because after some plug, unplug and suspend to RAM cycles the behaviour is not good (sometimes it freezes, sometimes X needs a restart). Sorry to ask, but is there someone looking at this? I can provide more information if necessary. On Tue, 9 Sep 2014 at 22:54:30 +0100, Carlos R.
