I've acquired a new ergonomic mouse (this one) and it behaves strangely.When I begin moving the mouse, Xorg's CPU usage skyrockets, resulting in occasionally choppy mouse movement.Futher, it shows up twice in the xinput listing.I am running Xubuntu on an IBM ThinkPad P50.$ uname -Linux  4.8.0-52-generic #55~16.04.1-Ubuntu SMP Fri Apr 28 14:36:29 UTC 2017 x86_64 x86_64 x86_64 GNU/LinuxNotice here that my ergonomic keyboard also shows up as a pointer  not sure if this is part of the issue (PixArt Gaming Mouse is the offender):$ xinput list Virtual core pointer                      id=2    [master pointer  (3)]    Virtual core XTEST pointer                    id=4    [slave  pointer  (2)]    SynPS/2 Synaptics TouchPad                    id=16   [slave  pointer  (2)]    PixArt Gaming Mouse                           id=12   [slave  pointer  (2)]    TPPS/2 IBM TrackPoint                         id=17   [slave  pointer  (2)]    PixArt Gaming Mouse                           id=13   [slave  pointer  (2)]    KINESIS FREESTYLE KB800 KB800 Kinesis Freestyle       id=11   [slave  pointer  (2)] Virtual core keyboard                     id=3    [master keyboard (2)]     Virtual core XTEST keyboard                   id=5    [slave  keyboard (3)]     Power Button                                  id=6    [slave  keyboard (3)]     Video Bus                                     id=7    [slave  keyboard (3)]     Video Bus                                     id=8    [slave  keyboard (3)]     Sleep Button                                  id=9    [slave  keyboard (3)]     KINESIS FREESTYLE KB800 KB800 Kinesis Freestyle       id=10   [slave  keyboard (3)]     Integrated Camera                             id=14   [slave  keyboard (3)]     AT Translated Set 2 keyboard                  id=15   [slave  keyboard (3)]     ThinkPad Extra Buttons                        id=18   [slave  keyboard (3)]I am running Xorg (obviously):$ aptitude show xorgPackage: xorgState: installedAutomatically installed: noVersion: 1:7.7+13ubuntu3My hardware:$ lspci00:00.0 Host bridge: Intel Corporation Sky Lake Host Bridge/DRAM Registers (rev 07)00:01.0 PCI bridge: Intel Corporation Sky Lake PCIe Controller (x16) (rev 07)00:02.0 VGA compatible controller: Intel Corporation Skylake Integrated Graphics (rev 06)00:14.0 USB controller: Intel Corporation Sunrise Point-H USB 3.0 xHCI Controller (rev 31)00:14.2 Signal processing controller: Intel Corporation Sunrise Point-H Thermal subsystem (rev 31)00:16.0 Communication controller: Intel Corporation Sunrise Point-H CSME HECI #1 (rev 31)00:16.3 Serial controller: Intel Corporation Sunrise Point-H KT Redirection (rev 31)00:17.0 SATA controller: Intel Corporation Sunrise Point-H SATA controller [AHCI mode] (rev 31)00:1c.0 PCI bridge: Intel Corporation Sunrise Point-H PCI Express Root Port #1 (rev f1)00:1c.2 PCI bridge: Intel Corporation Sunrise Point-H PCI Express Root Port #3 (rev f1)00:1c.4 PCI bridge: Intel Corporation Sunrise Point-H PCI Express Root Port #5 (rev f1)00:1d.0 PCI bridge: Intel Corporation Sunrise Point-H PCI Express Root Port #13 (rev f1)00:1f.0 ISA bridge: Intel Corporation Sunrise Point-H LPC Controller (rev 31)00:1f.2 Memory controller: Intel Corporation Sunrise Point-H PMC (rev 31)00:1f.3 Audio device: Intel Corporation Sunrise Point-H HD Audio (rev 31)00:1f.4 SMBus: Intel Corporation Sunrise Point-H SMBus (rev 31)00:1f.6 Ethernet controller: Intel Corporation Ethernet Connection (2) I219-LM (rev 31)01:00.0 VGA compatible controller: NVIDIA Corporation GM107GLM [Quadro M1000M] (rev a2)04:00.0 Network controller: Intel Corporation Wireless 8260 (rev 3a)3e:00.0 Unassigned class [ff00]: Realtek Semiconductor Co., Ltd.

Xorg at 99% CPU when moving pointer in circles; pointer device shows up twice
