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). 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.
