While I'm sure the degraded resolution is very annoying, it's surely more desirable than a black screen. Needs further analysis of the link training failure. Side note, you seem to be missing the DMC firmware, available from the linux-firmware repository. Probably unrelated to the problem at hand, but, well, you never know.</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>
