+
+Especially when using continuos-length Brother label printers it can be useful to set up custom
+formats.
+After setting up the CUPS install the package that provides
+`brpapertoollpr_<printer name in cups>` which differs from printer to printer.
+For example when using a Brother QL-600 this command is named `brpapertoollpr_ql600` and on some
+[Linux](/wiki/linux.md) distributions like [Arch Linux](/wiki/linux/arch-linux.md) is provided in a
+package called `brother-ql600`.
+
+To then set up a new custom format run the following command.
+
+```sh 
+brpapertoollpr_<printer name in command> -P <printer name in cups> -n <format name> -w <width> -h <height>
+```
+
+`<printer name in command>` is the part of the command that corresponds to the printer as described
+in the previous sentence.
+`<printer name in cups>` and `<format name>` are the name of the printer already set up and given in
+CUPS and the name chosen for the new format.
+And `<width>` and `<height>` are width and height of the new format both given in millimeters.
+A complete command could look something like the following. 
+
+
+```sh 
+brpapertoollpr_ql600 -P Brother_QL-600 -n "62mmx12mm" -w 62 -h 12
+```
+
+The command to delete a custom format is the following.
+It uses the same variables and names as the command above.
+
+```sh 
+brpapertoollpr_ql600 -P <printer name> -d <format name>
+```
+
+The usage of this command could look similar to the following example.
+
+```sh 
+brpapertoollpr_ql600 -P Brother_QL-600 -d "62mmx12mm"
+```
+
+After setting up the new format it can be selected in the CUPS interface and used with the Brother
+printer it was set up for.

+
+### Convert Handwriting to Vector Graphic
+
+This section is based on a two source.
+One is a [YouTube video by vecteezy](https://www.youtube.com/watch?v=gW19K11ihIc) which explains the
+setting of the levels, aswell as the tracing of the bitmap.
+though an older version was used which is why some features may be found at another place in the
+menus.
+This was changed accordingly for the following guide.
+The other is a [YouTube video by Logos By Nick](https://www.youtube.com/watch?v=EFHLF1hcrjg) which
+explains the simplification process.
+
+To convert handwriting to a vector graphic an image of the writing should first be opened in
+Inkscape.
+First the levels of black and white can be changed by using `Extensions > Raster > Levels` and
+changing the values for white and black points.
+Afterwards the bitmap should be traced.
+For this select `Path > Trace Bitmap` and change the values in the Detection mode
+`Brightness cutoff` until it matches your expectations.
+After this the image has been converted to a bitmap, but most of the times it is not smooth and has
+quite some errors.
+The removal can be done by hand by removing the points manually.
+This is useful to do for bigger errors.
+For smaller errors `Path > Simplify` can be used.

+# GTK
+
+[GTK](https://gtk.org) is an GUI and widget toolkit.
+
+## Setup
+
+On most linux distributions different GTK versions are installed as a dependency of various
+programs that use graphical user interfaces.
+
+### Configurations
+
+GTK has different versions.
+For GTK3 and GTK4 configurations can be achieved by creating the file `settings.ini` in the folders
+`~/.config/gtk-3.0` and `~/.config/gtk-4.0`.
+An example file that enables dark mode, uses the Adwaita theme and sets the default font to
+sans-serif of size 12 looks something like the following.
+
+```txt 
+[Settings]
+gtk-application-prefer-dark-theme = true
+gtk-icon-theme-name = Adwaita
+gtk-font-name = Sans 12
+```
+
+For GTK2 an older version of config files has to be used.
+The file can be found or created at `~/.config/gtk-2.0/gtkrc-2.0`.
+A similar setup to the previous configuration of GTK3 and GTK4 can be achieved by the following.
+
+```txt 
+gtk-theme-name="AdwaitaDark"
+gtk-font-name="Sans 12"
+```
+
+#### Achieving a System-Wide Uniform Look
+
+[Qt](/wiki/linux/qt.md) is the other big widget toolkit in use.
+An easy way to achieve a uniform look of GTK and Qt is the usage of the Adwaita theme in both
+toolkits.
+This is also described in the
+[official Arch wiki](https://wiki.archlinux.org/title/Uniform_look_for_Qt_and_GTK_applications#Styles_for_both_Qt_and_GTK).
+
+Since it is the default theme on GTK it just has to be set inside as described in the 
+[configuration section](#configuration).
+
+For setting the same theme for Qt refer to the
+[corresponding entry](/wiki/linux/qt.md#achieving-a-system-wide-uniform-look).

+This section will also discuss various other greeters like the
+[LightDM-Mini-Greeter](#lightdm-mini-greeter).
+
+This setup needs an `xsession`.
+An alternative to this is using `xinitrc` as an `xsession`.
+The process of this is desribed in the
+[display manager entry](/wiki/linux/display_managers.md#use-xinitrc-as-xsession).
+Make sure to have a working `xsession` or `xinitrc`.
+If you are not sure about it, use the tests provided in the penultimate step.
+
+Then edit the config file `~/.dmrc` and edit the file to the following contents.
+
+```txt 
+[Desktop]
+Session=xinitrc
+```
+
+Before finishing the setup the functionality should be tested.
+This can be done by using one or both of the following commands. 
+
+```sh 
+lightdm --test-mode --debug
+systemctl start lightdm.service
+```
+
+Finally the [SystemD](/wiki/linux/systemd.md) lightdm service needs to be enabled and reboot the
+system.

+```
+
+## Greeters
+
+LightDM features the option to choose between many different greeters.
+This section focusses on various greeters.
+
+The greeter can be set with the option `greeter-session` under the section `[Seat:*]` in the file 
+`/etc/lightdm/lightdm.conf`.
+This will look similar to the following line.
+
+```txt 
+[Seat:*]
+
+greeter-session=lightdm-mini-greeter
+```
+
+If no `greeter-session` is set the default will fall back to the
+[LightDM-GTK-Greeter](#lightdm-gtk-greeter).
+
+### LightDM-GTK-Greeter
+
+The [LightDM-GTK-Greeter](https://github.com/Xubuntu/lightdm-gtk-greeter) is the default greeter 
+for LightDM.
+This is the default [greeter](#greeters) of [GTK](/wiki/linux/gtk.md) but others may be chosen.
+
+### LightDM-Mini-Greeter
+
+[LightDM-Mini-Greeter](https://github.com/prikhi/lightdm-mini-greeter) is a minimal, single-user
+greeter.
+
+For the LightDM-Mini-Greeter to work correctly some settings have to be set in the file
+`/etc/lightdm/lightdm-mini-greeter.conf`.
+The following lines show an example of this file.
+The most important changes have been done to set the `user` under `[greeter]` 
+and `background-image` under `[greeter-theme]`.
+The background image path can vary, but lightdm has to be able to access the

 # 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.
+
+## Kernel Versions
+
+There are a few possible kernel version that can be used by `mkinitcpio`.
+
+### 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.
 
 ## 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).

+### 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.
+

+COMPRESSION_OPTIONS=(-v -5 --long)

+
+#### Achieving a System-Wide Uniform Look
+
+[GTK](/wiki/linux/gtk.md) is the other big widget toolkit in use.
+An easy way to achieve a uniform look of GTK and Qt is the usage of the Adwaita theme in both
+toolkits.
+This is also described in the 
+[official Arch wiki](https://wiki.archlinux.org/title/Uniform_look_for_Qt_and_GTK_applications#Styles_for_both_Qt_and_GTK).
+
+A simple way to achieve this in Qt is the installation of
+[adwaita-qt6](https://github.com/FedoraQt/adwaita-qt) which is also available as an
+[AUR](/wiki/linux/package_manager.md#installing-an-aur-program-with-a-specific-version) package.
+After the installation it can be selected by `qt6ct` as described in the
+[configuration section](#configuration).
+
+For setting the same theme for GTK refer to the
+[corresponding entry](/wiki/linux/gtk.md#achieving-a-system-wide-uniform-look).
+
+## Troubleshooting 
+
+This section will focus on errors and the fixing of errors of Qt.
+
+### Incorrect Configuration: `The libqt6ct.so plugin is compiled against incompatible Qt version`
+
+When updating the system it is possible that the theme will not work correctly anymore.
+Often the error `The libqt6ct.so plugin is compiled against incompatible Qt version` is responsible
+for this.
+To fix it most of the time it is enough to recompile the `qt6ct` package.
+Afterwards a reboot might be needed for the theme to be displayed correctly again.

+### Replacing All Occurences in a Directory
+
+To all occurences of a given string for all files recursively in a given directory run the
+following command, where `<directory>` is the directory to replace in.
+`<query>` is the string to replace and `<replacement>` is the string it should replaced with; both
+of these may be escaped if special signs are contained in them.
+
+```sh
+find <directory> -type f -exec sed -i "s/<query>/<replacement>/g" {} \;

+
+### Using ANSI Color
+
+ANSI-Colors can easily be used in the shell by using the control sequences as described by
+[techstop](https://techstop.github.io/bash-script-colors).
+Each color has an own sequence and can be combined to affect the background.
+Additionally the font can also be changed using these control sequences.
+
+The following tables display these sequences.
