Comment 173 for bug 1568604

I have tried both the ppa:oibaf/graphics-drivers repo, and the Xorg.conf.d method on my Asus S550CA, with Intel Ivybridge, and now the issue seems intermediate. It'll sometimes unlock, with the cursor visible, and sometimes it'll not show the cursor till I have issued the chvt 1+7 script to have it re-appear. So, between the two, there's something that is making it work sometimes, and not other times.
