Tomasz Raganowicz, the DisplayLink driver you are using is outdated (latest is 1.3.54).
Despite this, the article you linked doesn't point to Launchpad at all. Likely, because this report hasn't been fully root caused, and folks simply add "Me too!" comments that aren't helpful for a developer to solve the problem. Also, given the details in your comment are impossible to use to fix the issue you have, it will help immensely if you use the computer the problem is reproducible with, file a new report with Ubuntu by first ensuring the package xdiagnose is installed, click the Yes button for attaching additional debugging information after running the following from a terminal: ubuntu-bug xorg Also, please feel free to subscribe me to it. -- 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
