Using PrimaryGPU allows to use the NVIDIA driver by default instead of the iGPU. This is also required in order to use external display when internally connected from the NVIDIA hardware. Unfortunately, setting this option automatically when an external display is connected is not supported by NVIDIA at this time. To recover this previous behaviour, you can use:
$ cp -p /usr/share/X11/xorg.conf.d/nvidia.conf /etc/X11/xorg.conf.d/nvidia.conf
And edit the file to use:
Option "PrimaryGPU" "yes"
/!\ SSDM and lightdm display manager users: Please Have a look at the ArchLinux wiki about configuring display manager. In Fedora, Gnome users don't need this change.
For GLX + OpenGL, the environment variable NV_PRIME_RENDER_OFFLOAD_PROVIDER provides finer-grained control. While NV_PRIME_RENDER_OFFLOAD=1 tells GLX to use the first NVIDIA GPU screen, NV_PRIME_RENDER_OFFLOAD_PROVIDER can use an RandR provider name to pick a specific NVIDIA GPU screen, using the NVIDIA GPU screen names reported by xrandr --listproviders.
Examples:
__NV_PRIME_RENDER_OFFLOAD=1 __GLX_VENDOR_LIBRARY_NAME=nvidia glxgears
__NV_PRIME_RENDER_OFFLOAD_PROVIDER=NVIDIA-G0 __GLX_VENDOR_LIBRARY_NAME=nvidia glxgears
The NV_PRIME_RENDER_OFFLOAD environment variable causes the special Vulkan layer VK_LAYER_NV_optimus to be loaded. Vulkan applications use the Vulkan API to enumerate the GPUs in the system and select which GPU to use; most Vulkan applications will use the first GPU reported by Vulkan. The VK_LAYER_NV_optimus layer causes the GPUs to be sorted such that the NVIDIA GPUs are enumerated first. For finer-grained control, the VK_LAYER_NV_optimus layer looks at the VK_LAYER_NV_optimus environment variable. The value NVIDIA_only causes VK_LAYER_NV_optimus to only report NVIDIA GPUs to the Vulkan application. The value non_NVIDIA_only causes VK_LAYER_NV_optimus to only report non-NVIDIA GPUs to the Vulkan application.
Examples:
__NV_PRIME_RENDER_OFFLOAD=1 __VK_LAYER_NV_optimus=NVIDIA_only vkcube
To configure a graphics application to be offloaded to the NVIDIA GPU screen, set the environment variable NV_PRIME_RENDER_OFFLOAD to 1. If the graphics application uses Vulkan, that should be all that is needed. If the graphics application uses GLX, then also set the environment variable GLX_VENDOR_LIBRARY_NAME to nvidia, so that GLVND loads the NVIDIA GLX driver. NVIDIA's EGL implementation does not yet support PRIME render offload.
Examples:
__NV_PRIME_RENDER_OFFLOAD=1 vkcube
__NV_PRIME_RENDER_OFFLOAD=1 __GLX_VENDOR_LIBRARY_NAME=nvidia glxinfo | grep vendor __NV_PRIME_RENDER_OFFLOAD=1 __GLX_VENDOR_LIBRARY_NAME=nvidia ./osu.AppImage

My Fix:
Just launch in Terminal
$ google-chrome-stable
Suggested Solutions:
type in address bar
chrome://flags/#enable-webrtc-pipewire-capturer
WebRTC PipeWire support > Enable
Note: Weirdly, this doesn't happen with Chromium and Firefox
Add this parameter to enable PipeWireCapture in wayland session
$ ./Deskreen-1.0.12.AppImage --enable-features=WebRTCPipeWireCapturer
Problem: Mutter Link: https://gitlab.gnome.org/GNOME/mutter/-/issues/2216
Temporary Solution:
- Keeps redraging into the area, will work about 10-20% of the time
- Switch to Xorg
https://forum.manjaro.org/t/disable-gnome-screenshot-sound/13513/2
PATH: /usr/share/sounds/freedesktop/stereo

This is related to the GPU sanbox I think

OpenGL games may also need dlsym hooking. Add --dlsym or MANGOHUD_DLSYM=1 env var to your command like mangohud --dlsym %command% for Steam.
Change the download location
$ flatpak run --command=gsettings com.github.unrud.VideoDownloader set com.github.unrud.VideoDownloader download-folder '/mnt/LinuxData/Download'
$ ffmpeg -i input_filename.WebM output_filename.MP4
If there's error related to "can't be divided by 2", use crop function so the width and height is divisible by 2.
$ ffmpeg -i input_filename.webm -vf "crop=trunc(iw/2)*2:trunc(ih/2)*2" output_filename.MP4

I found a fix today after looking for weeks. Hopefully it works for you as well.
- Disable all Controller Support Options (IE PS4 Support etc)
- Exit Steam and unplug the controller
- Open the config.vdf file stored on your computer
- By default it is located in
C:\Program Files (x86)\Steam\config\config.vdf - Search for "SDL_GamepadBind" and delete everything underneath it
- Save the file
- Start Steam and plug in the controller
Change the Git Config in the system
$ git config --global init.defaultBranch main

- Setup the KVM
- Enable shared memory
- Add FileSystem shared
- Setup on the Windows Guest
- Install WinFsp
- Download virtiofs ISO (https://github.com/virtio-win/virtio-win-pkg-scripts/blob/master/README.md)
- Open ISO, and copy virtiofs folder
- Run virtio-win-guest-tools.exe
- Starting the virtiofs service (Run as Admin) so the disk will be mounted starting with Z:\

In the HyperX case, there are five different handlers available (can be more/less in others):
handler for keyboard events, standard mode mouse handler (e.g. remote USB keyboard witch touchpad). I'm assuming it is always there by design just by referring to its name "System Control", it provides events for power, sleep, etc. referring to "Consumer Control", it provides events for multimedia and related special keys handler for NKRO events I can find the "standard mode" keyboard handler easily by looking for EV=120013 (I'm not sure if it is a proper way either). In that particular case I could look for other entries with an identical bitmap of supported keys, but unfortunately in Havit case that bitmap is pretty different. Another pattern that I see and might be useful is to look for sysrq in handlers, However, I don't know what it means.
And that's it.
How can I properly find both standard mode and NKRO handlers for given keyboard?

Using the default settings, the sleep is triggerred when reaching 2% of battery level, which is very low. This usually make the device switch off because of lost power before the sleep proses even finished.
On my laptop, this lead to power lost, resetting UEFI to default, and power on immediately when receiving power.
$ nano /etc/UPower/UPower.conf

A new chromium build (Snap) is made by collaboration between Canonical and Intel to get video acceleration working (Encoding and Decoding)
To try this version, you will need to switch Chromium to the hwacc branch.
To install hardware accelerated Chromium: snap install chromium --channel=latest/candidate/hwacc
To switch from a previous installation: snap refresh chromium --channel=latest/candidate/hwacc
To go back to the stable channel: snap refresh chromium --channel=latest/stable
