nvidia - Windows "repeat" on moving them - Ask Ubuntu


with second monitor connected via displayport, have issue windows repeat on primary monitor (lenovo thinkpad t460p).

screenshot

when click on desktop after dragging window, drawings dissappear.

my system:

  • os: ubuntu 16.10 64 bit
  • cpu: intel® core™ i7-6820hq cpu @ 2.70ghz × 8
  • graphics card: geforce 940mx/pcie/sse2

is known issue?

i fixed installing recommended nvidia driver:

sudo add-apt-repository ppa:graphics-drivers/ppa sudo apt-get update

check recommended drivers: ubuntu-drivers devices

== cpu-microcode.py == driver   : intel-microcode - distro non-free  == /sys/devices/pci0000:00/0000:00:01.2/0000:02:00.0 == model    : gm108m [geforce 940mx] modalias : pci:v000010ded0000134dsv000017aasd00005050bc03sc02i00 vendor   : nvidia corporation driver   : xserver-xorg-video-nouveau - distro free builtin driver   : nvidia-370 - third-party free recommended driver   : nvidia-367 - distro non-free driver   : nvidia-364 - third-party free

in case nvidia-370 - third-party free recommended. i've installed it:

sudo apt-get install nvidia-370 nvidia-prime reboot
