BOOT_IMAGE=/boot/vmlinuz-4.9.0-994-generic root=... ro i915.enable_rc6=0 quiet splash It works 24 hours for now (was suspended at night) and I haven't seen any flickering nor glitches so far. Previously the graphics was garbage (flickering, glitches, sometimes black screen at boot, weird things after connecting/disconnecting external screen), and now it feels stable. Also there is nothing negative about Intel DRM in dmesg! :) I recommend installing Intel DRM Nightly kernel for anyone who's still experiencing such symptoms. I'm curious if there's more Skylake cards that are fixed with latest commits.</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>
