<pre>It happens on every login. My user display configuration is such that it
switches the HDMI output on and internal LCD off, while the login screen
(lightdm) uses the internal LCD only. Immediately after logging in, I get the
display freeze when it tries to drive the HDMI output. The mouse cursor is
still moving.
Apparently the nternal LCD is driven by i915 directly while the HDMI output
goes via nouveau.</pre>
