`i915.disable_power_well=0` does not help, ie.:
```
$ dmesg|grep -e '0000:00:02.0' -e 'i915'

```
at [ 220.715002] I pressed Ctrl key to wake up the software but the monitor
was still off! got the ret=-110 messages.
10 seconds later(so at [ 232.057307] I'm guessing) I turned on monitor, got
the normal ret=5 messages.
`drm.debug=0x1e` spews just too many messages, not sure what to do with it...
not even sure if it would log all of them during the test or they would just
get overwritten due to the ring property of the dmesg(kmsg?) buffer. Maybe I'll
retry.
