** Description changed: - 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. The pointer doesn't flicker on third - monitor (DisplayLink monitor). + I have a three screen setup, the built-in laptop screen, a monitor + connected directly into the laptop via DisplayPort, and a monitor + connected via a USB DisplayLink Adapter. - This also seems to be related to this bug: - https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1485682 + What happens is that when a monitor is connected via the USB DisplayLink + Adapter, the mouse icon flickers only on the laptop screen and monitor + connected via DisplayPort (not on the monitor connected via USB + DisplayLink Adapter). + + However, this is also reproducible if I either deactivate the built-in + laptop screen, or disconnect the DisplayPort connected monitor. + + WORKAROUND: Disconnect the USB DisplayLink Adapter for the computer.
