In a terminal type:

sudo gedit /etc/apt/sources.list

This will bring up your source list. then add these two lines to the end of your source list:

deb http://ppa.launchpad.net/netbook-remix-team/ubuntu intrepid main
deb-src http://ppa.launchpad.net/netbook-remix-team/ubuntu intrepid main

In a terminal type:

sudo apt-get update

To update your source lists.

Then Install the Netbook Remix packages

sudo apt-get install go-home-applet human-netbook-theme maximus netbook-launcher window-picker-applet

Now you need to restart the Gnome display manager.
In a terminal type:

sudo /etc/init.d/gdm restart

After the reset you will see the UME-Launcher running.

To maximize your workspace area, you might want to remove the bottom pane, by right clicking the bottom panel and selecting the “Delete this Panel” option.

To get the most from your top panel you will want to add functions to your top panel. Right click the top panel and select the “Add to the Panel” option. Some suggestions include: GoHomeApplet, WindowPickerApplet, NotificationArea, and VolumeControl.

Out of memory? Did you upgrade your OS recently? Then carefully have a look at ps -auwx output for memory consumption.

Today I found that initscripts package owned minilogd was eating up almost 70% of the server resources on a VPS running on OpenVZ virtualization. After reading a bit about it on the internet I found that it’s used by syslog and I had to restart syslog service to get the issue sorted out.

Alway make good use of the tools given by Linux to monitor the processes. They will surely help you to knockdown the problem that you’re facing.

Happy Hacking!

It’s really cute to see the new face of gparted on Ubuntu Intrepid Ibex. No issues with NTFS resize. In turn it’s quite fast when compared to earlier resizes which I had done on dozens of laptops.

Above is the picture of Ubuntu Installation wizard paritioning stage. That also has been made colorful.

If you’re running out of RAM, swap and if there is no more room to create a new swap partition, you’re still left with one more option. Create a swapfile. Here are the steps to follow.

1. Determine the size of the new swap file and multiple by 1024 to determine the block size. For example, the block size of a 64 MB swap file is 65536.
2. At a shell prompt as root, type the following command with count being equal to the desired block size:
   dd if=/dev/zero of=/swapfile bs=1024 count=65536
3. Setup the swap file with the command:
   mkswap /swapfile
4. To enable the swap file immediately but not automatically at boot time:
   swapon /swapfile
5. To enable it at boot time, edit /etc/fstab to include:
   

   /swapfile swap swap defaults 0 0

   The next time the system boots, it will enable the new swap file.

6. After adding the new swap file and enabling it, make sure it is enabled by viewing the output of the command cat /proc/swaps or free.

How do I repair/rebuild all Qmail configuration files and restore settings for all mailboxes?

Resolution:
This can be done with Plesk mchk utility:

# /usr/local/psa/admin/bin/mchk

Synopsis:
mchk [OPTION]
–without-spam - restore all settings except for SpamAssassin configuration
–with-spam - restore all settings
–spam-only - restore only SpamAssassin settings

This utility rebuilds in line with Plesk database Qmail control files in the /var/qmail/control, /var/qmail/users directories and mail users’ settings. Also, it sets proper ownership/permissions for all mailboxes (/var/qmail/mailnames/*).

Example:
