[Desktop-packages] [Bug 1827790] Re: Dell XPS 13 9380 - Screen flashes
Does the problem occur in only Xorg sessions ("Ubuntu") or Wayland too
("Ubuntu on Wayland")?

Title:
Dell XPS 13 9380 - Screen brightness flashes
Status in mutter package in Ubuntu:
Incomplete
Status in xorg-server package in Ubuntu:
Incomplete
Bug description:
Hello,
I have a new 2019 Dell XPS 13 (9380). I ordered the official Ubuntu
edition from Dell which came with 18.04, but I've since wiped it and
installed 19.04 from a fresh ISO download. This is the non-touch non-
4K version (13-inch 1080p).
Every so often (maybe a couple of times per minute), the screen
flashes brighter, as if the brightness has been turned up momentarily
and then back down again.
I previously had an issue with the brightness / colours changing
slightly when I opened menus or if the screen content changed
slightly, but I fixed that by disabling Dynamic Brightness in the
BIOS. It is definitely a better experience with that turned off.
However the screen flashing still persists.
I booted a live image of Fedora 30 now that it has been released, and
so far I have not seen the screen flashing, so I do not think the
hardware is faulty.
I ran apport-bug, so hopefully the collected information has been
attached.
Thank you.

On the basis of 3 of us deeming that the symptoms of the other bug are different to the ones described in this bug, I have removed the duplicate link. I hope that's OK. If it helps narrow it down, it seems that we all have the non-touch 1080p version, and all notice it much more when Night Light is enabled. ** This bug is no longer a duplicate of bug 1826125 Dell XPS 13 9380 flickering (Whiskey Lake) -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1827790 Title: Dell XPS 13 9380 - Screen flashes Status in xorg package in Ubuntu: Confirmed Bug description: Hello, I have a new 2019 Dell XPS 13 (9380).

*** This bug is a duplicate of bug 1826125 *** https://bugs.launchpad.net/bugs/1826125 I have some doubt that this is a duplicate of bug 1826125, though I see how they are similar. I'm experiencing the same issue described in this bug, and the visual effect is quite different than the photos and videos attached to the other bug. In the other one, the issue appears to involve different parts of the display flickering around, or different parts of the screen getting "out of sync" so it looks like there are horizontal bands. The problem in the other bug is also described as quite frequent/constant. I'm not experiencing any of that, but I am experiencing what Daniel C describes in this bug: my entire screen flashes quite brightly for a split second, then calms back down. The effect is uniform across the screen, there's no banding or shifting that I can see. It only happens once every few minutes, not constantly as described in the other bug. The flashing is most noticeable when the "Night Light" effect is active in the evening, though I believe I've also seen it happen during the day. One other important distinction: like Daniel C, I have an XPS 9380 with the non-touch 1080p display, and I wiped Dell's pre-installed 18.04 and installed 19.04 instead. The other bug has several references in the comments to it affecting the XPS 9380 with the "4k" display. So I believe the flashing described in this bug is a different problem with a different panel. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1827790 Title: Dell XPS 13 9380 - Screen flashes Status in xorg package in Ubuntu: Confirmed Bug description: Hello, I have a new 2019 Dell XPS 13 (9380).
