I've tried, but the proprietary nvidia driver can't enable the second GPU if the first (the integrated Intel) is already working, so I'm left with only one monitor and this glitch disappear (as it disappers if I disable the intel GPU and use only the nvidia one with the nouveou driver).
This glitch only happen if they are both enabled, in a dual gpu configuration. Xorg is autodetecting all the configuration automatically. -- 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/1551022 Title: mouse pointer leaves trail Status in xorg package in Ubuntu: Incomplete Bug description: In my desktop system Kubuntu 15.10 I have the integrated graphic card (Intel HD3000) and a discrete graphic card (Nvidia GTX 550). 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. --- ApportVersion: 2.20-0ubuntu3 Architecture: amd64 BootLog: CompizPlugins: No value set for `/apps/compiz-1/general/screen0/options/active_plugins' CompositorRunning: None DistUpgraded: 2016-02-24 01:06:09,804 DEBUG enabling apt cron job DistroCodename: xenial DistroRelease: Ubuntu 16.04 DistroVariant: ubuntu GraphicsCard: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller [8086:0122] (rev 09) (prog-if 00 [VGA controller]) Subsystem: ASUSTeK Computer Inc. 2nd Generation Core Processor Family Integrated Graphics Controller [1043:844d] NVIDIA Corporation GF116 [GeForce GTX 550 Ti] [10de:1244] (rev a1) (prog-if 00 [VGA controller]) Subsystem: ZOTAC International (MCO) Ltd.
