Whenever I try to boot linux with an external monitor attached to my laptop, it hangs after checking the battery state with the following message repeated several times:...crtc_helper_set_config...The only solution is to boot without the monitor attached, then attach it, and readjust my settings (turning off laptop screen, etc).  Some have told me this is a kernel issue, others just shrug.Any ideas for a solution?
