Maybe! Would that device have some sort of interaction with X one way or another? Because it seems that I can reliably suspend/resume if xenodm is on the login page, but after I've logged in via xenodm, suspend rarely works and, if it does, resume almost certainly doesn't. As that suggest, I haven't got a clue where to start with this! Laurie
