Problems with Fedora 28 Suspend on Dell XPS 15

asked 2018-05-14 20:01:57 -0500

Let me start by saying I have had this problem for a while. I have had this same problem with Fedora 27 as well. I thought 28 might be the release to resolve it. But alas, no luck.

The problem is that when I suspend my laptop, the display will not turn on when I attempt to bring it back. This can happen either through Lock -> Suspend. Or by shutting the screen for a sufficient period of time. There is a similar question that remains unanswered here: https://ask.fedoraproject.org/en/ques...

I believe my keyboard and mouse/trackpad are both still functional when I open the laptop, I would guess it is only the display that is not working. I do see the backlight on the keyboard.

My questions are:

  1. What is going on?
  2. How can I troubleshoot this?
  3. What steps can I take to fix it?

Apologies for the poor set of information, I am not a hardware person so I don't really know the distinction between noise and relevant information. Any guidance is appreciated.
