Daniel: I updated my git repo and checked out version 10.1 (which is
what my install currently hast). I am still unable to repro the problem
from git checkout because the moment I start X with AccelMethod uxa,
the problem goes away.
Is there any better of testing this one library against an X
Note that this still happens on trusty with all updates installed as of

The laptop is doing a hybrid sleep: writing to disk and then sleeping to
RAM. It does not happen when I revert to the default suspend-only mode.
