I am using Wacom Intuos Pro S on Ubuntu 20.04 Desktop. After startup I run some applications like Xournal++ where I use my pen to take handwritten notes. After booting my pen works finely. If I leave the computer unattended for some time and the screen is unlocked again, my pen does not work any more. How can I reactivate my digital pen without rebooting the computer? The terminal command "xsetwacom --list" returns:
Wacom Intuos Pro S Finger touch id: 12 type: TOUCH Wacom Intuos Pro S Pen stylus id: 10 type: STYLUS Wacom Intuos Pro S Pen eraser id: 11 type: ERASER Wacom Intuos Pro S Pen cursor id: 17 type: CURSOR Wacom Intuos Pro S Pad pad id: 18 type: PAD
The pen still seems to be recognized. How do I reactivate the digital pen so that I can use it again?
