Connector info
--------------
connector 29: type VGA-1, status: disconnected
modes:
connector 32: type HDMI-A-1, status: connected
and no mode set in x (i.e. HDMI1 connected but not enabled), I see lots of
corruption on the HDMI display. In places it looks like PTE values, but
inconsistent - possibly ringbuffers?
