    Desktop screen does not fill available area. Kubuntu 10.04LTS

    Have just installed Kubuntu 10.04LTS on an old Toshiba Tecra8200 (previously running Windows XP Pro):

    Processor: Intel Pentium III 1 GHz
    Installed Memory: 256 MB (SDRAM)
    Display: 14.1 in
    Hard Drive: 20 GB

    Installation went OK and runs as expected. Problem is, the desktop screen does not fit the available screen area. There's about a 3cm black border around the desktop.

    Have gone into the BIOS settings, have changed the 'display setting: 'LCD Display Stretch' to 'enabled'.

    Saved the changes to the system settings and confirmed this, but when the laptop reboots the problem remains.

    Any ideas?

    That computer's memory capacity is pretty low -- probably it's going to swap (I hope you made a swap partition).

    OK, to the point, in a terminal issue
    Code:
    lspci -v
    and let's see what the graphics chip is.

      Hi, thanks for getting back to me.

      Yes, could do with a bit more RAM, I've found the most it will take is 512MB. Looking to upgrade it to this, soon.

      No, didn't make a swap partition. Should I have? I'm pretty new to all this. (Saying that, I've been running Kubuntu for nearly two years now. Other machine is a:

      Toshiba Satellite Pro A120 laptop.
      2Ghz Processor
      2GB RAM
      HD 100GB

      It goes like a rocket in comparison! Still, getting the Tecra up and running is more of an experiment.

      So getting back to the swap partition, if it means a re-install no problem, it's all good practice!

      Still find command line 'baffling' but interesting, but anyway...

      Went into Terminal and entered lspci -v. The result is listed below:

        Well, there it is ... whatever it is. :P

        The tridentfb kernel module is not familiar to me, but probably the "fb" stands for framebuffer, which is usually not good news for the X server. Mr. Google found a little information about GPU, but it's ancient news:

        http://fixunix.com/portable/12172-re...rblade-xp.html

        The second link here: http://www.downloadsource.net/c146/Trident/

        says it is "for Linux". That's all I can find about this unusual graphics chip.

          Tridents are notoriously troublesome sometimes

          some starting points to get the correct resolution (I am guessing 1024x768)

          The gpu is old and poorly supported at best, but you should be able to get it with a little hacking

            Re: Desktop screen does not fill available area. Kubuntu 10.04LTS

            In addition to the above information .......yes you should have a swap partition on that box even if you put it up to 512 RAM .......I would give it at least 1 Gig .........

            On the display ........dose the monitor have any fine tuning adjustment's ?

            If it's just a small amount you may be able to use the hight and width adjustments on the monitor to fill the screen I had/have (I pack-rat every thing computer) a old box and monitor that I had to do that with

              Thank you dibl, claydoh and vinnywright for your advice. Will give it a go.

              Having now looked up what a 'swap partition' is, it sounds as if I'd be advised to create a swap partition first.

              Will creating a swap partition improve the speed of the laptop, regardless of the amount of RAM it has? (Whatever happens, I plan to increase the RAM anyway). Apologies if that is a dumb question, but still trying to get my head around it!

              So looks like a re-install for me, bit of a pain, but it's all a part of the learning curve I guess.

              Will get back to you, thanks again,

                I would not say a swap partition will make your computer faster; rather I would say a swap partition will keep your computer from falling to its knees and putting its little head on the chopping block, while running multiple applications that need access to the limited memory that is available.

                Assuming you are successful with the upgrade to 512MB of RAM, then you should probably make a swap partition of 600 - 700MB. That will allow it to swap out when needed, and if you don't push it too hard it might be usable.

                FYI, a lighter desktop like xfce or lxde would perform far better than KDE on this limited hardware platform.

                  I just had an annoying gap caused by fake Panels. Quitting and restarting plasma fixed it.
