Thanks. I did that. My monitor now gives me a blank screen for half a second every so often (Using 4.1-rc1 with your patches and the intel_psr merge). I'm going to run it this way for awhile and see how long that happens. Have you made any other changes to the graphics? (sna vs uxa, etc) I heard you're using an XPS 13. Are you using the QHD or the FHD version? Wonder where the difference is.
