Introduction
This is a simple guide on how to enable intel-nvidia hybrid graphics on a laptop. So that certain applications run on a discrete chip and others on an embedded one. To my surprise, on the Internet, I did not find a simple instruction on how to run certain applications using discrete graphics. So I'll write as simply as I see fit.
I have a KDE Neon 5.21 system - by and large - Ubuntu LTS with a KDE Plasma 5.21 desktop environment, a GeForce MX150 video chip
1. Install the driver
a) If you have a system on Qt (As a rule, the KDE or LXQt environment), then using this command through the terminal, load the program for installing the drivers:
sudo apt install software-properties-qt
If you have a system on GTK then using this command:
sudo apt install software-properties-gtk
Although there is no fundamental difference
b) Then run it as root
sudo software-properties-qt
You can also add a shortcut to launch in the application menu
Instructions for KDE
In the folder, ~/.local/share/applications/
create a file software properties qt.desktop
with the following content
[Desktop Entry]
Categories=System;Settings;
Comment[ru_RU]=drivers
Comment=drivers
Exec=konsole -e "~/.local/share/applications/software-properties-qt.sh"
GenericName[ru_RU]= \s
GenericName= \s
Icon=systemsettings
MimeType=
Name[ru_RU]=software properties qt\n
Name=software properties qt\n
Path=
StartupNotify=true
Terminal=false
TerminalOptions=
Type=Application
X-DBUS-ServiceName=
X-DBUS-StartupType=
X-KDE-SubstituteUID=false
X-KDE-Username=
And a file software properties qt.sh
in the same folder:
#! /bin/bash
echo software-properties-qt
sudo /usr/bin/software-properties-qt
After reboot, the shortcut will appear in the menu
But this is far from necessary, it is quite enough to launch the hybrid graphics settings from the console for our purposes.
c) Go to the last tab Additional drivers
and install the required driver. I chose the most recent version, which is not tested
and is notserver
d) After installation, restart the device
2. Configuring the video card
a) :
sudo apt install nvidia-settings
b) PRIME Profiles
:

NVIDIA On-Demand

Vulkan :

. , program . :

Conclusion
This method, as I understand it, works exactly for programs using the OpenGL and Vulkan libraries. Unfortunately, I didn't manage to run a Windows application through Wine that uses DirectX, but that's a completely different story. (OpenGL applications work under Wine)
