So I managed to have the touchscreen rotated, using xinput set-prop pointer:'ELAN901C:00 04F3:2Bd6' 'Coordinate Transformation Matrix' 0 1 0 -1 0 1 0 0 1 questions: 1) how do I make this setting permanent, so that it is applied again after a fresh boot? I've read to make a file like "50-touchscreen.conf" in /etc/X11/xorg.conf.d/ but obviously I used a wrong syntax as I could not login to the graphical system anymore after reboot. If this is the way to go, can anybody point me to the correct syntax, or tell me the correct way to make this setting permanent, please? 2) The Icon-Starters on the Desktop usually do not react (the don't get marked nor start the desired app). All the other things work (I can move windows, mark text, touch things in dolphin, firefox etc.). However in one exception desktop-icon-touch works: When I first touch an open window, and after that touch an icon, it works (app starts) as it should. But /only/ if I first touch an open window, and only once, directly after touching that window. Any ideas?
