Gnome Shell - disable tracker

There is a very handy package that allows disabling Gnome Shell Tracker:


Install it, launch it and see the options it has. I uncheck anything that tells Tracker to index my files (which - indexing on - in my case makes my computer hang up badly).

Flash plugin in Chromium

The only real reason that made me install Google Chrome on Linux was that it came with flash plugin. And Chromium has no flash by default.

To have Flash plugin on Chromium it's sufficient to install pepperflashplugin-nonfree from the distro's repos (in my case it's sudo apt-get install pepperflashplugin-nonfree). That's it. No need for Chrome anymore.

XFCE / Xubuntu - how take a screenshot of a screen area

By default the XFCE that is shipped in Xubuntu (as of Xubuntu 15.04) allows you to press the PrintScreen button and capture the whole screen and press alt + PrintScreen to capture the window in focus. Well, this is obviously not enough. People do need to be able to capture just a portion of the screen, it's an as frequent use case as capturing the whole screen (in my particular case it's even the most frequent use case).

But thanks to the developers of the default screenshot program in XFCE (whatever it is), there is a possibility to make screenshots of a selected screen region - we'll just have to quickly set-up a shortcut for it:

Menu => Settings => Keyboard => Application shortcut => Add => type the command:

xfce4-screenshooter -r

=> press the keys you want to be the shortcut for this action (for me it Shift + PrintScreen) => done.

(Or one could simply run the command xfce4-screenshooter -r by pressing alt + F2 to take a screenshot of an area, but it's obviously faster to create a shortcut).

How to disable window animations on Gnome Shell 3.14 and higher

Launch dconf-editor

Go to the following sections of it:
org => gnome => desktop => interface => uncheck enable-animations

However on my system the windows started moving so briskly with the effects disabled that I actually had to enable them back.

Google Chrome or Chromium didn't shut down correctly on a system with Gnome Shell

On Ubuntu Gnome 14.10 and Sabayon with Gnome Shell I encountered the following situation when launching Google Chrome or Chromium after computer boot - the browsers would say:

"Google Chrome didn't shut down correctly"
"Chromium didn't shut down correctly"

and would offer to restore the previous tabs. Of course, the browsers had been shut down correctly before powering off the system.

Well, the cause of the error turned out to be simpler than I thought:

To stop getting the error uncheck "Continue running background apps when Chromim (Chrome) is closed".

In case you need to allow running background apps in the browsers, well, browse their respective bug-trackers for a relevant bug report and see if there are other solutions, workarounds, etc.

Skype notifications pause Rhythmbox playback

When I run both Skype and Rhythmbox, Rhythmbox is paused every time a Skype notification arrives (on receiving a new incoming message, new file transfer request, incoming call,  etc.). I find it quite annoying.

There are at least 2 ways to resolve the problem I've come across:

1) turn off all Skype notifications - and Rhythmbox is never paused. However it's not a good solution at all :)

2) edit the default.pa file in /etc/pulse/

sudo gedit /etc/pulse/default.pa

find line:

load-module module-role-cork

and comment it:

# load-module module-role-cork

save file.

Log out. Login. Voila.

P.S. The OS used was Sabayon, I've also noticed the solution applies to Fedora as well.
