Ubuntu distros: RAM & CPU usage of Ubuntu, Xubuntu, Kubuntu & Lubuntu

An interesting suggestion came for comparing the RAM & CPU usage of the four Linux sisters: Ubuntu 12.04 LTS, Kubuntu 12.04 LTS, Xubuntu 12.04 LTS & Lubuntu 12.04 LTS.

As mentioned in my previous post, Ubuntu seemed to be the most taxing on CPU & RAM whereas Lubuntu seemed to be the least. The same results are validated when I booted each of them from pen drive and checked the RAM & CPU usage.

To begin with, I won't go into much of technical nitty gritty - you can check it from the ubuntu website itself.

My blog is from end user perspective. I'll share some cool screen shots of ubuntu and highlight the essential improvement ubuntu has made in it's cool new distro.

Unity interface was bad in Ubuntu 11.10 to be honest and I didn't like it at all. I preferred staying back with Ubuntu

A tabular view of the results is given below:

Linux 12.04 LTS adventure tonight: Ubuntu, Xubuntu & Kubuntu

Tonight I am trying out Ubuntu, Xubuntu and Kubuntu 12.04 LTS on my desktop. These are the beta2 versions. I am narrowing down on what distro to install in my HP 2003 era desktop with 1 GB DDR RAM and 2.4 Ghz Pentium 4 processor. It still has enough life to pull off the modern linux OSs.

Already, as mentioned in my previous blog post, I have installed Xubuntu 12.04 LTS in my Asus Eee PC 1101HA

[SOLVED] Precise Pangolin: Asus eee PC Issue with GMD500 & display problem with half screen display

For quite sometime I was trying to load Ubuntu 12.04 LTS beta1 and beta2 to my Asus Eee PC 1101HA with 1.34 Ghz Intel Atom processor and 1 GB DDR3 RAM. Somehow the distro would get installed but not boot to a GUI due to GMD500.

Either it won't  load or even if it loads the display would be half the screen.

Finally I found a way to get around. Once the black screen comes press Ctrl - Alt - F2,

glib lotus notes java memory corruption

Today i updated some packets related to IBM lotus notes and a problem with libraries caused a great and long investigation process to have lotus notes back.


I tried lot of things: reinstalling, purging the packets, installing the same version again... nothing worked. Today i found the solution here.


It says:

[...] After some research I found the problem: libnuma. If this lib exists in the system the Notes Client loads data forever. [...]


the solution is:
apt-get remove libnuma1
