Video Thumbnail in Dolphin – Fedora 23/24

After a long, long, long time, finally I can view my videos thumbnails in Dolphin.

I reported a Bug in RPMFusion Bugzilla back in Januay 2016 and earlier this morning I got the surpise that it was Resolved!

I want to thank Leigh Scott for getting this done. I’m really happy about it, since I have lots and lots of videos and being able to look at a small thumbnail is really helpful.

So, to get the package installed, all you need to do is:

$sudo dnf install ffmpegthumbs

After that, just need to enable it in Dolphin by going to Preferences > Configure Dolphin > General > Previews > Video files (ffmpegthumbs) and that’s it!

Thanks again for making this happen.

Fix Video Thumbnails in Dolphin 15.08.1 (KDE 5.17.0) in Fedora 23

When updating KDE in my Fedora 23, I lost the video previews in Dolphin. Even after installing ffmpegthumbs did not work.

So here is the solution:

sudo cp /usr/share/kde4/services/ffmpegthumbs.desktop /usr/share/kservices5/
sudo cp /usr/lib64/kde4/ /usr/lib64/qt5/plugins/

You need to have installed ffmpegthumbs for this to work, to install it:

sudo dnf install ffmpegthumbs

And you need to enable the video preview again in Dolphin.

zsh with oh-my-zsh

Zsh is a shell designed for interactive use.

To install it in Fedora:

yum install zsh

Once installed, you can run it with:


This will create a new file: ~/.zshrc with all the defaults configurations.


oh-my-zsh it’s a community-driven framework for managing your zsh configuration. Includes a bunch of plugins and themes.

To install it:

curl -L | bash

To set zsh as the default shell:

chsh -s /bin/zsh

And restart your terminal.

And for sharing or synchronizing history between Zsh and Bash:

$ cat ~/.histfile >> ~/.bash_history
$ youreditor ~/.zshrc
# Here change your config to:
$ rm ~/.histfile

For themes and plugins for oh-my-zsh:


And that’s it.

Enjoy your zsh.

FUDCon Managua 2014

Well, FUDCon Managua is now over. It was awesome!!!

There were many interesting talks by Fedora Contributors and Users. I was able to be in a few of them and meet really interesting and kind people.

Some of the talks I attended were: oVirt, Nagios, Flask, Virtualization with KVM, OpenStack, SELinux, Icaro, among others.

Thanks to the people that gave time and energy into this, we really appreciate it.

I will be posting more information later, with URL to the talks when they are available online.

Now, some pictures I was able to take during the event.








Asus G74SX-DH71 Keyboard lights Function Keys in KDE (Debian and Fedora)

I was trying for a while to make my Function Keys (volume, keyboard lights, etc) work in KDE 4.x, and I was finely able to do it with a *funny* workaround. It turns out that the Fn keys works just fine in Gnome, so I dig a little bit and found that the responsible of making this work is a small daemon called gnome-settings-daemon… So it’s just a matter of starting up this daemon in KDE and that’s it.

So, for doing that I just needed to add the next bash file:

$vi ~/.kde/Autostart/

and add this line:

For Debian:


For Fedora:


we save the file and then add exec permissions

$chmod u+x ~/.kde/Autostart/

Now you need to logout and login again and that’s it.

For getting the screen brightness function keys working properly, we need to edit our xorg.conf file:

#vi /etc/X11/xorg.conf

Under the section “Device” we need to add:

Option "RegistryDwords" "EnableBrightnessControl=1"

So, at the end, our “Device” section should look similar to:

Section "Device"                                                                                                                     
    Identifier  "Video Card"                                                                                                         
    Driver      "nvidia"                                                                                                             
    Option "RegistryDwords" "EnableBrightnessControl=1"                                                                              

You need to reboot in order to get this working.

Hope that works for you. 🙂
