Bug Description
With kernel 4.8-rc3, lightdm no longer starts if the modesetting driver is in use, because X crashes (I get the 'X is running in low-graphics mode' message). The modesetting driver works ok though with kernels 4.4, 4.6, and 4.7.
Using the intel driver it boots up fine (well, almost - the laptop screen turns off during login, so I have to type in my password blind, but then the laptop screen turns on and the desktop fires up).

Here's the Xorg.0.log from when it crashes. The initial error is "(EE) modeset(0): failed to set mode: Invalid argument".
