I still can't believe it. I'm back. I spent a lot of hours and it is still not perfect.
Let me explain what I did after the crash of my operating system openSUSE 10.3 which is Linux one.
I use an old IBM R50 with just 512 MB Ram which means it is not the fastest but good enough to communicate with the "world".
I did not want to install the same version of the operating again because because there are some limits but I still wanted to use Linux.
Fortunately we have a second PC. I decided to download an image (4.7 GB) of the latest openSUSE version 11.3. It took nearly three hours due to our bandwith.
During the download I read a lot of information about the new version (new desktop environments, new functions, new menus and so on) in order to get an understanding. Beside KDE and GNOME a third one - LXDE - is offered for installation. LXDE aroused my interest because it is especially designed for older PC, new generation netbooks and other small computers.
To burn the image on a DVD was not a problem.
Installation took a while because I struggled a bit with the partitioning of the hard disk.
Then next hurdle has been the connection to our wlan. But to my surprise I managed it after two hours.
So I'm back with basic functions. In the following days I have to restore my data, finalize the setting of firefox and install additional programs.
In the end I'm happy with the LXDE desktop environment and openSUSE 11.3. It is really fast and lean. It fits perfectly for my purposes.
And this is a screenshot of my new lean desktop
