Comment 1 for bug 1348668

I have discovered that Dell has published a package here[1] which contains a deb package `workaround-screen-lock-malfunction_1_all.deb` that seemingly fixes this issue. Whether this is still a valid bug for the Unity lockscreen is difficult for me to say, but I will leave it as is, until someone more knowledgeable takes a look at it.

I was running a vanilla verison of 14.04 on the Dell XPS9333, with no special Dell packages installed when experiencing the lockscreen issue.
