Brightness flickering on Wacom MobileStudio
Submitted by Jehan
I just installed Fedora 26 (GNOME 3.26) on a Wacom MobileStudio Pro 13" computer, with a Intel® Iris™ Graphics 550 graphics card. The screen brightness is just going up, down, up down. Completely random.
Checking for instance in a TTY terminal, it looks like I see no brightness change. So my current assumption is that it is GNOME-related (and not for instance the video card driver).
Any data you need to diagnose?
