The Ubuntu project has released beta version 8.04 and available for download from the official project web site.
The Ubuntu developers are moving very quickly to bring you the absolute latest and greatest software the open source community has to offer. New feature includes:

+ GNOME 2.22

+ Linux kernel 2.6.24.

+ Firefox 3 beta

+ PulseAudio

+ Vinagre VNC client

+ Brasero CD/DVD burning application

+ There is a new installation option for Windows users. Wubi allows users to install and uninstall Ubuntu like any other Windows application. It does not require a dedicated partition, nor does it affect the existing bootloader, yet users can experience a dual-boot setup almost identical to a full installation.

The final stable version will be released in April 2008. Download cutting edge version from official mirror.

How to: Enable and Tag Files / Directories in Gnome Linux Desktop

Posted on in Categories Linux, Linux desktop, Ubuntu Linux last updated October 24, 2007

I’ve been looking for something like this. One brand new feature of gutsy is that tracker, a desktop indexer like google desktop, runs by default. Tracker also supports taxonomy for your files and folders but this feature is not yet integrated into gnome. But wait…you can have it anyway in a few simple steps

I turn my Linux computer off and when I turn it on it runs disk check (fsck) on hard disk. Why?

A typical question asked by many new Linux users. The answer is pretty simple:

Your partitions are not being unmounted properly when you last shutdown the Linux desktop. Linux needs to shutdown properly (I’m sure this applies to Windows and Mac OS too) before powered off. If you skip this step there could be data loss.

If you are using text based session (CLI), type following command as privileged user:
shutdown -h now
OR
halt

If you are using GUI (KDE / Gnome or any other Windows Manager) click on System > Quit button. Look out for shutdown button.

Do not unplug the power supply. Also use UPS (Uninterruptible power supply) to protect data and to avoid other problems. I recommend APC ups for continuous supply of electric power.

Updated for accuracy.

Gnome per user language encoding configuration using .dmrc file

Posted on in Categories Gnome, Howto, Linux, Linux desktop last updated August 27, 2007

Sometime you may see different language encoding in X than on your console (tty) prompt. Sometime two different user need two have different language encodings.

~/.dmrc file – Per-user language support

In theory this file should be shared between GDM (Gnome) and KDM (KDE), so users only have to configure things once. This is a standard .ini kind / style configuration file. It has only one section called [Desktop] which has two keys: Session and Language. There are some per user configuration settings that control how GDM behaves. GDM is picky about the file ownership and permissions of the user files it will access, and will ignore files if they are not owned by the user or files that have group/world write permission. Normally GDM will write this file when the user logs in for the first time, and rewrite it if the user chooses to change their default values on a subsequent login.

Setup language encoding in X

Defining LANG variable is not sufficient, you need to setup language encoding using ~/.dmrc file.
cat ~/.dmrc
Output:

[Desktop]
Session=gnome
Language=cs_CZ.UTF-8

Refer to Gnome Display Manager Reference Manual for more information.
