Description Piotr Kołaczkowski 2016-04-05 08:51:25 UTC

I have a Dell M4600 laptop with an external display attached to display port.
DP is wired to nvidia chip in this laptop.

With optimus disabled in bios setup, both displays work fine using Nvidia chip and the external screen can be marked as primary and behaves as primary.
Unfortunately in this mode, 2D performance is quite bad, to the point it is hardly usable. I guess this is due to power management problems that I know are being worked on, but please confirm yo know about it and I don't need to file a separate bug for this.

After enabling optimus in bios, both displays work fine using Intel chip, the DP connection is detected properly and nvidia chip powers up to enable DP. 2D performance is smooth and usable. However, setting the external display as primary is not possible with xrandr:
