phoronix online forums

Yesterday I discovered phoronix.com, an online community dedicated to all technical things, and especially Linux.

I found the online forums extremely helpful.

Ubuntu 8.04

I downloaded the latest Ubuntu bits last night and burned them onto a DVD. I am very impressed by the user experience Ubuntu creates for its users — its very simple. This morning I only spent a couple of hours configuring my dual-screen setup and everything else seems to be working just right.

I especially like the way it recognized my network storage server, so that i could retrieve files that I had backed up.  Now i can get to my real work :-)


dual monitors xorg.conf

I got dual monitors working on my Linux desktop. I ended up downloading the proprietary ATI driver then using the aticonfig command. This works on Fedora Core 8 with an ATI Radeon X700 graphics card and 2 monitors.

reset xorg.conf

I screwed up my xorg.conf file today while trying to setup dual monitors on my Linux desktop. When you have a corrupt xorg.conf file, the computer usually boots into the Console with no graphical interface. (runlevel 3)

Using a second computer, I found a handy command which allowed me to reset the xorg.conf

Log in as root and type:
system-config-display –noui –reconfig –output=/etc/X11/xorg.conf

This should get you back into your system in a graphical mode (runlevel 5). I hope this helps anyone out there trying to get dual monitors working on Linux!


Looking back after one year of using Linux

I’ve been using Linux for about a year now so I thought I’d write a quick blurb about my experience so far.

I decided to start with Novel’s openSUSE to run my own web server. The server setup was easy thanks to Yast. A few months later, I switched my desktop PC from a beta copy of Windows Vista to Fedora Core 6. This is now my main computer at home. A couple of months after that, I installed Ubuntu on my laptop.

Maintaining 3 different Linux systems in the course of one year has given me a pretty good understanding of a typical Linux system. I have a great deal of appreciation for all the people who contribute to these projects.

Will I continue to use Linux? yes, absolutely! and I plan give back to the community as I learn more.

Linux for kids

I’ve been trying to get my younger brother into computers ever since he was 8. Back then I gave him his 1st hand me down computer; a Pentium III with decent hardware and Windows XP Pro.

Last weekend, he came over to my house and saw the latest computer I built. “What’s that?” he said, pointing to the blue LED lights that were clearly visible from the transparent case. “My computer”, I responded as I proceeded to start it up.

As the system was booting up I pointed out to him that the operating system was called Linux and that I was using Fedora. I sat him down and started one of my favorite Linux games, Nibbles. Later that day, I asked him if he liked the computer and he said yes.

Now that my brother is 10, I’ve decided to upgrade his system with one that has a faster processor and more memory (I’ll spare you with the details). The new system will run Linux of course; but now I’m trying to decide between Fedora and Edubuntu. The challenge is that my mom also needs to use the computer and she is a very different type of user to say the least.

What Linux distro should I install for them? Fedora or Edubuntu?
