Comment 24 for bug 1311403

Removed 'duplicate' status as the fix committed in the bug this was marked as a duplicate of does not solve the issue described here. Confirmed with unity:amd64/trusty-security 7.2.2+14.04.20140714-0ubuntu1.1

I notice a significant number of Thinkpad owners appear to experience this problem - I am likewise on a Thinkpad W510.

In my case there is no 'gear icon' or any indicators visible at the lock screen, so the workaround in #23 doesn't do anything.
