‘suse linux10.2’ could be taken to mean openSUSE 10.2 or SUSE Linux Enterprise Desktop 10 SP2. The output of these commands
$ cat /etc/issue
$ cat /etc/*release*
should clarify which one you are using. If you’re using openSUSE you want the openSUSE forums.
Which one you’re using is a bit academic really though, because they both went End Of Life about 4-5 years ago and as such are no longer supported. If you’re new to Linux, start with a version of Linux which is actually supported. Using an old version is just setting yourself up for problems and people on forums telling you to update.
If you’re using SUSE Linux Enterprise Desktop 10 SP2 then you should update to SLED 10 SP4 which is the currently supported version of SLED 10, or better still update to SLED 11 SP2. If you’re using openSUSE, get the latest version of that.
splashy is included in SLED 11 SP2 and is installed by default but as far as I can tell it’s not included in SLED 10 SP4. splashy source can be obtained from the splashy project website https://alioth.debian.org/projects/splashy/
