New Life for an Old Laptop – an Update part 2

After gettng Fedora running successfully as I covered a couple of days ago I decided to see if I could improve it a bit. I know from previous experience that memory usage is probably more important to performance than many people realise. One of the easiest ways to improve performance no matter what type of computer or OS you have is to make more memory available. When I upgraded the memory on this laptop it felt like a new machine.

The first  thing I did has no direct impact on performance but if done carelessly can have a negative affect. I customised the appearance of the desktop. While trying out different themes I discovered some activate “Enable GUI Effects” under the effect tag of Style. This can have a detrimental affect as I discovered so I made sure that was off. I also changed the Background to use colour instead of an image. Choosing the wrong (ie. a large) image can make a big difference so I played it safe.

With the desktop looking better, to me anyway, I looked a bit deeper. I found this page of Fedora 8 services. There is details on earlier versions on the site as well as lots of useful  general Fedora info. All operating systems include a wide range of services which are small programs that run automatically and handle such things as networks, interaction with hardware and all that “behind the scenes” stuff we take for granted. While they are essential often there are some included that aren’t required. Eg. no need to have Bluetooth running if your computer can’t handle it or you don’t use it. Following the guide here I turned off quite a few services I don’t need. I didn’t do a comparision of memory usage before and after but there was a small improvement in speed.

Sites like this are available  for all Linux distros and are worth the effort. At least you will learn a little about how your system works. If you follow the advice here there is little chance of doing anything terminal to your system. At worst some piece of hardware may stop working. Just restart the service and it should be OK again.

New Life for an Old Laptop – an Update

I detailed in the original article how my Thinkpad T20 was given a new lease on life. With a small investment in hardware upgrades, memory and hard drive, plus a new operating system, Ubuntu 7.04, it was proving useful again. As so often happens with these projects they are never over. So here are some details of the current state of progress.

Time for an Upgrade.

Ubuntu has served me well on this machine and although Gnome is not my favourite desktop manager it was working ok. I was aware that it was an older version and would soon be two releases behind so it was time for an upgrade. The question was what with.

I had a copy of a version of Xubuntu (Ubuntu with the lightweight Xfce desktop) and being aware that it used less memory than Gnome thought it might be a good idea. It lasted a couple of days. Not that there was anything wrong with it. Everything appeared to work, wifi worked “out of the box” as I have come to expect from Ubuntu. It had a few strange things , eg. the splash screen wouldn’t resize to my screen so it was off centre. It didn’t affect operation as it was only there while it booted and then it was fine. But it didn’t “grab” me. Not very scientific I know but didn’t feel it was better than what I had previously.

So I decided to go in the opposite direction and install Fedora 8 with KDE. This is what I use on my desktop with all the bells and whistles, Compiz-Fusion etc. I knew that wouldn’t work on the old laptop but I wondered how a basic KDE installation would run. I have used KDE most of the time I have used Linux and it is still my preferred environment. I look forward to KDE 4 in Fedora 9 but that’s a story for another day.

Installation

I installed from a dvd copy I had on hand and all appeared to go well. I had the system running with the correct video set up without any of the tweaking needed in Ubuntu. One serious issue, no wifi. I connected up an ethernet cable and had the internet working that way and left it to do an update. In the meantime I did some research on the Fedora forums. As usual the answers were all there just need a little patience to sort through all the information.

With the update done I installed the madwifi driver from the Livna site following the information here. My Netgear WPN511 (Atheros chipset) was now recognised but couldn’t link to the router using wpa2. I turned on the NetworkManager and NetworkManagerDispatch services in System – Services and now after setting up the passphrase etc. it all worked.

The Result

I now have a usable Fedora 8 system on hardware I doubted would handle it. It is slower than the desktop of course but no slower than the Ubuntu system it replaced. It is used primarily as an internet terminal with occasional office document editing or photograph viewing. I wouldn’t like to do much photo editing on it but for everything else it works great.

There are still one issue to look into. The hard drive has a partition I use for archives. It has an ext3 Linux filesystem and Fedora recognises it but any attempt to mount it produces an error. I’ll look into it further when I get some more time.

Writing a Post

An idea for a post strikes and what do you do? If you are busy you may ignore it or forget it. What a loss that may be. The best article you ever could create gone forever. So is there a better way?

I prefer to make a note of the important points and get back to it later. I use a text editor, word processor or even a pen and paper, whatever is at hand. I have a text document that contains a few half written posts. That way when ever I add something new I can see the notes I made previously and it reminds me to do something with them. When I need something to post this is where I come looking for ideas.

Next step is to type out the details. I use the same document so all my ideas are together. I try to flesh out the notes I made into a readable piece. I don’t normally post it straight away. I leave it and come back and reread it. I make some changes if I think it needs it and then post it, maybe. Sometimes I edit a few times, occasionally it never gets posted. Only post when it is as good as you can get it.

Of course this doesn’t work with the latest news, that must be out immediately but most things are not as time sensitive.

Of course this isn’t a perfect system. Sometimes an article may sit here for a long time, maybe forever. There are times when I intend to post something open this document, edit a few articles and not post anything. But usually the final post is better than the original effort.

What do you think? How do you work, do you have a system?
