Good news: Hardly any error messages "*ERROR*" too many retries..." (etc.). Bad News: Absolutely no connection made to my external monitor over the Apple DP connector. Hardware: I'm using a Lenova Think Pad S430, which uses "Intel® Ivybridge Mobile" graphics. I'm trying to connect an external monitor via an Apple DP to VGA connector (so, not exactly the same hardware discussed above, but very similar symptoms - if the difference means this is the wrong ticket, sorry, please instruct as to where I should post this). My "real" use-case is a little different - I need to connect to the projectors at work. By the way, I have a work-around that works most of the time - downgrade to the 3.6.11 kernel - the last kernel that came with a "normal" Arch Linux upgrade which works. After that came the 3.7 and 3.8 kernels, and none of those have worked with my hardware. Here's what I did: I connected the Apple connector. I'll attach the Xorg.0.log next.</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> </ul> </body> </html>
