 + 
 +<note important>Please note that **Hyperbola is not supporting Vulkan** and only implements the OpenGL-standard. The reasoning is a minimalist approach as Vulkan needs wide more dependencies.</note> 
 +===== Running ===== 
 + 
 +The [[https://man.openbsd.org/OpenBSD-6.5/Xorg.1|Xorg(1)]] command is usually not run directly, instead the X server is started with either a [[en:system:userspace:application:display_managers|display manager]] or xinit. 
 + 
 +==== xinit ==== 
 + 
 +The xinit program allows an user to manually start an Xenocara display server. The [[https://man.openbsd.org/OpenBSD-6.5/startx.1|startx(1)]] script is a front-end for [[https://man.openbsd.org/OpenBSD-6.5/xinit.1|xinit(1)]]. 
 + 
 +<note important>If **Lumina Desktop** is being used you would need to use <color #620BB9/#EEDDFF>start-lumina-desktop</color> instead</note> 
 + 
 +xinit is typically used to start [[en:system:userspace:window_manager|window managers]] or [[en:system:userspace:desktop_enviroment|desktop environments]]. 
 + 
 +=== Installation === 
 + 
 +Install the [[https://www.hyperbola.info/packages/?name=xenocara-xinit|xenocara-xinit]] package. 
 + 
 +<code bash> 
 +# pacman -S xenocara-xinit 
 +</code> 
 + 
 +=== xinitrc === 
 + 
 +~/.xinitrc is handy to run programs depending on X and set environment variables on X server startup. If it is present in a user's home directory, startx and xinit execute it. Otherwise startx will run the default /etc/X11/xinit/xinitrc. 
 + 
 +<note> 
 +Xinit has its own default behaviour instead of executing the file. See [[https://man.openbsd.org/OpenBSD-6.5/xinit.1|xinit(1)]] for details. 
 +</note> 
 + 
 +This default xinitrc will start a basic environment with [[https://www.hyperbola.info/packages/?name=xenocara-twm|xenocara-twm]], [[https://www.hyperbola.info/packages/?name=xenocara-xclock|xenocara-xclock]] and [[https://www.hyperbola.info/packages/?name=xterm|xterm]] (assuming that the necessary packages are installed). 
 + 
 + 
 + 
 +Therefore, to start a different [[en:system:userspace:window_manager|window manager]] or [[en:system:userspace:desktop_enviroment|desktop environment]], first create a copy of the default xinitrc in your home directory: 
 + 
 +<code bash> 
 +$ cp /etc/X11/xinit/xinitrc ~/.xinitrc 
 +</code> 
 + 
 +Then edit the file and replace the default programs with desired commands. Remember that lines following a command using exec would be ignored. For example, to start [[https://www.hyperbola.info/packages/?name=xscreensaver|xscreensaver]] in the background and then start [[en:system:userspace:application:window_managers:openbox|openbox]], use the following: 
 + 
 +<code bash> 
 +$ ~/.xinitrc 
 + 
 +... 
 +xscreensaver & 
 +exec openbox-session 
 +</code> 
 + 
 +=== Usage === 
 + 
 +To run Xorg as a regular user: 
 + 
 +<code bash> 
 +$ startx 
 +</code> 
 + 
 +===== Configuring ===== 
 + 
 +<note>Hyperbola supplies default configuration files in /usr/share/X11/xorg.conf.d/, and no extra configuration is necessary for most setups.</note> 
 + 
 +Xenocara uses a configuration file called xorg.conf and files ending in the suffix .conf for its initial setup: the complete list of the folders where these files are searched can be found in [[https://man.openbsd.org/OpenBSD-6.5/xorg.conf.5|xorg.conf(5)]], together with a detailed explanation of all the available options. 
 + 
 +==== Using .conf files ==== 
 + 
 +The /etc/X11/xorg.conf.d/ directory stores host-specific configuration. You are free to add configuration files there, but they must have a .conf suffix: the files are read in ASCII order, and by convention their names start with XX- (two digits and a hyphen, so that for example 10 is read before 20). These files are parsed by the X server upon startup and are treated like part of the traditional xorg.conf configuration file. Note that on conflicting configuration, the file read last will be processed. For that reason the most generic configuration files should be ordered first by name. The configuration entries in the xorg.conf file are processed at the end. 
 + 
 +==== Using xorg.conf ==== 
 + 
 +Xorg can also be configured via /etc/X11/xorg.conf or /etc/xorg.conf. You can also generate a skeleton for xorg.conf with: 
 + 
 +<code bash> 
 +# Xorg :0 -configure 
 +</code> 
 + 
 +This should create a xorg.conf.new file in /root/ that you can copy over to /etc/X11/xorg.conf. 
 + 
 +<note tip> 
 +If you are already running an X server, use a different display, for example: 
 +<code bash> 
 +# Xorg :2 -configure 
 +</code> 
 +</note> 
 + 
 +===== Input devices ===== 
 + 
 +For input devices the X server defaults to the libinput driver, but [[https://www.hyperbola.info/packages/?name=xorg-input-evdev|xorg-input-evdev]] and related drivers are available as alternative. 
 + 
 +[[https://www.hyperbola.info/packages/?name=eudev|eudev]] will detect hardware and both drivers will act as hotplugging input driver for almost all devices, as defined in the default configuration files 10-quirks.conf and 40-libinput.conf in the /usr/share/X11/xorg.conf.d/ directory. 
 + 
 +After starting X server, the log file will show which driver hotplugged for the individual devices (note the most recent log file name may vary): 
 + 
 +<code bash> 
 +$ grep -e "Using input driver " Xorg.0.log 
 +</code> 
 + 
 +If both do not support a particular device, install the needed driver from the [[https://www.hyperbola.info/groups/x86_64/xenocara-drivers/|xenocara-drivers]] group. The same applies, if you want to use another driver.
