If the second monitor is also connected via Startech USB32HD4K, mouse cursor flickers frequently and can even disappear on the PRIMARY monitor (the one that is connected to Nvidia GTX 960). On the second monitor, everything is fine. - One interesting thing I noticed is that if I set rotation in "All - Settings"->"Screen Display" to "Clockwise", "Anti-clockwise" or "180 - degrees" (just not "Normal") on the PRIMARY monitor, this issue is - mitigated. + WORKAROUND: In the GUI go to All Settings > Screen Display > for the primary monitor change Rotation from Normal to any of the following: + Clockwise + Anti-clockwise + 180 degrees ProblemType: Bug DistroRelease: Ubuntu 16.04 Package: xorg 1:7.7+13ubuntu3 ProcVersionSignature: Ubuntu 4.10.0-38.42~16.04.1-generic 4.10.17 Uname: Linux 4.10.0-38-generic x86_64 .tmp.unity_support_test.0: - + ApportVersion: 2.20.1-0ubuntu2.10 Architecture: amd64 CompizPlugins: No value set for `/apps/compiz-1/general/screen0/options/active_plugins' CompositorRunning: compiz CompositorUnredirectDriverBlacklist: '(nouveau|Intel).*Mesa 8.0' CompositorUnredirectFSW: true Date: Tue Nov 14 23:59:01 2017 DistUpgraded: Fresh install DistroCodename: xenial DistroVariant: ubuntu DkmsStatus: evdi, 1.4.210, 4.10.0-38-generic, x86_64: installed ExtraDebuggingInterest: Yes GraphicsCard: - NVIDIA Corporation Device [10de:1406] (rev a1) (prog-if 00 [VGA controller]) - Subsystem: Dell Device [1028:072b] + NVIDIA Corporation Device [10de:1406] (rev a1) (prog-if 00 [VGA controller]) + Subsystem: Dell Device [1028:072b] InstallationDate: Installed on 2017-11-14 (0 days ago) InstallationMedia: Ubuntu 16.04.2 LTS "Xenial Xerus" - Release amd64 (20170215.2) Lsusb: - Bus 002 Device 002: ID 17e9:4301 DisplayLink - Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub - Bus 001 Device 003: ID 8087:0a2b Intel Corp. - Bus 001 Device 002: ID 046d:c534 Logitech, Inc.
