Nov 23, 2014 8:03 AM in response to vitorgby dsabolo,Hi,I hope this can help. I´ve changed the permissions and reseted the SMC and PRAN with no success. Then, I´ve installed the driver from Display Link it seems to fix the problem.
The driver is here:

Nov 23, 2014 5:25 PM in response to lplacenciaby KHAANNN,I'm really glad I came across this issue, I think we're all sharing a similar issue that pre-dates Yosemite, here's why
When I got my macbook brand new (discrete graphics / mid 2014 model, 1 month ago), it had some issues initially, it almost halted to a stop during setup, which is not unseen, yet uncommon, wish I re-installed things then, I've seen other people mentioning mavericks/lion issues, so I think we all had the cause at that time
Now after upgrading to Yosemite, the issue is still around, for me it manifests itself as erratic dock behaviour, dock moves to the second monitor sometimes, multi-touch gestures stop working etc.

Nov 24, 2014 7:11 AM in response to KHAANNNby Christian Arild Strømmen,Just starting having this issue with a new riMac yesterday, and not the computer is completely unusable.
I can VNC in and access the desktop, and it thinks it's connected to a 18" monitor for some reason. Repaired file permissions with disk utility, but the screen is still not detected properly. Restarted the computer, but the permissions on displaypolicyd are messed up again. I see the file vault login screen, and the progress indicator screen, but once it's time to show the desktop the screen goes blank.
Tried resetting the PRAM as well, but that didn't help.
What do I do?

On the macrumors thread someone reported the issue also happens at clean installs

Nov 25, 2014 3:33 AM in response to KHAANNNby Christian Arild Strømmen,Well I got it back up and running here now without it happening.
Interestingly I just realized exactly when the problem started happening. It was when after I tried to change the resolution for the first time (to a scaled one). -

Dec 14, 2014 1:10 AM in response to sky13netby Christian Arild Strømmen,Oh man, I had AirServer installed as well. That might also have been my problem.

Dec 24, 2014 7:23 AM in response to dr_clickby SmithersJr,I have this same problem: can't log back in after sleep and displaypolicyd errors when repairing permissions.
My work-around is to uninstall DropBox. I still see the displaypolicyd permission errors when checking; but, I can now log in every time. That's a pain for me because I have some applications that require DropBox for syncing. :-/

Dec 24, 2014 8:37 AM in response to SmithersJrby larisa pedroncell,make sure you have the latest dropbox. they released it a few months after the yosemite release to deal with yosemite related issues. so far it has worked like a charm.

Dec 24, 2014 8:48 AM in response to larisa pedroncellby SmithersJr,I updated Dropbox to 3.0.3 a few weeks ago. It seemed to help for a bit; but, it didn't last. I see 3.0.4 is out now, so I'll give that a try.

Dec 25, 2014 9:05 AM in response to SmithersJrby SmithersJr,Nope, Dropbox 3.0.4 is doing the same thing. :-(
Goodbye, Dropbox. :-/

Dec 28, 2014 4:31 AM in response to lplacenciaby kraen,I have the same problem on a MBP early 2011. First thought it was the graphics card issue others have encountered but I can log into the computer via Safe Mode without problems. But when I log into the computer as usual it crashes after a certain amount of time.
It's not totally clear in my case if the repair permissions trick is doing the job but I will continue trying.
I'm on 10.10.1 and Dropbox has been uninstalled. Issue still present.
