hi,
I want to know that how can i upgrade my existing KDE desktop to a newer KDE version on the same linux distribution without installing a new linux distribution.
Please help me.

Sam.

Please provide as much detail as possible so that people can help you out e.g. the Linux distribution are you using.

hi,
I am using PCQLinux 2004 right now. Earlier i replaced PCQLinux 2004 with PCQLinux 2006. With PCQLinux 2004 my system was running really fast with most of the services running. but after instaling PCQLinux 2006 it became really slow. I stopped almost all the unneccessary services but still it was running slow. I got some other problems too like system-config-package failed (I think due to HAL daemon service as this service failed to start on startup), sound card was not working, etc. So i switched back to PCQLinux 2004 but i want to keep the KDE desktop of PCQLinux 2006.
(System Configuration : Pentium III, 128 RAM.)

Unfortunately I have never used PCQLinux so can't help you. It doesn't seem to be a popular distro and I can't find much info about it.

I did manage to find something saying it uses synaptic, so if you can get the newest .deb file from the kde site, you should be able to install that. I'm not really an expert with this kind of package since I quit using ubuntu a while back, but I know you can install .deb files with the command dpkg -i [package file name]. I'm not sure if there's another command specific for upgrading an already installed package though.

You also might be able to get it by enabling a repository with newer packages. If PCQLinux is compatible with debian, you should be able to use a general repository. But I know ubuntu does some things to packages which supposedly make it not completly compatible, so the same may be the case with this, so I'd be real careful about doing something like that unless you know it's compatible.

Just out of curiousity, I'm wondering why you're using this distro? I'm not even seeing it on distrowatch, which I thought had most distros on it.

This distribution came with the PCQuest Magazine. They release it every year. I am using PCQLinux 2004 for the last 2 years and found it great. They provide wide range of softwares and games. PCQLinux 2004 and 2006 are based on Redhat 9 and Fedora Core 3. They use rpm package manager.
By the way, Thanks for your help but I don't think I am gona install PCQLinux 2006 again. Its a very hectic task to install an OS.
Recently i heared about the release of Fedora Core 5. I ordered for the CDs and will try it as soon as i get it.
Thanks,
Sam.

If it's using rpm than you can probably try upgrading with rpms from kde, though it's probably not worth it if you're planning on switching to fedora anyway.

Though I didn't notice the last line of your second post before. With that kind of hardware, the slowdown was probably due more to the requirements of newer software. KDE by itself can be kind of RAM heavy. You might want to look into using a ligher environment. Personally I prefer XFCE or fluxbox, even on my new computer, and both of these use less resources than KDE
