Created attachment 894956 [details] log of main graphics this issue may not reflect on this log. It was first noticed yesterday when I tried to use a projector. The same lockup happens when switching to mirror display or changing the resolution of the projector. Since the dicrete card manages the projector port, Xorg.1.log and Xorg.2.log will show more activity.
