Customize Raspbian Jessie PIXEL: still 3 tips [Full Guide]


tux_statue then the output PIXEL I had proposed 14 tips to customize your system.
This article has been read a lot and generated comments and questions.
Here are a few more things that will allow you to adapt your system to your needs best: use virtual desktops, the icon of Chromium, and change video resolution. This is what you will find in this article.

use several virtual desktops with Raspbian PIXEL


Michel pointed out that virtual offices he used in Debian have disappeared from Raspbian. He would like to find them because he has my work habits and wants to find them on my Raspberry Pi.

I propose to add this feature that may interest you if you don’t have two or more screens – 🙂 – ( no room, not the means, not like…) ). everyone has not necessarily useful, but it is strongly used to group windows by activities, for example, an office to house the internet browser and the instant messaging client, a work desk for Python, Scratch…


install the Manager of virtual offices


bureaux_virtuels_01


click with the right button of the mouse on the taskbar. In the menu that opens select add/remove elements of the dashboard .


bureaux_virtuels_02 window Preferences of the dashboard opens. Click on the button Add (right column of the window). The list of the elements that it is possible to add. Select virtual desktops Manager and click the Add at the bottom of this window.


bureaux_virtuels_03 the Manager of offices virtual appears at the top right of the screen as well as in the list of applets, this time downstairs. I advise you to add at least one space to shift slightly the icon. Click again on the button Add and select space (at the bottom of the list) and then again the button Add at the bottom of the window. It will not help much… but it’s prettier 🙂 you can also move the icon with the up and down buttons. Make sure you have a space before and space after. Always for aesthetics.


you will notice that in the design of the virtual office is represented the window that is open on the screen, but in miniature. Click on the virtual desktop. Nothing is happening 🙁
Bin Yes, put the icon in place but nothing to manage these offices. To install obconf for this.


obconf = OpenBox Configuration dixit Ubuntu :


Openbox is a window manager extremely fast, flexible, and enjoyable. This minimal graphic interface is consistent in more ways than one. Very light, it is sufficient unto itself and also allows to greatly speed up the responsiveness of Gnome when she replaces Metacity . She doesn’t have a default dashboard, but it is possible to access the windows with the shortcut alt + tab, or by adding a custom dashboard. :-) Openbox is a powerful tool that is limited only by the imagination of the user!


make the update of your distribution ( sudo apt – get update and sudo apt – get upgrade ) and then install obconf :


[$19459036]pi@raspberrypi:~ sudo apt – get install obconf reading lists of packages…] Done building the tree of dependencies reading state information… Fact the following extra packages will be installed: libglade2-0 the NEW following packages will be installed: libglade2-0 obconf 0 updated, 2 newly installed, 0 to remove and 0 not updated.

It is necessary to take 240 KB in the archives.

After this operation, 941 KB of additional disk space will be used.

Do you want to continue? [O/n]

answer many and installation starts. It’s pretty fast.


once the installation is finished, you can find obconf in the menu Preferences . You can also run it from a terminal by typing obconf .


bureaux_virtuels_11 the OpenBox configuration window opens. You will have access to a whole bunch of your PIXEL desktop settings. I’ll let you explore them. Here we deal with virtual offices 🙂


bureaux_virtuels_04_600px


to the left of the window click Office to access the setting window.


bureaux_virtuels_05_600px we see that the number of offices is here set to… 1. This explains why we can not change desktop 😉
change the value and then go to 2 (you can put more if needed).


bureaux_virtuels_06_600px you get 2 offices whose names are… (desktop without name) . click the first and name. I called mine Internet . Do the same for the second. I called him programming .


bureau de Raspbian PIXEL avec un navigateur chrome et une fenĂȘtre Gpredict on the desktop of PIXEL I opened a Chromium browser and window Gpredict ( now Soyuz is to dock with the ISS 🙂 allows me to follow the path of the ISS ). If you look at the top right of the screen you see the first office and two windows that are open on:


bureaux_virtuels_08 notice that windows comply with the proportions of real windows and that Chromium has the same right to an icon. Click on one of the miniature windows and take on the next office… On the screen of the Raspberry Pi window disappears and is found on the other office. It will be the same on the screen when a window out of the screen, it changes automatically office… To move from one office to the next click on the corresponding icon… Simply! Bring back the window that you had moved in its place 🙂




never to tire us out!


fatigue Don’t tell anyone, I’ll give you a shortcut that avoids the arm up to the mouse, move the mouse to move the cursor at the top right of the screen and click on one of the two icons… On the keyboard CTRL + ALT + right arrow or CTRL + ALT + left arrow do the same thing much more quickly and without unnecessary gestures 😀


bureaux_virtuels_09_600px on the second desktop programming I open Scratch and the Sense Hat Simulator. Let’s look at how all this appears in our icons.


bureaux_virtuels_10 here again the Office Windows are similar to those of the actual screen. The Active Desktop is colored in blue, the idle is gray. As you will notice, the use of virtual offices is limited to the open window that can appear on the different offices. Regarding the icons placed on the office they will be the same regardless of the open office.


show Chromium icon in the taskbar of PIXEL


bureaux_virtuels_12 annoys you, you have two different icons for the same application?
Me, if! Why the hell they tried to embellish the GUI, to add an icon of Chromium, to finally let in the taskbar a sensible thing represent a globe and Web browsing?


I propose to remedy this and to display the icon of Chromium in the taskbar.


icone_chromium_01


start to click with the right button of the mouse on the launch of applications (for example on the Internet icon). Click launch of applications settings .


icone_chromium_02


the setting of the application launch bar window opens, normally Web Browser is selected by default in the left column ( pitching ). If this isn’t the case, made a click on it.


icone_chromium_03


click the remove of the Central column and the icon of the Web Browse disappears.


icone_chromium_04


in the right column ( Applications ), click on the category Internet to unroll it and choose browser Web Chromium .


icone_chromium_05


click on the Add button in the center column. The Web browser is found in the column of the launchers. But it is at the bottom of the column and the icon will not be in its usual place.


icone_chromium_06


use the button ride to bring the icon of the browser in its usual place at the top of the list.


icone_chromium_07 your desktop is now adorned with a representative icon really the Chromium browser.


change the resolution of the video output of Raspbian PIXEL


so here I admit, this trick has already published on the blog . It seemed interesting to extract it from the article in which it is to present this series of stuff to know.


the problem: my Raspberry Pi is connected on an iiyama monitor whose resolution is 1920 × 1080. Great as the full HD of the Raspberry Pi is well used. On my PC, one on which I write now, I use VNC viewer to connect to the Raspberry Pi, my display and achieve wonderful screenshots you see in this article…
The problem is that my PC is connected to a HP monitor whose resolution is 1680 × 1050 pixels… You can guess the rest: I can never get my Raspberry Pi screen displayed on the PC 🙁
forced to juggle the elevators, the position of the window to find the area that interests me.


tell me why not to cross the screens? The answer is: because! So the solution is to lower the resolution of the Raspberry Pi a little to this kind of manipulation so that the screen that is displayed can fit entirely on the PC screen.


Let’s force the resolution to a value that we becomes on the Raspberry Pi. The Raspberry Pi will display a screen to size, which will be sent to the PC via VNC Viewer.


open the /boot/config.txt file, locate and change the following lines:


 # uncomment if hdmi is not detected and display composite is being output hdmi_force_hotplug = 1 # uncomment to force a specific HDMI mode (this will force VGA) hdmi_group = 2 hdmi_mode = 28 

hdmi_mode = 28 corresponds to 1200 × 800 pixels. If you want another resolution RTFM or use one of these


hdmi_mode = 9 800 × 600
hdmi_mode = 16 1024 × 768
hdmi_mode = 23 1280 × 768
hdmi_mode = 28 1280 × 800
hdmi_mode = 35 1280 × 1024
hdmi_mode = 51 1600 × 1200
hdmi_mode = 69 1920 × 1200


then what happens after a reboot?


1280x800 perfect now it fits on my PC screen and I’ll save moving windows… and energy 🙂


the advantage with Linux is that you can adapt the system to their needs or tastes. These three “tips and tricks” for Raspbian PIXEL will allow you to better enjoy your Raspberry Pi.
