Some days ago I attached a monitor on the iGPU and enabled it, giving me a triple head system (two monitors on the Nvidia and one on the Intel). From that moment, the mouse pointer started to leave a trail when it pass over something that is animating. I'm using nouveau for the nvidia card. I tried to upgrade to Kubuntu 16.04, but it gives me the same glitch. It's not possible to take a screenshot because it will repaint the desktop prior to take it, so the glitch doesn't appear: I had to take a photo. 1) $ lsb_release -rd Description: Ubuntu Xenial Xerus (development branch) Release: 16.04 2) $ apt-cache policy xorg xorg: Installato: 1:7.7+13ubuntu1 Candidato: 1:7.7+13ubuntu1 Tabella versione: *** 1:7.7+13ubuntu1 500 500 http://de.archive.ubuntu.com/ubuntu xenial/main amd64 Packages 100 /var/lib/dpkg/status 3) I expect normal mouse behaviour 4) Mouse leaves a trail of pointers ProblemType: Bug DistroRelease: Ubuntu 16.04 Package: xserver-xorg-core 2:1.17.3-2ubuntu4 ProcVersionSignature: Ubuntu 4.4.0-8.23-generic 4.4.2 Uname: Linux 4.4.0-8-generic x86_64 ApportVersion: 2.20-0ubuntu3 Architecture: amd64 Date: Sun Feb 28 22:50:01 2016 ExecutablePath: /usr/lib/xorg/Xorg InstallationDate: Installed on 2015-11-19 (100 days ago) InstallationMedia: Kubuntu 15.10 "Wily Werewolf" - Release amd64 (20151021) SourcePackage: xorg-server UpgradeStatus: Upgraded to xenial on 2016-02-24 (4 days ago) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1551022/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : desktop-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
