With PSR enabled (/sys/module/i915/parameters/enable_psr == 1) and drm-intel-nightly from 28th of September I cannot reproduce this. I am *not* using the xserver-xorg-video-intel driver, my setup is using the xorg modesetting driver. That's the only difference I can think of (except that I'm not using the except same laptop model, obviously). I've tested setting the external display as a secondary display, and as a mirror, both worked as they should. Before testing I ran powertop --auto-tune (to ensure that nothing blocks power management).</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> <li>You are the assignee for the bug.</li> <li>You are on the CC list for the bug.</li> </ul> </body> </html>
