Comment 28 for bug 1533221

I have the nvidia binary drivers installed from the graphics-drivers ppa.
I use prime-select to choose either "nvidia" or "intel".

Using nvidia boots fine. When intel is selected:
- lightdm greeter screen displays in low res (maybe 640x480, not sure)
- logging in simply returns to the greeter screen

Using this latest kernel, I have not seen any blank screens trying to boot with intel. But as per above, I can't log in.
