General

Startup

  • fbsplash (formerly gensplash) is a userspace implementation of a splash screen for Linux systems. It provides a graphical environment during system boot using the Linux framebuffer layer.

X

Xwindows drives the underlying graphical interface of most if not all Unix/Linux computers providing a GUI. It was developed in 1984 at MIT. After around 35 years of development, tweaking and adding of new hardware and ideas, it is generally acknowledged to be a bit of a beast. It should be remembered that the common configuration at time of development was a single mini running X providing individual views to Xterminals in a timesharing system. Nowadays the norm is X providing a single screen on a desktop or laptop.

All of this means that there are many ways of achieving the same thing and many slightly different things that can meet the same purpose. In modern X versions sometimes you can get away with limited or no configuration. In the last few years the boast is that X is self configuring. Certainly the best practice rule of thumb is less configuration is better - that is only configure what is wrong.

XDMCP

X Window System is the display and networking protocol developed by MIT. The X is built with network in mind with the capability to run a (graphical) session on a remote computer. In it, an X Display Manager is used to start a session from a local system or from another computer. The request and the start of the session is handled by the XDMCP, which stands for "X Display Manager Control Protocol" and is a network protocol. It provides a way of running the X-Terminal to run on your PC (or MAC) and it uses the X Server to provide a client/server interface between display hardware (the mouse, keyboard, and video displays) and the desktop environment while also providing both the windowing infrastructure and a standardized application interface (quoted from XFree86 Project home page). The X-Terminal can be displayed with an individual window or multiple windows, based on your X window system's software capabilities and setup.

X server


  • Xnest is both an X client and an X server. Xnest is a client of the real server which manages windows and graphics requests on its behalf. Xnest is a server to its own clients. Xnest manages windows and graphics requests on their behalf. To these clients, Xnest appears to be a conventional server.
  • Xephyr is a kdrive based X Server which targets a window on a host X Server as its framebuffer. Unlike Xnest it supports modern X extensions ( even if host server doesn't ) such as Composite, Damage, randr etc (no GLX support now). It uses SHM Images and shadow framebuffer updates to provide good performance. It also has a visual debugging mode for observing screen updates.

DXPC

X Forwarding

xmove

  • xmove - a computer program that allows the movement of X Window System applications between different displays and the persistence of X applications across X server restarts. It solves a problem in the design of X, where an X client (an X application) is tied to the X server (X display) it was started on for its lifetime. Also, if the X server is shut down, the client application is forced to stop running. xmove lets the client disconnect from its current X server, and connect to a new one, at any time. The transition is completely transparent to the client. xmove works by acting as a proxy between the client and server. It is a "pseudoserver" which stores enough server state so that clients can connect to a new server without being disrupted.

Xpra

  • Xpra - X Persistent Remote Applications, is 'screen for X', and more: it allows you to run X programs, usually on a remote host and direct their display to your local machine. It also allows you to display existing desktop sessions remotely. Xpra is "rootless" or "seamless", and sessions can be accessed over SSH, or password protected and encrypted over plain TCP sockets. Xpra adapts to bandwidth constraints and is fully open-source. [2]

The main problem with ssh -X is all your apps close when your connection drops.


  • Xdummy was originally developed by Karl Runge as a ​script to allow a standard X11 server to be used by non-root users with the dummy video driver

x2x

x2vnc

  • x2vnc - A dual-screen hack. will let you use two screens on two different computers as if they were connected to the same computer. Even if one of the computers runs Windows 95/98/NT and the other one runs X-windows. The program will open a small (one pixel wide) window on the edge of your screen. Moving the pointer into this window will trigger the program to take over your mouse and send mouse movements and keystrokes though the RFB protocol to a VNC server running on another machine. When the pointer is moved back towards the opposite edge on the other screen, the mouse is then released again. The operation itself is almost identical to x2x, but most of the code was actually borrowed from the program vncviewer.

xrdp

  • xrdp - An open source remote desktop protocol(rdp) server. Based on the work of FreeRDP and rdesktop, xrdp uses the remote desktop protocol to present a GUI to the user. The goal of this project is to provide a fully functional Linux terminal server, capable of accepting connections from rdesktop, freerdp, and Microsoft's own terminal server / remote desktop clients. Unlike Windows NT/2000/2003/2008/2012 server, xrdp will not display a Windows desktop but an X window desktop to the user. Xrdp uses Xvnc or X11rdp to manage the X session.


Windows

  • Xming is the leading X Window System Server for Microsoft Windows. It is fully featured, lean, fast, simple to install and because it is standalone native Windows, easily made portable (not needing a machine-specific installation or access to the Windows registry). Xming is totally secure when used with SSH and optionally includes an enhanced PuTTY Link SSH client and a portable PuTTY replacement package.

Xvfb

  • Xvfb
    • https://en.wikipedia.org/wiki/Xvfb - or X virtual framebuffer is a display server implementing the X11 display server protocol. In contrast to other display servers Xvfb performs all graphical operations in memory without showing any screen output. From the point of view of the client, it acts exactly like any other X display server, serving requests and sending events and errors as appropriate. However, no output is shown. This virtual server does not require the computer it is running on to even have a screen or any input device. Only a network layer is necessary. Unlike a real display server, Xvfb does not support modern X11 extensions like compositing, Randr or GLX. Xdummy is a newer alternative which supports these extensions as well as providing the same functionality as Xvfb.

Xvfb is primarily used for testing:


Utils

  • xprop - property displayer for X
  • xwit is an X window interface tool. By default when used with no arguments in an xterm it de-iconifies and raises the window. You can specify a different function to do, such as iconifying the window, and apply it to several windows whose name begins with one of the given strings, or a particular window id given, or the window id found in the environment variable WINDOWID (which is set by xterm for the program it runs), or the window under the mouse cursor.
  • xdotool - lets you simulate keyboard input and mouse activity, move and resize windows, etc. It does this using X11's XTEST extension and other Xlib functions. Additionally, you can search for windows and move, resize, hide, and modify window properties like the title. If your window manager supports it, you can use xdotool to switch desktops, move windows between desktops, and change the number of desktops.


  • xmag - allows you to magnify portions of an X screen. If no explicit region is specified, a square with the pointer in the upper left corner is displayed indicating the area to be enlarged. The area can be dragged out to the desired size by pressing Button 2. Once a region has been selected, a window is popped up showing a blown up version of the region in which each pixel in the source image is represented by a small square of the same color. Pressing Button1 in the enlargement window shows the position and RGB value of the pixel under the pointer until the button is released. Typing Q or ^C in the enlargement window exits the program.


  • xdimmer is a lightweight X11 utility to dim the screen backlight when idle, then brighten it back up when mouse or keyboard activity is detected. This power-saving behavior is common on other operating systems and in bloated X11 frameworks like GNOME.
  • xinput - utility to configure and test X input devices
  • XMacro - package contains two simple, C++ programs (xmacrorec and xmacroplay) for recording and replaying keyboard and mouse events on an X server. This functionality is achieved through the XTest extension.


  • KPie is a simple window manipulation tool, modeled after devil's pie, with a Lua-based configuration file.


  • telak is a program which displays pictures in root window. It can display content of local file, or download image via http. Telak can be configured to refetch picture every n seconds, so it can be used to display image from webcam.
  • Xearth sets the X root window to an image of the Earth, as seen from your favorite vantage point in space, correctly shaded for the current position of the Sun. By default, xearth updates the displayed image every five minutes. The time between updates can be changed using either X resource or a command-line option. Xearth can also be configured to either create and render into its own top-level X window or render directly into PPM or GIF files; see the man page for details.
  • Xplanet was inspired by Xearth, which renders an image of the earth into the X root window. All of the major planets and most satellites can be drawn, similar to the Solar System Simulator. A number of different map projections are also supported, including azimuthal, Lambert, Mercator, Mollweide, orthographic, and rectangular.

Fonts

Some fonts like terminus-font are installed in /usr/share/fonts/local, which is not added to the font path by default. By adding the following lines to ~/.xinitrc, the fonts can be used in X11: 

xset +fp /usr/share/fonts/local
xset fp rehash

Input

  • xcape allows you to use a modifier key as another key when pressed and released on its own. Note that it is slightly slower than pressing the original key, because the pressed event does not occur until the key is released. The default behaviour is to generate the Escape key when Left Control is pressed and released on its own. (If you don't understand why anybody would want this, I'm guessing that Vim is not your favourite text editor ;)

ICCCM

  • http://en.wikipedia.org/wiki/Inter-Client_Communication_Conventions_Manual - ICCCM or I39L short for "I", 39 letters and "L")[1] is a standard for interoperability between X Window System clients of the same X server. It is primarily used for communication between normal clients and the window manager. X deliberately specifies "mechanism, not policy". As such, an additional specification beyond the X protocol itself was needed for client interoperation. The ICCCM specifies cut and paste buffers, window manager interaction, session management, how to manipulate shared resources and how to manage device colours. These low-level functions are generally implemented within widget toolkits or desktop environments, meaning that application programmers rarely work directly with the ICCCM itself but instead use the higher-level toolkit functions that implement it.

EWMH

  • ewmhstatus - Outputs the current EWMH desktop name and window title
  • wmctrl is a UNIX/Linux command line tool to interact with an EWMH/NetWM compatible X Window Manager.

Compton

  • Compton - "I was frustrated by the low amount of standalone lightweight compositors. Compton was forked from Dana Jansens' fork of xcompmgr and refactored. I fixed whatever bug I found, and added features I wanted. Things seem stable, but don't quote me on it. I will most likely be actively working on this until I get the features I want. This is also a learning experience for me. That is, I'm partially doing this out of a desire to learn Xlib."

Colours

The color format in awesome is either a standard X color name (blue, darkblue, lightred, etc) or a hexadecimal formatted color (#rrggbb or #rrggbbaa). By using the hexadecimal format, you can also specify an alpha channel: that means that #00ff00 will draw pure green, but #00ff00aa will set the alpha channel to ‘aa’ and will blend the green with the color under it.

Text format

You can use Pango markup in a text string. This allows formating the text rendered inside widgets. Pango markup documentation can be found in the Pango documentation at http://library.gnome.org/devel/pango/stable/PangoMarkupFormat.html.

subtle

2007

  • subtle is a manual tiling window manager with a rather uncommon approach of tiling: Instead of relying on predefined layouts, subtle divides the screen into a grid with customizeable slots (called gravities). For better understanding, the default config uses a 3x3 grid and maps each gravity to one key of the numpad. With those keys, windows can be moved directly to the desired gravity - the same can be done with tagging rules in the config. Another unique concept is the strict tagging: Unlike other tiling window managers, subtle doesn't allow weak tagging and always maps windows to virtual desktops (called views) with matching tags, regardless of the current active view.

TinyTiler is currently under 650 lines of code. In contrast to other tilers, TinyTiler does not have modes nor does have window rules. TinyTiler has only two layouts: right stack and bottom stack. These choices were by design. TinyTiler instead provides two screen sections, the master and the stack. In TinyTiler only one stack window is visibile at a time, the others have tabs in the statusbar.

  • Ayr is a Bash script which lets you manage menus of application launchers, which can be either executables or desktop files. It also opens files and URIs with launchers, desktop files, or applications associated by name or MIME-type. Launchers can be grouped and/or made read-only with tags, and the menu of launchers can be ordered in various ways, including the frequency or recency of launcher usage. Desktop files and MIME-type file associations are detected according to the XDG Base Directory Specification and Association between MIME types and applications standards, as far as is practical, and a wrapper is provided to let ayr function as an xdg-open replacement. Great for integrating with minimal desktop environments and file managers. Ayr uses dmenu to manage its menus. Once installed, execute the command 'ayr -h' for much more information.

When running, use the 'Super' key (also known as the 'Windows' key) to switch between windows and workspaces. This key is usually found between the Ctrl and Alt keys on the keyboard.
  • Rofi - A popup window switcher roughly based on superswitcher, requiring only xlib and pango. This version started off as a clone of simpleswitcher, the version from Sean Pringle. All credit for this great tool should go to him. Rofi developed extra features, like a run-dialog, ssh-launcher and can act as a drop-in dmenu replacement, making it a very versatile tool.

Clipboard

Selecting any text in Linux copies it and scroll-wheel middle click pastes it, separate to the Ctrl-c Ctrl-v clipboard. This means double clicking a non-line broke sentence copies it to the middle click paste clipboard.

This most used selection is the PRIMARY selection, and is used when the user selects some data. The CLIPBOARD selection is used when the user selects some data and explicitly requests it to be "copied" to the clipboard, such as by invoking "Copy" under the "Edit" menu of an application. An associated request of "Paste" results in the data of the CLIPBOARD selection being used.

"The PRIMARY selection is used when you select some text with the mouse. You usually paste it using the middle button. The CLIPBOARD selection is used when you copy text by using, for example, the Edit/Copy menu. You may paste it using the Edit/Paste menu."

Software

xclip

  • xclip is a command line interface to the X11 clipboard. It can also be used for copying files, as an alternative to sftp/scp, thus avoiding password prompts when X11 forwarding has already been setup.

Autocutsel

  • Autocutsel tracks changes in the server's cutbuffer and CLIPBOARD selection. When the CLIPBOARD is changed, it updates the cutbuffer. When the cutbuffer is changed, it owns the CLIPBOARD selection. The cutbuffer and CLIPBOARD selection are always synchronized. Since the VNC client synchronizes the Windows' clipboard and the server's cutbuffer, all three "clipboards" are always kept synchronized.

xcmenu

XSel

  • XSel - a command-line program for getting and setting the contents of the X selection. Normally this is only accessible by manually highlighting information and pasting it with the middle mouse button.

CopyQ

  • CopyQ is clipboard manager with searchable and editable history.

Parcellite

  • Parcellite is a lightweight GTK+ clipboard manager. This is a stripped down, basic-features-only clipboard manager with a small memory footprint for those who like simplicity.

Future

Wayland

  • Wayland is intended as a simpler replacement for X, easier to develop and maintain. GNOME and KDE are expected to be ported to it. Wayland is a protocol for a compositor to talk to its clients as well as a C library implementation of that protocol. The compositor can be a standalone display server running on Linux kernel modesetting and evdev input devices, an X application, or a wayland client itself. The clients can be traditional applications, X servers (rootless or fullscreen) or other display servers.

Part of the Wayland project is also the Weston reference implementation of a Wayland compositor. Weston can run as an X client or under Linux KMS and ships with a few demo clients. The Weston compositor is a minimal and fast compositor and is suitable for many embedded and mobile use cases.
