Dell XPS 13 9350 – External Display
UPDATE: 2/24/2017 – Haven’t tried for awhile with external monitor, but did recently and no luck in 16.10. Updated to 17.04, still no dice (everything else works fine though, so that’s nice). Hopefully this will get fixed. 🙁
UPDATE: 6/1/2016 – To stop the flickering in chrome run chrome non-maximized. Fixes it. ‘Fix’ is in the google chrome bug report on this issue. Hopefully they fix for maximized too, but good enough for now.
UPDATE: 4/30/2016 – With 16.04 released my results have been solid. I’ve had issues where if plugging in the USBC cable didn’t work I could unplug POWER from the laptop and then retry and it would work … but I haven’t had much of that anymore either. It seems this ‘use case’ is stabilizing and mostly reliable. I do see screen flickering at times especially when flash/html5 video is playing through chrome, but I noticed that on my System76 Galago UltraPro as well so I’m guessing this has to do with an X driver issue and nothing specific to the XPS 13. Looks like this laptop is only getting better with age.
If you’ve followed my Dell XPS 13 9350 installation guide and have the 4.4-rc7 kernel running, you know that most things are running pretty well for me.
One thing that the new XPS 13 has (which is very cool) is USB-C. The downside is that there’s no displayport, and no other ways to get video out.
I took a chance and bought this USB-C to DisplayPort adapter from amazon and hoped for the best. Lo and behold, opened it up, plugged it in (side note: make sure you push it in until it ‘clicks’) and bam … my Dell UltraSharp U2715H poppped up like a champ and worked right away – note this is at 2560×1440 resolution.
I love ubuntu and this laptop!
