Checking the boot messages on Debian
2007-12-16 14:36:00
Sometimes when a machine is booting up with Linux Operating System, some errors appears on the console while booting up, but they just pass too fast for one to read them. Therefore you need look at those messages somewhere else. If you are using Debian , you can enable boot logging so all the messages send to console while booting will also be sent to a file that you can later examine. Note for Ubuntu: Since Feisty, it seems that do not include bootlogd anymore, and the boot messages are now copied to: //var/log/dmesg from kernel's ring buffer, the script that does this is: /etc/init.d/bootmisc.sh To enable this behavior which is off by default edit the file: /etc/default/bootlogd The default content of this file is: # Run bootlogd at startup ? BOOTLOGD_ENABLE=No just change the No to Yes and the bootlogd command will start sending all messages to a file, which by default is: /var/log/boot. You can also check /var/log/dmesg on Debian, or use the dmesg command, when using this com...

Debian - Origin of the names -
2007-12-14 16:07:00
The Debian project founded on 1993 by Ian Murdock was named that way because of the three first letters of his wife's name Deborah and his own name Ian Debian. Later on 1996 Bruce Perens took the command of the project, it appears that he worked at that time in Pixar and since that year all the next Debian releases came with a code name of one character of Toy Story sid (The kid who destroys toys) buzz (Buzz Lightyear) Debian 1.1 rex (The T-Rex) Debian 1.2 bo (Bo Peep) Debian 1.3 Hamm Debian 2.0 slink (Slinky the dog) Debian 2.1 potato (Mr. Potato) Debian 2.2 woody (the Cowboy) Debian 3.0 sarge (The Sargent to the green squad) Debian 3.1 Etch Debian 4.1 This info was translated from El Igloo a Spanish blog about Linux, recommended for those who reads Spanish.

KDE4 use of memory vs KDE3
2007-12-14 13:22:00
There are two stories about the use of memory by KDE4 vs the use of memory of KDE3, they have somehow different information, actually opposite. The two "studies" comes from the same author on its first test, he used KSysguard applications to measure the amount of memory used by both versions of KDE and the results showed that KDE 4 uses 40% less memory than KDE 3, this story is now on Digg and Slashdot. digg Slashdot It is even on reddit, pointing to the slashdot article, well this making everybody think that KDE 4 with composite on uses less memory than KDE 3.5, the same author of the first post, made another one as a correction to the first one, this time he used exmap to measure the memory used by both KDE 4 and KDE 3, this is a really good test, but now it shows that KDE 4 uses more memory than KDE 3. KDE 4 requires more memory. In similar conditions KDE 3 consumed 97 MB on memory, whereas KDE 4 about 170 MB but take into account that KDE4 has composite on, it will be great if s...

How to install Graphic Interface - Gnome or KDE - on minimal Debian
2007-12-12 15:13:00
If you ever installed Debian you should know this screen. This appears when you install your Debian Linux operating system from the NetInstall CD, sometimes you may want to select nothing there, and just install the minimum installation. Once your installation is finished, and you want to install some task, like Desktop Environment just call the application again as root: tasksel thats all you need, now select the task you need to install and voila! This is useful in some of the following scenarios. Your CPE modem assigns an IP with DHCP but the DNS it assigns (itself) does not work, (that is my case) so you can finish you base installation, assign a fixed DNS server to your Debian and continue with the installation of the other packages You may want to install Lenny or Sid, so install Etch base system, change the source.list to whatever you need, and once upgraded, continue with the installation of the desired tasks You have no internet connection at that time, and want to insta...

Modifying your screen resolution
2007-12-12 12:18:00
Yesterday after an upgrade of my Debian system the resolution of my screen switched to 800x600, I checked my xorg.conf configuration and everything was OK, but fortunately in Linux everything has an easy solution, what I needed to do was: dpkg-reconfigure xserver-xorg and Debian took care of the configurations, after that the option 1024x768 appeared again in my Gnome options.

The Desktop Battle - Vista and Ubuntu -
2007-12-09 02:51:00
About a week ago, my good friend of PolishLinux posted a thread (Yes it is now a thread, like in a forum) about Ubuntu (Gutsy Gibbon) and Vista (Business Edition), in the battlefield of Desktop Oriented Operating systems. He stated that: It may be a brave opinion but I predict that Ubuntu Linux and Windows Vista are going to be the two operating systems that will take over the largest chunk of the desktop OS market during the next couple of years And then he made a side by side comparison of some aspects he thinks are the most important for the "John Doe" user. I am not going to say if he is right in the final punctuation: Ubuntu 4:2 Vista As I have never used Vista regularly and I have stop using XP some three years ago. (BTW, I am happy I could), but there are two things he is actually right. Ubuntu, and not because it is the best Linux distro (There is no best distro for me) but because all the marketing and money involved, and because they are giving the final user what he want...

KDE 4 - Which Distro will be the first to Offer KDE 4?
2007-12-09 01:27:00
I am not a KDE user, but used to be, and after seeing so much about KDE4 I am really thinking about start using it again. But the question Beineri ask is. Which Distro will be first to ship KDE4? According to him as soon as it is released lots of distributions will start to offer it, well maybe that will not occur with my favorite Linux Distro (Debian) even though I am using Lenny in my Laptop. Maybe Fedora, Ubuntu, Mandriva, Sabayon and others like those will offer KDE4 as soon as it is available, also CentOS is another issue, theses Systems, Gentoo, CentOS, Debian, which are more focused on stability will not offer KDE 4 as soon as it is available, but others focused on Desktop applications, as I said, Fedora, Ubuntu, Mandriva, will offer it as soon as possible. That is of course my humble opinion.

Maybe a lot of people already know this, but I will write it down here, in case anyone forget it, or of somebody does not know already. To upgrade the Linux Debian Stable Etch to testing Lenny, just need to follow these two steps. 1. Edit sources.list sudo vi /etc/apt/sources.list and change all words etch for lenny, or stable for testing 2. Update and upgrade sudo apt-get update && apt-get dist-upgrade that is all, this also work if you want to go from lenny to sid, just change your sources.list accordingly. It is also better if you start your Debian Linux in text mode to do this, so GDM or KDM could be restarted without problems.
