The viewing of temperatures of coolers aswell as the selection of RGB-settings can be achieved by
using [liquidctl](https://github.com/liquidctl/liquidctl).
## Temperature
To check the temperature the command `sensors` can be used which (on most distributions) is a part
of the `lm_sensors` package.
It will then display all the available temperature sensors available aswell as many other sensors
like the RPM for fans.

# Kernel
The [Linux](/wiki/linux.md) kernel is an open-source Unix-like computer operating system kernel.
## Versions
There are a few possible kernel version.
### Stable-Version: `linux`
The stable version of the [Linux](/wiki/linux.md) kernel can usually be found in a package called
`linux` and is usually installed from the start or in the recommended setup.
### Zen-Version: `linux-zen`
The zen kernel is a collaborative project of kernel hackers to provide the best
[Linux](/wiki/linux.md) kernel for everyday systems.
Especially the response time of the system under load
[is said to be better](https://github.com/zen-kernel/zen-kernel/wiki/Detailed-Feature-List#zen-kernel-improvements).
This will - for example - make the system less stuttery when something is compiled.
Desktop and gaming systems will benefit the most.
To setup the zen kernel do the following. Firstly install the packages `linux-zen` and
`linux-zen-header`.
Afterwards open the file `boot/loader/entries/arch.conf` and change the following lines.
```txt
linux /vmlinuz-linux
initrd /initramfs-linux.img
```
To look like the following lines.
```txt
linux /vmlinuz-linux-zen
initrd /initramfs-linux-zen.img
```
If you want to switch the backup to Zen too, the backup file in `boot/loader/entries/` has to be
changed too.
Afterwards the system should be rebooted for the change to take effect.

# mkinitcpio
`mkinitcpio` is a script to create an initial ramdisk environment.
This environment provides the [Linux](/wiki/linux.md) kernel, containing essential drivers and
utilities required at boot.

## Usage
The following addresses various usage and configuration choices for mkinitcpio.
### Default and Fallback Images
It is recommended to have at least one default and one fallback version for kernels.
After the initial generation of the kernel the configuration file can be found in the
`/etc/mkinitcpio.d` directory.
For the [`linux`-kernel](#stable-version-linux) it would contain `linux.preset` and for the
[`linux-zen`-kernel](#zen-version-linux-zen) `linux-zen.preset`.
Inside these preset files the following line manages the generation of a default or fallback image.
```txt
PRESETS=('default' 'fallback')
```
Notice that the options are separated only by a space.
To just build a fallback image remove `'default'` or vice versa.
Afterwards the initial ramdisk has to be [rebuild](#manually-generate-initial-ramdisk).
### Manually Generate Initial Ramdisk

```
### Enable/Disable Compression
To save space on the boot partition the kernel images can be compressed.
To enable compression activate it in `/etc/mkinitcpio.conf` under `COMPRESSION=`.
In the configuration file some compression algorithms are recommended.
Additionally compression options can be set under `COMPRESSION_OPTIONS=`.
An easily usable example for this is the following line.
```txt
COMPRESSION_OPTIONS=(-v -5 --long)
```
To disable compression remove the corresponding lines.
After enabling and disabling of the compression the initial ramdisk has to be
[rebuild](#manually-generate-initial-ramdisk).

### `No space left on device`
If this error or one similar to this is shown the boot partition is filled up completely during the
generation of the initial ramdisk.
This can be fixed by either [compressing the image](#enabledisable-compression) or by
[disabling unused fallbacks](#default-and-fallback-images).

This section addresses various usages of the arch linux package managers.
#### Downgrading Packages
#### Ignoring Packages
Packages can be ignored by adding the package in `/etc/pacman.conf` under `IgnorePkg`.
In the following example `waybar` is ignored from updates.
To add more packages just add them separated by spaces.
```txt
IgnorePkg = waybar
```
To unignore the package from updates remove it from this line.
#### Downgrading Packages
Packages of the AUR can be downgraded by using the
[Downgrade](https://github.com/archlinux-downgrade/downgrade) program.
This program can then easily be used to an AUR package.
This works like the following assuming the package `v4l2loopback-dmks` needs to be downgraded.
```sh
```sh
sudo downgrade v4l2loopback-dmks
```
Afterwards the target version can be selected and the downgrading process will conclude.
After the downgrade of a package you will get asked if you want to
[ignore future updates](#ignoring-packages).

If an error shows up that describes that a file of a package `exists in filesystem` usually a
permission/owner error happened.
This can happen when running `pacman -Syyu`.
To update the package either way the following command can be used.
`<package name>` should be exchanged for the package that throws the error.
