That doesn't seem to give me any output at all.

One thing I noticed, though, is that I occasionally get something like:

Aug 23 17:43:14 bike kernel: [ 142.920185] [drm:intel_calculate_wm] *ERROR* Insufficient FIFO for plane, expect flickering: entries required = 51, available = 28.

They seem to come in threes, for whatever that's worth.

Thanks,
