I have been in love with Ubuntu Desktop for its polished user friendlyness and it motivated me to take a look at its server edition. I googled a bit about what kind of reviews Ubuntu Server gets nowadays but other than Ubuntu’s breif survey there are only debates about whether Debian is better or Ubuntu is better. I personally do not think there is an absolute answer for this debate because they both have its strengths and weaknesses. Anyhow I thought it would be interesting to try Ubuntu Server myself.
As soon as I upgraded my laptop’s Ubuntu 8.10 to 9.04, I started looking for what new features there were. I found one that was interestingly named. “Computer Janitor” Hmm…
It turns out to be something that I have been waiting for a long time. It scans all unused files including packages, configuration files and it even makes recommendations. When I ran it for the first time it scanned some of the old kernels. Curiously I selected all of them and started cleaning, and viola!! Next time I booted, all my previous kernel options from grub are all gone.
I have been trying out various OSes in Hyper-V environment but one thing that I am noticing is its slow installation process. Even installling Windows guest OSes takes a long time. However, once intergration service is installed on Windows guest OSes, performance improves.
However, linux in Hyper-V is out of question yet. I tried to install 32, 64 bit Debian, Ubuntu Desktop/Server but Debian is the only distribution that I was able to be patient enough to complete the installation. Debian base installation without GUI took a couple hours, where text frame buffer was horrible, almost unbareable, I had to wait about 10 seconds for each page to come up. All other distributions, I waited about a couple hours too but it did not even get into the installation screen so I gave up.
I have been a big fan for Remote Desktop in Windows XP/Server/Vista platform because you get a native display resolution of your client monitor and file/printer share is supported; however, for Windows 2000 or linux distributions, I do not have the option. There is an alternate option for Windows 2000 or linux distribution which is VNC.
For Windows platform, it looks like RealVNC and UltraVNC are the most popular ones while linux has many different VNC servers.
In this example, I would like to introduce a way to enable a built-in Vino VNC server for Ubuntu distribution.
I have a very powerful XPS 600 from Dell and I still love it very much. However, I had only one complaint which is its VT capapility switch in BIOS. CPU has VT capability but BIOS does not offer VT enable switch in BIOS. I have contacted Dell a few times before but it does not seem that it will be supported. So I started looking for a way to get around it.
The following information is what I found online. The feature control Machine Specific Register (MSR) for VT has two bits. The first bit is a lock bit and the second bit is a on and off bit. If the lock bit is locked then you do not really have a choice. However, if the lock bit is clear then you can enable the second bit from OS temporarily.
