I've upgraded the old computer to slackware current, I only had one problem which was quickly resolved. The upgrade took quite some time, probably because this computer only has a 2ghz dual core celeron cpu and is well over 10 years old.

It might just be my imagination but kde seems way more responsive with slackware current. Now after compiling and reinstalling some packages. I installed the greenpak software again and I get to the launcher but I'm missing dependencies to go further.

After compiling and installing another needed dependency, I finally got the software running but the project time for today is over, so I have to continue an other day.

Merry Christmas!
