Thread: Screen flickering on DELL XPS-13-7390

  1. #1

    Default Screen flickering on DELL XPS-13-7390

    I just purchased a brand new DELL XPS13-7390 laptop and installed Tumbleweed on it. Unfortunately the screen flickers like crazy. If windows runs on the same laptop the screen works very well. Also if I connect an external screen to it everything works fine. What is the reason of this flickering? Did anybody have the same problem?

    Probably this:
    https://bugzilla.opensuse.org/show_bug.cgi?id=1159305

    Various places have suggested fixes or workarounds, such as:
    https://www.pcsuggest.com/fix-linux-.../#comment-8444
    or that it's a recurring problem for some Intel users but not others (e.g. none of mine):

    Possibly similar or related (and recent):

    I installed opensuse 15.1 on the laptop and it worked without screen flickering. But after I run the online update it started to flicker again. I suspect that there are some changes in the newer kernel versions. Does anybody know why it does work with kernel 4.12.14-lp151.27-default and it doesn't work with a newer kernel?

    Please provide output using code tags the output from the following run in an Xterm or Konsole:
    Code:
    inxi -SGxxza
    You may need to install the inxi information gathering script first.

    I updated inxi to version: 3.0.38-00 (2020-03-14). With this version the -a parameter worked. Below you can fin the output of

    I don't believe any of the regulars here have Comet Lake experience or hardware. Your best bet may be to ask about this on the intel-gfx mailing list or irc channel. There may be a cmdline option that they know about that would fix or work around this, or a patched kernel or driver to try.

    I asked on the intel-gfx mailing list, but I got no response. Does anyone have another option?

    I see you did get a response several hours ago, a request for information that had not already been provided in this thread. https://lists.freedesktop.org/archiv...ch/233756.html

    It looks like the problem has been solved in 5.6 kernels

    https://gitlab.freedesktop.org/drm/i...72#note_432762

    When will kernel 5.6 be released for tumbleweed?
