XPS 13 9350 - monitor output via USB type C under linux

Hello Friends. 

I got myself a 9350 about a week ago, and I promptly installed Xubuntu 15.10. WiFi did not work, so I replaced it with the Intel 7265, so WiFi is now running great. I also tried to get the D1000 dock to work, but ran into issues with the DisplayLink driver, so I instead got a USB-C to DP adapter from Google (they supposedly have a similar solution for their chromebook). However, that did not work (does not show up in xrandx) for example, and I am not sure where to start digging. 

My question is then if anyone have successfully used an adapter for USB-C to DisplayPort/HDMI that works with 4k monitors and Linux, or is there anything special that needs to be installed?

I assume that just waiting will eventually solve it, but the XPS 13 is such a nice machine that I really want to start using it as my main work computer. The only thing I know that does not work is the suspend (that I can live without until it gets fixed in future kernel upgrades) and the monitor output, so I am eager to find a solution.

Thanks in advance, 

Staffan

And by "waiting" I did not mean that gnomes will somehow magically implement support for it. I am well aware and appreciative of the hard work that the Sputnik group, Linux kernel and X developers put into this. Just wanted to make that clear. (And also bump my question ;)

I have a 2014 XPS 13 that is working great with Ubuntu 15.10 and the Dell D3100 USB monitor dock. Please see my previous posts for details

This is kinda off-topic, but how well is the battery life on xps 13 9350 with linux?

not good. 6h might be a realistic figure for some light workload.

I find it really good (guess it depends on perspective). For me it lasts 7 or 8 hours. My monitor is usually about at half brightness. I do mostly light work combined with a multi-core compile every hour that lasts about 10 minutes.

Note that I had to let my laptop run out of battery a few times to teach it that it can last longer. It was saying "critical" with 5 minutes. Instead of plugging in, it lasted another 20 minutes and later learned that it can do so. I dont know if this is good though, but it is a non-standard shutdown when it runs out by itself.

I just flew from east to west coast this week, reading an e-book. After about 5 hours of reading a PDF in Okular at minimum screen brightness (with wifi on accidentally) the battery monitor turned red and warned only 50 min left. Turns out there are no electric plugs on this plane, so I disabled the wifi and the remaining time shot up to over 1.5 hours remaining.  By landing time it still estimated about 1 hour of remaining battery.

So, on minimum screen brightness with a light workload, I would guess 7 hours.

Thanks Cloojure - 

I did eventually get my 9350 to play nice with the D1000 that I bought, but it required me to manually override the resolution as reported by xrandr. By default, the only high resolution reportedly supported by the D1000 and my Asus 4k monitor was 3840x2160, however I never got that to work right (it was zoomed in and confusing). When I added 2560x1440 (I can provide details if anyone is interested), I did get it to work "right". I remain annoyed with the low update rate (mouse movements are a bit choppy), as well as the occasional errors that xubuntu reports (usually when setting things up, and never seem to have too much of an effect on anything), but at least it is working. My coworker have the 9343 with the D3100 running windows, and that adapter did work properly with 3840x2160. My suspicion is that the D1000 have the same display link chip, but software limited poorly to only support 2560x1440. So, I will probably get a D3100 for my multi-line programming needs and give the D1000 to yet another coworker.

Hopefully the USB-type C thunderbolt 2 docking station Dell TB15 in 2016 will have linux support from day 1?

Staffan

I have not ran it on battery for long enough to have any idea just yet. It is a good question though.

Hi all, 

to add something to this thread. 

Got the XPS 13 (9350) three weeks ago, running Mint 17.3, kernel 3.19.0-32 w/o any problems (replaced the wifi-card before installing).

Monitor output via a cheap Aukey USB-C to HDMI-Adapter worked fine.

Got the WD15 Dell Dock (130W) today and struggling to get it working. Hot-Plugging the Dock causes the system to freeze, booting with the dock plugged in causes the boot to stop. 

Apparently, Staffan's hopes did not come true. Is anyone from the Dell Sputnik Team reading this thread an able to shed some light? I will see if a kernel update fixes the problem.

Best

Claus
