Gnome 3 shell themes

If you are using gnome-shell and are bored with the same default theme then read on…. 🙂

By default changing the default theme requires that you modify the files yourself or copy few files to the required directories. Well, if this is not in your scheme of things for changing the theme, a very simple task. Now, you can simply do this with gnome shell extensions.

GPG error on N900 when doing update on command line

If you have added some extra repositories to your Nokia N900 and are trying to do something ( like update, install or any other apt-get operation) you might see some errors or warnings related to the GPG keys. The errors would come because the Public keys for the reporisitories are not present in the gpg database 🙂

sakura – Reaaly good terminal with very few dependencies.

I was searching for something in the Fedora repos and found a really good terminal, sakura. Its very much like Gnome-terminal. I did not find much difference other than using less memory.

To install:

  <td>
    <div class="text codecolorer">
      sudo yum install sakura
    </div>
  </td>
</tr>

and the details of the package:

Arch : i686

Version     : 2.3.8

Release     : 1.fc14

Gnome Tips

Add/Edit GDM Sessions

Each session is a *.desktop file located at /usr/share/xsessions.

GDM appearance

You can change background image, gtk/icon theme by hands (as described at Gnome_2.28_Changes#Configuring_gdm_2.28), or you can use gdm2setup from the AUR.

Tweaking

If your gnome applications seem sluggish and gnome hangs at start-up after killing the previous session, it’s likely you haven’t set your /etc/hosts file correctly and your /etc/hosts file includes:

127.0.0.1       localhost.localdomain     localhost      YOURHOSTNAME

Then run “/bin/hostname YOURHOSTNAME” and “/sbin/ifconfig lo up” as root.

vino – connect to running GNome session like RDP

One thing that all of us Linux users have probably missed is connecting to the running GNome session to see what is going on in the running session. This can be quite handy in couple of situations:

1. Debugging remote sessions – where you do not want a new session, instead want to connect to running session.

2. Maintaining running session from another PC. If you are running some applications on some Linux box and want to gracefully stop it using some commands other than kill -9 then it is best that you connect to the running session, if you are not using screen.

New feature in Gnome/Nautilus

One of the things that I never realized that I am missing in Nautilus until they put the feature in was this. When a file is being copied and there is conflict, there should be option to rename the new file being copied. Also, if the file being copied is image then a small preview/thumbnail would be good.

Yesterday while copying some files, suddenly I noticed that this feature is there now. Pretty useful feature to have. Here’s the screen-shot.
