I had the latest DisplayLink driver and it still did the same thing to me. And it gets worse than that. No errors are generated but the speed is so slow it is almost unbearable whenever the DisplayLink device is in use. I could click the icon for Files to launch Nautilus from the Unity favorites bar, and it would not appear for almost two whole minutes! Disconnect the device and reboot, and all was fine with the world-- except that it wasn't. I could not use my third monitor to do editing work.
Unfortunately, it became easier just to remove Ubuntu from my system and move to another distribution that does work with DisplayLink devices. There were serious problems with power saving, too. Suspend would crash the machine rather than suspend to memory, and this was on a system that I purchased because it was certified for Ubuntu! In Fedora, the distribution I now am using exclusively, I still see flickering when the mouse is moved to the top of the screen but the flickering is bearable compared to the ungodly slowness on the screen with that flickering, in Ubuntu 16.04.2. I do not know what the problem is on Ubuntu with DisplayLink devices but it was too unbearable, and that is unfortunate because I really liked working in Ubuntu, with Unity being my chosen interface. But I hear that even Unity will be going away. I hope that one day the display bugs involving DisplayLink displays will be fixed. Until then, if I want to get work done, and not have to spend time waiting between mouse clicks and app launches, I have to go elsewhere for at least the time being. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1278223 Title: Mouse Flickering after adding 3rd Monitor To manage notifications about this bug go to: https://bugs.launchpad.net/xorg-server/+bug/1278223/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
