nvidia-prime can't switch

  • 772

I have a dual boot system with Ubuntu 18.10 and Windows 10, which have GTX 1050 Mobile and Intel HD Graphics 630.

I installed nvidia-390 driver from a ppa but I can't use my NVidia card even if prime-select returns nvidia:

$> prime-select query
   nvidia
$> sudo lshw -c video | grep configuration
   configuration: driver=nvidia latency=0
   configuration: driver=i915 latency=0

nvidia smi shows 410 (I tried before):

smi output

lspci -vnn | grep VGA -A 12

lcpi output

in

Settings > Details > About

it shows only Intel:

Intel only

In NVIDIA X Server Settings there are just two options for switching, there is no other tabs like temperature, etc.

I am using CS:GO on Steam for benchmarking and i can get 15-20 fps, while I can get 120 fps in Windows 10.

drivers nvidia graphics nvidia-optimus 18.10
