Terminal as a transparent wallpaper
There are two popular ways of configuring a Linux terminal to work transparently over a wallpaper, without any borders, menu bars or toolbars. This is very popular among developers because of its practical and coolness factor. Example: using it to view source-code or to get an interactive process status of the system with htop. Something like conky, but not quite.
Tilda is a highly customizable GTK based drop-down terminal emulator, inspired by terminals featured in games like Quake, Doom and Half-Life, where the terminal has no border and is hidden from the desktop till a keyboard shortcut is pressed. To achieve the desired look, edit the configuration as follows:
- Under the General tab, uncheck Always on Top.
- Under Appearance you can edit the height and width to your liking, but make sure you check Enable Transparency and make the Level of Transparency 100%.
- Under Colors tab, chose Green on Black or Personalize.
- Under Scrolling you select Disabled.
Setup by desktop environment
Openbox, Compiz and alike
With versatile window managers like Openbox it is easy to create a terminal on the desktop. Tilda is highly configurable and might be your terminal of choice. Right-click on Tilda and configure the size to your needs, then set transparency to 100%, uncheck the option to start Tilda hidden.
Now you only have to set Tilda as "below" according to your window manager. For Compiz, this is done with the "Rules for Windows"-plugin, for Openbox, add to the "applications"-section of
rc.xml the following lines:
<application name="tilda"> <layer>below</layer> </application>
Et voila, you have a transparent terminal the size of your choice on your desktop, that will not appear in the tasklist and is permanently below.
It is proposed here to install theAUR package which provides control over the placement and the behavior of the terminal window. It can be configured to detect windows as they are created, and match the window to a set of rules. If the window matches the rules, it can perform a series of actions on that window.
Follow the steps below to configure devilspie to catch the terminal emulator on the fly and setup its style as desired:
- 1. Create a devilspie configuration file: it has the extension .ds and is within the
~/.devilspiefolder. This is the default location for configuration.
(if (matches (window_name) "DesktopConsole_1") (begin (stick) (below) (undecorate) (skip_pager) (skip_tasklist) (wintype "dock") (geometry "+240+250") (geometry "954×680") ) )
- 2. Open a gnome-terminal window go to Edit > Profile > New. Name it DesktopConsole_1.
Edit the Profile, to achieve our desired look we will need to edit the default configurations:
Under General tab, uncheck "Show menubar by default in new terminals".
Under Colors tab, choose "Green on Black" (choose whatever you like, i like this).
Under Effects tab, choose "Transparent background". Make sure the scroll is set to "None".
Under Scrolling tab, select "Disabled".
- 3. In this step we will setup devilspie and our custom terminal profile to load on bootup.
Go to Systems > Preferences > Sessions.
Add a new session by using the
+ sign. The first one we will put, "devilspie", in both name and command.
The second session we will put "gnome-terminal", under name and "gnome-terminal --window-with-profile=DesktopConsole_1 --title=DesktopConsole_1", under command. Here we are basically calling gnome-terminal with the custom profile we created earlier.
- 4. Logout/login and you should have your desired look.
You can customize more to fit your needs and style, have more than one terminal; I will leave it to your imagination.
Using wmctrl this can be achieved with the default xfce4-terminal's command line options. The sample script below is rather self-explanatory...
#!/bin/bash xfce4-terminal --hide-borders --hide-toolbar --hide-menubar --title=desktopconsole --geometry=130x44+0+0 & sleep 5 wmctrl -r desktopconsole -b add,below,sticky wmctrl -r desktopconsole -b add,skip_taskbar,skip_pager
By naming the the terminal with --title one can easily identify it's window and add/remove properties through wmctrl accordingly. Setting the size and possition with the --geometry option follows this rule: (Width-in-characters)x(height-in-charactors)+x+y where x and y are the position in pixels offset from the upper-left corner of the display (which starts at +0+0). transparency and disabling the scrollbar can be set through the terminal's preferences menu under the appearance and general tabs. Once the user has the script customized to their needs or wants they can simply mark it as executable (or chmod a+x /path/to/script.sh) then add it to their startup under Applications Menu > Settings > Session and Startup > Applications Autostart.
