Yes, I could; yes, I did; and yes, it does! My Display-Port Adapter works now! That seems to be the fix we've been looking for! (That was the short version - here some details...) I tried this patch both with the DRM-Intel-Nightly-Branch (3.10.0-rc7) and with the stock arch linux kernel (3.9.9), and the results seemed the same: It works, both with external monitors and with a projector. Plug-and-play: I plug the cable into the adapter, the adapter into the notebook, and within a second or three the external display lights up. Curiosity: The log messages "*ERROR* too many tries, giving up" still appear, although everything is working. Irritation: xrandr, arandr and the Gnome-3-Displays-Settings Interface to xrandr (what is the proper name for that thing?) all consider the external displays to be "unknown" and refuse to offer a resolution larger than 1024x768. Using xrandr I managed to blank out both screens (notebook and external) until I unplugged the adapter - but this is a problem I have hardly begun to look at, and which I may just decide to live with: My main external monitor has an hdmi cable and that works (has worked the whole time) just fine (and 1024x768 is just barely enough for presentations with a projector). So, if you need any more information, log files, whatever, please let me know what you need, but I'm happy - for the time being. Mostly I'm curious now when this patch will make it's way into the stock kernels!</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>
