Stuff that could make you say WTF!
Network Time Protocol (NTP) is one of those services I like to use. The system uses it to sync with NTP servers on the Internet. Basically, it enables the computer to keep accurate time, and If my computer is connected to the Internet, I like it to keep accurate time, all the time. The Ubuntu installer uses NTP to set the time during installation. After installation, however, NTP is not even installed. I think that every computer should have NTP installed and running. If you are with me on this and you need to install and enable it, you can view the instructions here.
If you are trying to install Ubuntu 10.04 desktop on a hard drive that has an existing Linux distribution, that is, if you are trying to setup a dual-boot system, and if the existing distro was installed using an LVM (Linux Logical Volume Manager) disk partitioning scheme, the Ubuntu installer cannot “see” it. In the image below, for example, the Ubuntu installer reports that “This computer has no operating system on it.” However, if you look closely, you will notice that two partitions already exist on the computer. The first one, /dev/sda1, is the boot partition, and the second, /dev/sda2, is the unencrypted physical volume of a Sabayon 5.2 installation.
This is what happened when I tried to manually partition the disk. The installer clearly shows that /dev/sda1 has an existing ext4 filesystem, which is actually the boot partition of the Sabayon 5.2 installation. As reported earlier, /dev/sda2, which the installer could not determine the Type, is an unencrypted physical volume of an LVM-based Sabayon 5.2 installation. If faced with a similar situation, your best solution would be to first install Ubuntu, then the other distribution.
If you are as paranoid as I am, you probably like to encrypt your hard drives. Not just encrypting one or two partitions, but the whole drive. Unfortunately, the Ubuntu desktop installer lacks support for full disk encryption. The best it does with regards to encryption is provide an option to encrypt your home folder. In terms of enhancing the physical security profile of your Ubuntu installation, this option actually does very little. As far as I’m concerned, it’s useless. It is a sloppy implementation of (disk) encryption. For an excellent example of how disk encryption should be implemented, read how Fedora protects your computer with full disk encryption.
Assuming that you opted to encrypt your home folder, the system will present this informational window to you when you first boot into your newly installed Lucid Lynx desktop. So you say, why not, I’ll “Run this action now.”
This is what happens when you click on the “Run this action now” button. You will need to print or write down that 32-character passphrase, and store it in a safe location (hopefully, you’ll remember where when you need to use it). Like I wrote earlier, this is sloppy.
Why is ufw not running and why is a graphical firewall client not installed? ufw is Ubuntu’s user-friendly command line interface to the firewall application built into the Linux kernel. Out of the box, the ufw service is not started. And Gufw, the graphical interface to ufw, is not even installed. It’s either that the folks at Ubuntu think that you don’t need to run a firewall on their distro, or they just want you to give you something extra to do.
Here’s where I stand on this: You need to have an active firewall on your system. And that applies whether there are open ports or not. And to make it easier to manage the firewall, you need to have a graphical firewall client installed. You can find instructions on how to install and enable a graphical firewall client on Ubuntu here.
Dude, what happened to the title bar? The title bar is that section of a window which sits atop the menu bar. You can see it in the image below. In the course of writing this review, it just disappeared.
Here’s the same window without the title bar. Where did it go. I sure did not do anything to cause it to pull a houdini on me. In any case, rebooting brought it back from where ever it went. Has anybody else experienced this?
And why does the screen resolution keep changing? My test monitor is an LG FLATRON M237WD. The highest resolution available is 1920×1080 and the lowest 640×480. The available refresh rates are 75Hz and 60Hz. But that’s when everything is working as intended.
Sometimes the screen resolution changes automatically such that the available screen resolutions are the ones shown in the image below, with a lone refresh rate of 60Hz. What that does is shift the viewport to the left, leaving a black, one inch margin to the right side of the display. Logging out and then back in does not fix it, only a restart does.
