If you want to restrict users from appearing on lightdm login list, proceed as shown below :

1 – Edit the file /etc/lightdm/users.conf with root privileges.

$ sudo vi /etc/lightdm/users.conf

2 – Add the user name that you don’t need to be shown in the line hidden-users=nobody nobody4 noaccess oracle

3 – Save. Next time you log in you will not see that user in the login list.

PS. Users having shell = /bin/false e /usr/sbin/nologin will not be listed by default.

Nautilus Tree Panel.

Filed Under ( by Laudeci Oliveira on 18-08-2011

I am testing Ubuntu 11.10 and one thing that I didn’t like is the left panel showing Places instead of tree.

Now, if you are like me and want to navigate using a tree panel, run the following command in the terminal.

gsettings set org.gnome.nautilus.window-state side-pane-view "tree"

If you want to change it using a graphical application, install  dconf-tools, start dconf-editor and

navigate to org.gnome.nautilus.window-state,  change the value of side-pane-view to “tree”.

Now your Nautilus will look like this:

PS.: Ubuntu 11.10 Oneiric Ocelot still in Alpha3, not recommended to be used in a production environment.


Quicklist Editor for Unity Launcher

Filed Under (Pessoal, Python, by Laudeci Oliveira on 05-05-2011

Creating a custom launcher for unity is simple. Quicklists provide a easy and efficient way to quickly access commonly used tasks for a specific application.

The steps to create a custom launcher is easy.

  1. Right-click on your desktop and click create a launcher.
  2. Edit the .desktop file using a text editor and using this you can create static quicklist for the Unity.

After read that on and play around with some custom launchers, I started a project to make it even easier.

The Quicklist Editor for Unity Launcher.

It still in the early development phase, only a 2 days work in my spare time and when my first son (born 30 days ago) allows me to!

Ursinha and I are working on this,  and we expect to release the first beta by next Monday.

You can find the project page on Launchpad:

Contributing Back to Gnome?

Filed Under (Pessoal, by Laudeci Oliveira on 26-05-2010

I was reading about the Ubuntu Control Center-UCC fever from a lot of blogs and twitter from people linked to the Ubuntu Community.

The author did a very good job. He made  glowing lights come out from people’s eyes staring at the application layout looking very Ubuntuish.

Oh, its beautiful, We need something like that on Ubuntu!!!!

Gnome has an application that does the same work as the shine new Ubuntu Control Center –based on Mandriva’s Control Center– does, take a look at the gnome-control-center.

Ubuntu Control Center

Gnome Control Center

Personally, I think that the right path is something like “Oh, good, can we work together with Gnome and improve gnome-control-center?”

That would make more sense to me than that wooows I’ve read last days.

Contribute to join, not to be apart!!!

Conky on Ubuntu 10.04 LTS Beta 1

Filed Under (Geral, Pessoal, Python, by Laudeci Oliveira on 22-03-2010

Well, as asked  in my last post, here comes the steps used to get that conky layout.

  1. Download the Another conky config 0.02 (newer than mine).
  2. Extract the file 121331-conkypatch.tar.gz.
  3. Edit the conky.conf file,
    1. change own_window_type override to own_window_type root (For some reason override will not draw on desktop in lucid).
    2. change ${image ~/.conkypatch/icons/logo.png -p 18,0 -s 45×45} to ${image /usr/share/icons/gnome/32×32/places/start-here.png -p 11,7}
    3. Add the following line to the end:
    4. ${font Martin Vogel’s Symbols:size=14}B${font}${voffset -1}Mail: ${alignr}${font DejaVu Sans:pixelsize=10:style=Bold}${execi 10 python ~/.conkyScripts/ n} ${color2}mail(s)

  4. Save the file as .conkyrc in your home folder.
  5. Download the wallpaper used here.
  6. Download the gmail script here and save it to the ~/.conkyScripts folder (Don’t forget to set your username and password in the script).
  7. You can download and install these fonts too.

My conky file can be downloaded here.

Thank you Adrian patchpl for this beautifull conky config and Enrico for the Purple sensation wallpaper.
