Thank you very for your answer.
For me it was especially interesting that you used LMDE Cinnamon on an x230. I am writing the message on an x230 but still with MS XP.
I making tests with an ancient x40 and LMDE MATE (a hint from the LM forum) runs nicely. I only had a bit of problem with the track pointer (viewtopic.php?f=191&t=167893
) but could solve it. For the newer PCs I consider to use LMDE Cinnamon. With your information I do not expect problems on the trackpointer-trackpad unit of my x230 and x240.
You do not have accidentally experience with switching between English/German and Japanese using Linux? This is currently my big problem: viewtopic.php?f=199&t=167661
