Can Sözbir's questions

My problem is with snapd. When I connect my pc to my mobile hotspot, my pc downloads lots of data. I downloaded nethogs and I saw usr/lib/snapd/snapd downloads sometimes with mb/s. I thought this could be resolved with an update, but the "Software Updater" application doesn't help. I tried to disable "automatically check for updates" in 'Software & Updates' but that doesn't help either. I found sudo systemctl stop snapd.service command and after running it, /usr/lib/snapd/snapd is missing from nethogs (not downloading anything) but after ~1-2 min, it starts downloading again.

How can I stop that download?

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):

lspci -vnn | grep VGA -A 12

in

Settings > Details > About

it shows only Intel:

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.
