Talk:Dell XPS 15
I believe the entire multihead section is far more complex than necessary for a 9350 model XPS 15 w/ hidpi display. HDMI, DP->DVI, and the internal monitor all "just work" at the same time with a mundane arandr configuration (nvidia card off, intel only)
Since I've not tested plain display port, nor DP->VGA yet, want to see if anyone has wildly different experiences with that model before I do any edits?
I agree with Thomasam. I have the newer 9550 model (Skylake) and both, the HDMI as well as using a USB 3.1 Type C/Tunderbolt 3 to HDMI adapter just work (all at the same time and perfectly fine if plugged/unplugged at runtime). I even don't have any X11 configs. Just make sure you apply all the recent BIOS and Thunderbolt firmware updates and use a HDMI cable that is known to work (I had a rather frustrating few days with a brand new but broken cable which sent me down many misleading rabbit holes including this wiki page).
Issues with sound (9550 Skylake ALC3266)
I wrote the section regarding sound. I will attempt to clean it up and conform it to the guidelines.
Issues with suspend/resume/flickering (9550 Skylake)
I submitted a bug report to Dell about the A10 BIOS update that breaks suspend/resume. (reference #934603967) I also mentioned about the screen flickering issue in the report. I will keep this talk updated when I receive a response back from Dell.
EDIT: Here is a gist of the response. Regular corpo Dell zombie response...
I will test it in BIOS to see if the flickering persists (which, I believe, still does)
We cannot point towards a faulty cable/LCD because EVERYONE is experiencing the same issues. Unless if they just shipped out faulty LCD/GPU/LVDS components?
Future additions/changes I will be applying:
- BIOS updates issues/caveats - i3wm base config file (due to 4k screen, looking to save other people some time and get a base config available)
