Hi Maarten,
Our QA couldn't reproduce the issue here, Paulo couldn't reproduce the
issue as well. I tried with IVB, eDP+HDMI and couldn't reproduce.
Then I went to our lab and got a SNB with LVDS and DP, installed a fresh
14.04, configured the external monitor to the left side and waited 5
minute
I switched from a VGA to an HDMI cable. I have not encountered the
problem again since that switch.

Weirdly, this isn't happening as reliably as it used to. It still
happens, but not 100% of the time, so I've hard trouble capturing it.
I've applied some updates since I first reported it, so that may be
changing the behaviour somewhat. I'm definitely still seeing it - just
not every time.

To be explicit. We would like to obtain a system log with graphics

Hi Maarten - happy to do that, but I need more explicit instructions.

avoid that, I have now changed
Can you get the syslog while booting with drm.debug=6 added to the
kernel command line? That should get more information about the modeset
