Ubuntu 9.04 introduces a change to the handling of package updates, launching update-manager directly instead of displaying a notification icon in the GNOME panel. Users will still be notified of security updates on a daily basis, but for updates that are not security-related, users will only be prompted once a week.Users who wish to continue receiving update notifications in the previous manner can restore the earlier behavior using the following command:

gconftool -s –type bool /apps/update-notifier/auto_launch false

Seems in Tomboy 1.0 the location of the .note files has changed, so if you’re looking to share between versions or have updated from Ubuntu Jaunty to Karmic, there is no longer a ~/.tomboy folder.

There is a ~/.config/tomboy folder for the application add-ins and the manifest.xml file.

and there is a ~/.local/share/tomboy folder where the *.note files reside.

For those who use Ubuntu’s inclusion of Tomboy notes, the easiest way to synchronize and share your notes automatically with all your Ubuntu computers is by using your Ubuntu One account rather than WebDAV or SSH. Ubuntu One is a Dropbox type of service by Canonical.

Latest version of Gnome Nautilus come by defaut with the “spatial mode”, and i hate the fact it open another window for every click. Though it is not too hard to disable nautilus spatial: use gconf-editor and set /apps/nautilus/preferences/always_use_browser to true.

Or

gconftool-2 –type bool –set /apps/nautilus/preferences/always_use_browser true

While the Linux find command has a number of uses, the most obvious being looking for files matching full or partial names, the one often underused option is to use it to locate old files. To show all files in a directory older than 14  days:

find /var/crap_files/* -mtime +14 -print

An even more powerful option is to use the -exec switch which allows you to delete old files. To delete all files in /var/crap_files/ older than 7 days:

find /var/crap_files/* -mtime +14 -exec /bin/rm -rf {} \; 2>/dev/null 1>&2

Simply run the command:

sudo modprobe -r pcspkr

or you can set it as a persistent change by adding the module to your system driver blacklist, available at:

/etc/modprobe.d/blacklist

simply append the line “blacklist pcspkr” for that driver to be disregarded at every boot.

Ubuntu Jaunty introduced the new annoying notification system, and by default made pidgin hook into it.  So every non-focused IM you get appears in the upper right hand corner of the screen, completely missing the point of being minimized.

This “annoyance” can be easily fixed by disabling the libnotify plugin within the Pidgin plugins manager. To disable this system go to Tools > Plugins and untick the checkbox next to “Libnotify Popups”.

Also, if you’d prefer, you can try to customize the pop-up behavior by selecting the “Configure Plugin” button.

vim /etc/sofficerc and edit the line Logo=1 to Logo=0

Tor is a free software implementation of second-generation onion routing – a system which claims to enable its users to communicate anonymously on the Internet.  Its primary goal is to protect its users against traffic analysis attacks.  The Tor Project’s home page has a great simplified write up about how Tor actually works here: http://www.torproject.org/overview.html.en

Originally sponsored by the US Naval Research Laboratory, Tor became an Electronic Frontier Foundation (EFF) project in late 2004, and the EFF supported Tor financially until November 2005. Tor software is now developed by the Tor Project, which since December 2006 is a research/education non-profit organization based in the United States of America that receives a diverse base of financial support.

Getting Tor working both as a client and as a server is no sweat on Arch Linux and below are the steps.

Lets say you installed a new window manager, Musca for instance.  And upon installation, no GDM or KDM session was created so you cannot log into it.  Solving this is rather simple.

cd over to /usr/share/xsessions/

if you ls the directory you’ll see several *.desktop files.  Fluxbox’s looks like this:

[Desktop Entry]
Encoding=UTF-8
Name=Fluxbox
Comment=Highly configurable and low resource X11 Window manager
Exec=/usr/bin/startfluxbox
Terminal=False
TryExec=/usr/bin/startfluxbox
Type=Application

[Window Manager]
SessionManaged=true

All you really need to do is the following:

cp /usr/share/xsessions/fluxbox.desktop /usr/share/xsessions/musca.desktop
then modify musca.desktop in a text editor so it looks like the following:

[Desktop Entry]
Encoding=UTF-8
Name=Musca
Comment= Kickass tiling window manager
Exec=/usr/bin/musca
Terminal=False
TryExec=/usr/bin/musca
Type=Application
