Certainly there are rough edges, but it looks like it will be useful...but for one problem. I can't reliably get it to sleep and wake.
I don't mean the "Sleep" and "Hibernate" options from the "Leave" menu--I have never gotten them to work at all. I'm just trying to get the "Off" feature on the Esc key to work. Or the lid close, either would do.
Trying to reproduce the problem I have had lots of theories of what exactly it takes to make it fail, but none seem to verify. The problem is frequent but erratic.
I do have a clue. The world map screen (the one with the various sized circles) where I type my password tends to do a brightness change; it appears bright, then I think adjusts to the ambient light. In the cases where I see it fail I think it does the same thing, but instead of adjusting to a new brightness it goes black. (No, I can't successfully type my password blind.)
When this does happen, I think the computer is still running, I think I have been ssh-ed in and that was still alive.
Any others had problems with the lockscreen and found what's the problem or a workaround?
