I have few Wacom tablets in my studio, and recently I started moving to KDE. Unfortunately there are few showstoppers with it on KDE.
1. First, no Settings app, one that worked on KD4 was doing gr8 but now on KDE5 we do not have app for that. So, I set my wacom with xsetwacom which is OK, I can live with that.
2. Second problem is more problematic, for some reason in Dolphin if I want to select few files by Shift Left-click it does not work. Works with mouse but not when I am using Wacom. It seems to me that every time I select file, if use Wacom, it deselect everything first.... Anyone can help with this?
