Comment 11 for bug 1420290

I never close the lid immediately after booting, so in my case that cannot have been the cause.

So far I have not found a correlation between the intel drm flip error and things I did. Sometimes the error occurs after an hour, sometimes not for two days. Now it is even 5 days ago:
