If the Windows driver is also affected, it may be bad hardware. (Or just close to the edge of specification!) The flicker itself may be underruns. If you can grab a video, that would help immensely. If it is an underrun, they should also be reported into a drm.debug=6 dmesg. If you disable i915.ko entirely and the problem still persists, then we can say definitely the hardware is very suspect - but we may be able to workaround the problem...</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> <li>You are on the CC list for the bug.</li> <li>You are the assignee for the bug.</li> </ul> </body> </html>
