Title:
[DisplayLink] screen flicker on gnome with t450s with ultra dock
Status in evdi package in Ubuntu:
New
Bug description:
picture on monitor connected to DisplayPort flickers occasionally. between 1
and 20 times per hour.
searched for similar bugs or problems, related to docking station. Does not
happen when using laptop standalone / connect screen manually.
DisplayLink Driver is installed/compiled from official website.
whenever the flickering happens, this appears in log:
"libinput error: client bug: timer event20 debounce short: scheduled
expiry is in the past (-10ms), your system is too slow"
anything I can contribute? fix?
I tried to get daily builds of intel-driver but that broke wayland/gdm so I
rolled back.
only link I could find that seems relevant is
https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1572667 - which
expired.
thanks
Andreas
