Stephan Fabel, thank you for reporting this and helping make Ubuntu better.
To clarify: 1) What is the full manufacturer and model of the DisplayLink adapter? 2) Did this issue occur with a prior version of the DisplayLink driver? 3) Did this issue start to occur after a Ubuntu package update? 4) Does this issue occur if you connect the monitor to the laptop without using the DisplayLink adapter? 5) To see if this is already resolved in Ubuntu, could you please test http://cdimage.ubuntu.com/daily-live/current/ and advise to the results? ** Changed in: xorg (Ubuntu) Importance: Undecided => Medium ** Changed in: xorg (Ubuntu) Status: New => Incomplete ** Tags added: latest-bios-2.2.1 -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1724307 Title: Mouse cursor flickers when using external DisplayLink monitor Status in xorg package in Ubuntu: Incomplete Bug description: This may be a duplicate of https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1278223. In order to provide more information, there was a request to open another bug and attach the relevant info to it. OS: Ubuntu 16.04 x64 Kernel: 4.10.0-37-generic X.Org X Server: 1:7.7+13ubuntu3 (v1.19.3) Monitor 1: 1920 x 1080 - Laptop's Native Monitor Monitor 2: 1920 x 1080 - DisplayLink (USB) connected AOC E2775SJ Monitor Using DisplayLink driver v1.4 (latest as of today), the mouse screen flickers on refresh both on the external as well as on the native monitor, and it seems worse on the laptop's monitor than on the external one, going as far as vanishing for several minutes (pointer still being active as I can see icons being highlighted, etc. but no mouse pointer being drawn). Usage of Google Chrome seems to aggravate the issue, although it's not gone otherwise.
