One of the joys of using Ubuntu is the ability to easily customize even the most obscure features of the operating system and the login screen included with the default GDM theme is no exception. As with most light Linux tweaks, this one is quite straight-forward.
There is a utility included with Ubuntu that allows quick and easy customization of options within the GDM theme titled gdmsetup; you can run this utility directly from the main menu by looking under System -> Admin -> Login Window.
You’ll need to enter your admin password to gain access, then click on the tab labeled “Local” to see theme options. Under the section labelled “Style” you can select one of three main presets: Plain, Themed or Face Browser. Select “Themed” to gain the ability to select any graphic you like from the provided list along with several other default GNOME themes that may suit your fancy – customization is always great but you have to admit that the default GDM theme is a pretty attractive piece!
A Slight Flaw with the Debian Installer
A few weeks ago, I noticed some really good e-Bay deals on used, Opteron-based servers. I mean, they were going for less money than I had to pay for old Pentium III-based servers just three years ago. So, I decided that maybe it was time to upgrade.
Three of the four machines that I bought were Sun Sunfires, each with a pair of single-core 2.4 Gigahertz Opterons and a pair of hot-swappable SCSI hard drives. Since the drives are rather smallish, I figured I’d just combine each pair into one large logical volume.
On the first machine, I installed Fedora 11. When I got to the hard drive setup page, I chose to go with the default Logical Volume Manager setup. The installer then asked me how many drives that I would like to use for the Fedora installation. I chose both drives, and both were automatically added to the logical volume. No muss, no fuss, and everything worked fine. This is typical of the Red Hat-type installers.
On the next machine, I decided to install Debian 5.0. Again, I decided that I wanted to combine both drives into one large logical volume. When I got to the hard drive setup page, I chose the “Guided” option for setting up the LVM. The next page asked me which drive I’d like to use for the installation. I wanted to choose both drives, but Debian doesn’t provide that option. So, I backed out, and decided to use the “Manual” option for setting up the hard drives myself. That didn’t work either, because the “Guided” option had already created the LVM volume group. (That happened, even though I hadn’t been asked to confirm whether to write changes to the hard drive.) So, I backed out again, and choose to open a command-line session. I then used the LVM tools to delete the volume group and physical volumes. I then decided to go “old-school”, and try setting things up with fdisk and the command-line LVM tools. That way, I could get both drives added to the logical volume and continue the installation.
Only one problem. . .
When I finished, I went back to the hard drive setup page, thinking that my new, manually-configured setup would be recognized, and I’d be good-to-go.
Wrong. . .
Instead, my configuration got wiped out, and I ended up with the original single-drive setup.
Okay, no problem. I figured that I’d just continue the installation, and add the second drive to the logical volume later.
Wrong, again. . .
When the installation completed and I tried to boot from the hard drive, I got an error message about how the logical volume couldn’t be found. Apparently, the LVM metadata got messed up when the installer replaced my manual configuration. So, not wanting to waste any more time on this machine, I grabbed my Fedora 11 CD and installed it, instead. Again, no muss, no fuss. It automatically deleted my mess-ups and created the two-drive logical volume.
On the final machine, I gave Debian another try. This time, I just accepted the default single-drive logical volume, and continued the installation. After the installation completed and I had it booted from the hard drive for the first time, I added the second drive to the logical volume. I didn’t want to mess around trying to learn any graphical LVM utilities, so I just did everything “old-school”. (That is, I used fdisk, the command-line LVM tools, and the command-line filesystem resize tool.) Finally, I did a quick “df -h” to verify that the logical volume was resized correctly.
To be fair, I’m sure that Debian isn’t the only distro that has this kind of installer deficiency. And granted, for an experienced Linux user, it’s no huge deal to add a hard drive to the logical volume after the Debian installation has completed. Still though, you have to wonder. . .
If Red Hat can create an installer with an easy-to-use LVM setup, why can’t everyone else?

Update: I discovered some nice Linux netbooks last year while writing this article, Black Friday 2010 is all about Linux-based tablets and that’s what I’m shopping for. Check out my latest post Black Friday 2010 Tablet Deals. I’ve listed my favorite tablets launching on or close to Black Friday along with their specs and price tag.
Every year in the US, the Friday after Thanksgiving shoppers get up early and squeeze into stores everywhere to save a few bucks on holiday purchases. While saving money on new Linux Netbooks appeals to most Linux geeks, crowds of people and checkout lines often do not. Here’s two options for the geek who wants to get in and get out while still getting a great deal on a new Linux Netbook or laptop.
First of all, if you don’t need to buy a laptop or Netbook with Linux pre-installed you can find a large selection of Black Friday Netbook specials over at ZDNet. Many of these make excellent candidates for installing lightweight distros like Xubuntu, Puppy, and Vector after you purchase them. My personal favorite is the Acer Aspire One Netbook with a 10’1″ screen, 1GB RAM, and a 160GB hard drive for $149 in Office Max stores the morning of November 27th.
If you’re looking to find a discounted Netbook with Linux installed your best bet may be the Dell Vostro A90 Netbook which has been released as the “The Ideal Mobile Business Internet Companion” providing an excellent solution for lightweight computing on the go. Best of all this Dell Netbook comes pre-installed with Ubuntu 8.04.

The Ubuntu ShipIt Program. If you’re not familiar with it, you’ve probably never typed in “free Ubuntu CD” on Google or any other search engine. ShipIt is the Ubuntu service that gives away free Ubuntu installation CDs in an effort to make sure people have few restrictions obtaining Ubuntu. ShipIt has been a huge success shipping millions of free Ubuntu CDs over the past few years. The CDs are not free for Canonical, the company backing Ubuntu and the ShipIt program. This has caused Ubuntu to deploy some interesting techniques designed to cut the cost or need or the Free Ubuntu installation CDs.
Limiting Free Ubuntu CDs for people who:
-Can upgrade to the new release without a CD
-Can download their own CD for free
Ubuntu users can also:
-Download the CD wallet artwork
-Become an Ubuntu member by contributing to Ubuntu, making them eligible for more CDs

Requesting a free CD from the Ubuntu ShipIt program will take at least 4-6 weeks. For a more dependable solution order Ubuntu on CD or USB US Priority Mail now. Ubuntu training is available in video and course form.
