I found I have the exact same bug, and that my laptop, a Dell Inspiron 5548, is similar to one mentioned in an article which led me here. I discovered the problem on upgrading to 15.04, from 14.10. If I can provide any system information which can help the problem's identification, please tell me what to do.
