Hello everybody!
I wish to install openSUSE but with a special desktop environment. I wish my openSUSE to look completely the same as, or very similar to, the old-fashioned openSUSE desktop with the big Geeko start menu button and the home icon, old KDE trash, My PC icon, etc.
Is there any plugin to do this? Can I do it with modern KDE Plasma, or do you recommend using the Trinity Desktop to modify it?
Here is an few example of how exactly I want my openSUSE to look:
Thank you!
I would like it to know too, how to doing this KDE 3.x using into today’s SUSE and OpenSUSE .
Maybe:
https://en.opensuse.org/KDE3
But I do not know, if it works.
It is on you to test it.
Thank you for the comment. Well, I’ve thought about this, but I’m not sure whether KDE 3 can still be used safely nowadays. It may be outdated and could have bugs that can be exploited by hackers. Although maybe I’m wrong about this. Trinity or modern KDE Plasma would be a safer choice to modify.
I’ve never stopped using it as my main DE (still using 15.6):
However, I’ve been unable to locate that particular icon on disk in any icon tree. Closest I could come:
# lsof | grep icon | grep -vE 'monk|hrom|efox|moon'
kded 1312 moz mem REG 259,8 65696 398227 /opt/kde3/lib64/kde3/kded_favicons.so

I liked KDE 3 a lot at its time. But that’s at least 15 years ago, probably even 20 years. But there is this:

We might all burn in hell for even mentioning it, though. 
Roughly half my openSUSE installations have only IceWM and TDE installed, using TDM, same as all my Debian, Mageia and Ubuntu installations, and most Fedora. I’m even using TDM and TDE on Neon. What ain’t broke don’t need fixin, didn’t in 2008-01 (KDE4), doesn’t now, so still KDE3 on my 24/7 15.6.
Thank you for the answers I am going to try out the old KDE 3 and Trinity. Although it would be greet if somehow I or someone else can extract the assets from the KDE 3.5 (big green geco icon, house icon etc.) and implement them directly into Trinity or modern KDE plasma.
Plasma is highly customizable. You will for sure find a theme or icon set which looks like from a century ago. Most users prefer to have a fresh and modern look. But the few users which want to have the ancient look can customize it on their own. Have a look at systemsettings. You can download themes and icons and more.
Thank you!! 
I am going to check out sooner or latter when I installed again OpenSuse in the near future!
I’m using Trinity (i.e., TDE) for a few days now and I’m liking it. There are some minor things, such as a sound error message upon login but my sound works perfectly fine, and multi monitor support isn’t the best, but they are those “I’ll get to them when I get to them” sort of things.
I am in a similar boat. I tried KDE Plasma and LXQt, but I’m more of a fan of the desktop metaphor in the 2000s, and this is really working for me so far.
