dmesg with drm.debug=0x1e log_buf_len=1M, two attempts at [   89.938216] and [ 
148.551328]

When I close my lid while plugged in, the screen goes black (which is
expected).

When I open it again, it stays black (not expected I think) and is only revived
when mouving mouse or doing other input events.

When looking at the log, I see things like that:
