Hannes Bochmann, thank you for reporting this and helping make Ubuntu better.
As per http://support.lenovo.com/us/en/products/laptops-and- netbooks/thinkpad-l-series-laptops/thinkpad-l450 an update to your computer's buggy and outdated BIOS is available (1.16). If you update to this following https://help.ubuntu.com/community/BIOSUpdate does it address the issue? If it doesn't, could you please both specify what happened, and provide the output of the following terminal command: sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date For more on BIOS updates and linux, please see https://help.ubuntu.com/community/ReportingBugs#Bug_reporting_etiquette . Please note your current BIOS is already in the Bug Description, so posting this on the old BIOS would not be helpful. Also, you don't have to create a new bug report. Once the BIOS is updated, if the problem is still reproducible, and the information above is provided, then please mark this report Status Confirmed. Otherwise, please mark this as Invalid. Thank you for your understanding. ** Tags added: bios-outdated-1.16 ** Changed in: xorg (Ubuntu) Importance: Undecided => Low ** Changed in: xorg (Ubuntu) Status: New => Incomplete -- 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/1511244 Title: Mouse pointer flickers at using DisplayLink Status in xorg package in Ubuntu: Incomplete Bug description: Using the new official DisplayLink driver for Ubuntu from http://www.displaylink.com/downloads/ubuntu.php for my USB- DisplayLink-Adapter causes on the two main monitors (DisplayPort and internal monitor) a flickering mouse.
