TAKEN FROM: https://gist.github.com/lbrame/1678c00213c2bd069c0a59f8733e0ee6
This is a collection of the tweaks and modification I've made to my Arch Linux installation over the months. These may be applicable to other distros, but please check first before doing anything. I also included Arch Wiki references for all the procedures I mentioned. My recommendation is not to blindly follow this gist but to always check with the Arch Linux wiki first. Things move fast and by the time you're reading this my gist may be out of date. Lastly, the golden rule: never execute a command you don't understand.
Yay!
I use yay as my AUR helper. You can install it from the AUR:
git clone https://aur.archlinux.org/yay.git
cd yay
makepkg -csi
Fonts!
Installing missing fonts
DEs often don't include common fonts that some programs require. See KB/Linux/Desktop/ArchLinux/Fonts.
Enabling ClearType rendering
Microsoft no longer holds their patents on the ClearType font rendering and it has been merged to upstream freetype2.
Create the file ~/.config/fontconfig/conf.d/20-no-embedded.conf and make it look like the following:
<?xml version="1.0"?>
<!DOCTYPE fontconfig SYSTEM "fonts.dtd">
<fontconfig>
<match target="font">
<edit name="embeddedbitmap" mode="assign">
<bool>false</bool>
</edit>
</match>
</fontconfig>
Finally, log in again. This is an user setting and it will be reverted if you ever delete this file and it won't work on other users.
Installing Windows fonts
I finally added Microsoft fonts as they're handy to keep around and tend to be necessary to display web pages and Office documents correctly.
To install them system wide, copy the C:\Windows\Fonts folder from a Windows installation to /usr/share/fonts:
mkdir /usr/share/fonts/WindowsFonts
cp /windows/Windows/Fonts/* /usr/share/fonts/WindowsFonts/
chmod 644 /usr/share/fonts/WindowsFonts/*
These commands assume your Windows partition is mounted at /windows as they've been copied verbatim from the Arch Wiki. If you don't dual boot or don't mount your Windows partition to /windows, just replace /windows/Windows/Fonts/* with wherever location you copied that folder to.
Improving I/O performance
Using the BFQ scheduler
Arch Wiki reference: https://wiki.archlinux.org/index.php/Improving_performance#Changing_I/O_scheduler
Linux notoriously gets very slow with I/O intensive operations such as moving a lot of files at once and swapping. If you have a spinning hard drive or a not-so-fast SSD, the BFQ scheduler can help improve system responsiveness during I/O intensive operations. I still use a SATA SSD for lack of a faster connector on my laptop and I have perceived significantly better overall performance by using the BFQ I/O scheduler. If your boot disk is a fast NVme SSD it's generally not the best idea to use the bfq scheduler for it, but since the I/O scheduler is set per-disk, it might be a good idea to use it for any spinning hard disk permanently connected to the computer (e.g. a secondary disk to store games and movies).
To set the BFQ scheduler, you need to specify some udev rules to tell Linux what scheduler to use on what kind of disks. For example, you could use the mq-deadline scheduler on your NVme drives and the bfq scheduler on your SSDs. I decided to set my rules in such a way that no scheduler is used for NVme SSDs, but bfq is used for everything else. To do this, create the file /etc/udev/rules.d/60-ioschedulers.rules and fill it in as below:
# set scheduler for NVMe
ACTION=="add|change", KERNEL=="nvme[0-9]*", ATTR{queue/scheduler}="none"
# set scheduler for SSD and eMMC
ACTION=="add|change", KERNEL=="sd[a-z]|mmcblk[0-9]*", ATTR{queue/rotational}=="0", ATTR{queue/scheduler}="bfq"
# set scheduler for rotating disks
ACTION=="add|change", KERNEL=="sd[a-z]", ATTR{queue/rotational}=="1", ATTR{queue/scheduler}="bfq"
Reboot and you're done.

Improving laptop battery life with TLP and powertop
Arch Wiki reference: https://wiki.archlinux.org/index.php/TLP https://wiki.archlinux.org/index.php/Powertop
Linux distros tend to deplete laptops' batteries quite quickly, which can be detrimental to some. tlp is a set-and-forget, auto-tuning option for laptops that I have found to work very well (albeit it comes with drawbacks, such as a perceived decrease in performance). Setting it up on Arch Linux is pretty straightforward:
pacman -S tlp
systemctl enable tlp.service --now
powertop is a powerful commandline program to keep track of battery consumption. It also allows the user to quickly alter some system settings that have an impact on battery life. You can use it to make a quick tuning:
powertop --auto-tune
However, don't enable powertop's service if you already use TLP.
Systemd configuration
Also see KB/Linux/Server/systemd.

Taming the journal's size
Systemd's system journal's size can go out of control. There are some things you can do to keep it in control:
journalctl --vacuum-size=100M
journalctl --vacuum-time=2weeks
Forwarding the journal to /dev/tty12
This is very simple. Just create the file /etc/systemd/journald.conf.d/fw-tty12.conf and fill it like this:
[Journal]
ForwardToConsole=yes
TTYPath=/dev/tty12
MaxLevelConsole=info
Then, restart the service:
systemctl restart systemd-journald.service

Using the modesetting driver
Arch Wiki reference: https://wiki.archlinux.org/index.php/Kernel_mode_setting#Early_KMS_start
Enabling Early KMS
Arch Wiki reference: https://wiki.archlinux.org/index.php/Kernel_mode_setting#Early_KMS_start https://wiki.archlinux.org/index.php/Mkinitcpio#Image_creation_and_activation
I decided to start kernel modesetting during the initramfs stage. To do this, you can just add the i915 or amdgpu module to /etc/mkinitcpio.conf like this:
MODULES=(i915)
# or
MODULES=(amdgpu)
And then
mkinitcpio -p linux
Finally, reboot.
