--- Comment #32 from Tomas Janousek <tomi at nomi.cz> ---
I was experiencing the same issue with a ThinkPad 25 (which is almost the same
thing as T470) and I implemented these precautions as a workaround:

- disable DPMS when docked and external monitors enabled
- never switch VTs with external monitors enabled
- always disable external monitors before suspending or undocking

Posting here just in case someone is still suffering from this and hasn't
figured out a workaround yet.
