== System Won’t Reboot After the Shutdown Process Completes ==
Check the Intel Watchdog isn't blacklisted, some performance guides will tell you to disable it for speed, breaking reboots.
sudo grep -iR "blacklist iTCO_wdt" /etc/modprobe.d/

If you see any output like below proceed, if the command returns with no output, it's not this causing the problem.
/etc/modprobe.d/blacklist.conf:blacklist iTCO_wdt
Edit the file containing the line
nano /etc/modprobe.d/blacklist.conf
And comment out the line, restart one more time and it should be fixed.
#blacklist iTCO_wdt

'''Proton-GE will install the vc2019 runtime for you, making this manual fix obsolete, only do the following if you can't use Proton-GE.'''

Take the file ucrtbase.dll from a Windows install at C:/Windows/System32/ '''AND''' C:/Windows/SysWOW64 then place them in the folders for Steams Proton (case sensitive) :

/home/user/.steam/steam/steamapps/compatdata/976730/pfx/drive_c/windows/system32

== Kill program from command line ==

Show all processes
ps aufx
Or search for a specific process name
ps aufx | grep firefox
Example output
user 7243 27.4 2.1 17807108 1413692 ? Ssl 21:32 18:31 | \_ /home/user/Desktop/firefox/firefox-bin
The second column is the process ID.

Some applications, pretty much any that use flatpak and any browser, will have multiple processes in a "tree" (see below), in these cases you may need to kill every process in the tree ("kill 3136 3607 3634") for things to fix themselves.

user 3136 0.0 0.0 3432 2292 ? Ss 21:31 0:00 '''| \_''' bwrap --args 84 -- easyeffects
user 3607 0.0 0.0 3440 1728 ? S 21:31 0:00 '''| | \_''' bwrap --args 84 -- easyeffects
user 3634 9.0 0.3 1619592 249548 ? SLl 21:31 6:26 '''| | \_''' easyeffects

Gentle process kill (try this first), the app will be asked to exit nicely.
kill 7243
Still won't close? Hard Kill, data may be lost that wasn't saved to disk yet.
kill -9 7243
If all processes have the same name you can use "killall"
killall firefox-bin

== Memory Tweaks ==

Keep more data in RAM instead of swapping to disk, make the system more responsive, especially if your swap (paging file in Windows terminology) file/partition is on a hard disk drive.
vm.swappiness=1

== Network ==

Enable BBR (https://en.wikipedia.org/wiki/TCP_congestion_control#TCP_BBR) Greater top speeds and more reliable, especially for higher latency connections like 3/4/5G and satellite.
net.core.default_qdisc = cake
net.ipv4.tcp_congestion_control = bbr
Allow more packets to be queued up before the system drops them, pretty much required for Gigabit+ connections
net.core.netdev_max_backlog=16384
Allow more connections to be queued on the system, good for programs that establish a lot of connections, such as P2P applications.
net.core.somaxconn=8192

NVreg_InitializeSystemMemoryAllocations=1 \
NVreg_RegistryDwords=RMIntrLockingMode=1 \

== Don’t Allow GPU to Stay at Maximum Power While Running Tasks ==

This will allow the graphics card to run at lower speeds while doing things that use CUDA, such as video decoding
sudo [[nano]] /etc/environment
Add
CUDA_DISABLE_PERF_BOOST=1

== X11 Tweaks ==
sudo [[nano]] /etc/X11/xorg.conf.d/01-nvidia.conf
Add

Section "ServerFlags"
# Only applicable if you're using older Xlibre (<25.0.0.16), safe to remove otherwise
Option "IgnoreABI" "true"
# Increase the max clients allowed, this helps prevent your system being unable to launch apps
Option "MaxClients" "2048"
# Will improve performance when it's fully supported.
Option "Debug" "dmabuf_capable"
EndSection

== (WW) NVIDIA: Failed to bind sideband socket to ==
Only occurs if running rootless X11
sudo [[nano]] /etc/X11/xorg.conf.d/01-nvidia.conf
Add
Section "Device"
Identifier "Device0"
Driver "nvidia"
VendorName "NVIDIA Corporation"
Option "SidebandSocketPath" "/var/run/nvidia-xdriver/"
EndSection
We also need to set up a method for making the folder with the correct permissions every boot.
sudo [[nano]] /etc/tmpfiles.d/nvidia-sideband.conf
Insert this line to make the folder.
d /run/nvidia-xdriver 0770 root users
Add your user to the users group, you may already be in the group but this ensures it.
usermod -a -G users <your username here>
Reboot the system.
