Fully Qualified Server Name

If you are trying to restart an Apache server running on Ubuntu, Linux Mint or any other Ubuntu derived distro, you will get an warning message that your Apache server does not contain a fully qualified domain name.

Restarting Apache

sudo /etc/init.d/apache2 restart

Warning Message

* Restarting web server apache2
apache2: Could not reliably determine the server's fully qualified domain name, using for ServerName ... waiting apache2: 
Could not reliably determine the server's fully qualified domain name, using for ServerName [ OK ]

To fix this annoying message, you need to set the hostname:

Set Hostname

sudo hostname computername.domain.com

So, the next time you restart the Apache server:

Restart Apache

sudo /etc/init.d/apache2 restart

There are no more warning messages.

No More Messages

* Restarting web server apache2
... waiting                                                              [ OK ]

XRANDR Comes to the Rescue

What could be more frustrating than trying to install Ubuntu or Mint on a new CPU, motherboard, with a built-in graphics card and your display goes south. Here’s the scenario, after the initial flash screens, the screen goes blank. It seems that Xorg is using a screen resolution your monitor does not support.

Why is that? So frustrating. So, my older 19 inch Samsung monitor comes to the rescue. It seems to cope better than my 22 inch HPw220h monitor. The initial screen seems to be twice as big as the monitor supports, hence it doesn’t display properly on certain monitors.

There is one trick, well, a fix to make things all right again. XRANDR comes to the rescue. You will need to perform the following to get your Xorg displaying properly.

  • Hit Ctrl-Alt-F1. This will take you to the terminal screen.
  • Type in XRANDR -s 1024×768. This resets the screen a certain size.
  • Hit Ctrl-Alt-F7. This will take you back to XORG.

You can then make the Xorg changes and make it stick. Once I regained my screen, I was able to reconfigure Xorg to the resolution I wanted, 1680×1050 on my HP monitor.

To make my changes stick, I selected Preferences>Display. Say NO when prompted. Logout and Login.

The new Xorg configuration is now set.

It was a Memory Problem

Who would have thought? The source of my hardware issues this past two weeks was the RAM memory. As I previously wrote in my older post, I was experiencing a kernel panic. The symptoms were that my keyboard and mouse would locked up, the keyboard’s Caps Lock and Scroll Lock also flashed. The only recourse was to reset the computer.

Initially, I thought it was the power supply, then I thought the CD, DVD or floppy drives. I disabled the on-board sound. I even changed graphics cards. I should have tested the memory first. That was my gut feeling. I read on one of the forums that whenever there is a kernel panic that most likely, it would be a RAM issue. I should have done the memory test first.

The last couple days, I contemplated on buying a new motherboard, CPU and memory, but it can wait for now. Eventually, I need to upgrade.

Isolating the problem was great. It was an issue I have been battling for almost two weeks. Stupid me.

Currently, Frys sells 1GB DDR PC3200 400Mhz memory for $30. That’s the cheapest DDR without any rebates. I hate rebates.

I should really upgrade my system. I was looking at a package deal, an AMD Atlon X2 Quad 620 for $99, an Asus motherboard for only $40 at the Micro Center. It’s really a great deal. Throw in a 2GB DDR2 800Mhz RAM at $49 and I’m set to go, but I’ll wait for a little bit.

Hardware Issues

My Linux desktop is sick. It’s having a hardware problem. It’s causing the kernel to panic. The mouse freezes and keyboard is flashing. At times, it causes the OS to shutdown. It doesn’t matter what distro I install. I tried the last 4 Ubuntu releases, Linux Mint 7, Linux Mint 8 and Fedora 12. I haven’t figured out yet if it’s a memory or a motherboard problem. I have eliminated just about everything else including power supply, CD, DVD, sound card and graphics card. It’s probably a memory issue. So now, I’m stuck on a Windows XP machine.

Interesting news today. The French and German government are sending out warnings to those who use IE as the fallout of the Google and China IE Zero Day security hack reverberates worldwide. Microsoft is directing users to use IE 8 instead. I say move to either Firefox, Safari or Chrome. I abandoned IE 5 years ago for the same reason. Some call for dumping IE now.

If you contemplating in interviewing with Google, better Google about what Google could possibly ask you during the interview, because Google, the company, tend to ask very tough interview questions. It’s interesting to hear about Google’s hiring policy, in that it focuses on super bright, intelligent people, which doesn’t seem to always translate to the best workers or workers with great interpersonal skills or better yet, workers with common sense.

Should Fedora release Fedora 13? For superstitious folks, thirteen is an unlucky number. Nevertheless, Fedora is forging ahead. Fedora 13 benchmarks are out, along with Ubuntu 10.04.
