Disable The Universal Access Accessibility Menu In Gnome 3

Edit as root the file /usr/share/gnome-shell/js/ui/panel.js

Look for the following line, (line 37 in my case):

'a11y': imports.ui.status.accessibility.ATIndicator,

Comment it out, so it will look like this :

// 'a11y': imports.ui.status.accessibility.ATIndicator,

Restart gnome-shell :

Press ALT + F2 and type in r and hit Enter to restart the gnome-shell.


Enable Autologin Gdm3

As root edit the file /etc/gdm3/daemon.conf  :

nano /etc/gdm3/daemon.conf

Look for the lines :

#  AutomaticLoginEnable = true
#  AutomaticLogin = user1

Remove the # signs before each line and replace user1 with your own username.

So in my case ( username = eric ) these lines will look like :

AutomaticLoginEnable = true
AutomaticLogin = eric

To see it working switch to tty1 :


Login as root and then :

/etc/init.d/gdm3 restart

Install Pepperflash In Chromium

Go to the Google Chrome Webpage and download the web browser for your processor architecture.
Unpack the deb package ( I used file-roller ) and go to the directory /opt/google/chrome/ .

Select Pepperflash and Extract.

Inside the directory Pepperflash there is a file .

As root :
mv /usr/lib/chromium/plugins

As root edit the file default in /etc/chromium and add this line :

CHROMIUM_FLAGS=" --ppapi-flash-path=/usr/lib/chromium/plugins/"

The whole file will look like this :

# Default settings for chromium. This file is sourced by /bin/sh from
# /usr/bin/chromium

# Options to pass to chromium
CHROMIUM_FLAGS=" --ppapi-flash-path=/usr/lib/chromium/plugins/"

Restart chromium.

Check the setting at chrome:plugins in the address bar ( check +Details ) :

A Minimal Gnome 3 Installation

Download from a Small CD ( here ). No businesscard CD image any longer...

I chose to put the image ( debian-7.1.0-amd64-netinst.iso ) on an USB stick ( see a former post and here ).

This time I decided to go the Graphical install way....

Just follow the's easy enough.

In the next screen I deselected everything....

Install the Grub boot loader to the master boot record.....

After finishing the installation reboot and....just press Enter....

Next screen login as root....

A few adjustments to the sources.list....

nano /etc/apt/sources.list

Add contrib and non-free at the end of all lines....Ctrl+o ( WriteOut ), File Name to Write : sources.list, hit Enter, Ctrl+x ( Exit ).

Then :

nano /etc/apt/apt.conf

Write this line : 

APT::Install-Recommends "false";

Save and exit. First update....

apt-get update 

Install a minimal xserver. My videocard is a Nvidia GeForce GT 330

apt-get install xserver-xorg-input-evdev xserver-xorg-video-nvidia 

I kept an eye on the recommended packages.....

apt-get install nvidia-glx linux-headers-$(uname -r)

Package nvidia-glx will pull in package nvidia-kernel-dkms. Next :

apt-get install gdm3 gnome-session xorg nautilus gnome-terminal gnome-shell-extensions gnome-control-center gnome-tweak-tool alsa-utils pulseaudio gnome-themes 

Next is optional :

apt-get install chromium gthumb gdebi gksu leafpad glipper file-roller nautilus-open-terminal synaptic 

Create a configuration file for the Nvidia card :

nano /etc/X11/xorg.conf   and add these lines :

Section "Device"
        Identifier "My GPU"
        Driver "nvidia"

Now reboot and login !

Some more tweaks :

Add this .fonts.conf file in your home directory.

Create a directory .icons in your home directory and add these icons.

Find more icons here and here....

Create a directory .fonts in your home directory and add these fonts.

Make adjustments in Advanced Settings.

Chromium Show In Folder Not Working

I ran Chromium in a terminal to find out what was happening.
There was a line saying :

/usr/bin/xdg-open 491 /usr/bin/xdg-open gnome-open not found

The problem was a missing package in my minimal Gnome installation : gvfs-bin ,indeed fixed by installing the package gvfs-bin.

sudo apt-get install gvfs-bin

Enable Video Thumbnails With Ffmpegthumbnailer

To enable video thumbnails in Nautilus we need package ffmpegthumbnailer.
As root :

Create a file ffmpeg.thumbnailer in /usr/share/thumbnailers with the following content :

[Thumbnailer Entry]
Exec=ffmpegthumbnailer -s %s -i %i -o %o -c png -f -t 10

After these steps force Nautilus to generate new thumbnails :

rm -rf ~/.thumbnails

And restart Nautilus :

nautilus -q
