I encountered a bug with the current version of libddcutil used in Debian 13
Trixie, the bug in question affects the power management settings of KDE
Plasma
of Laptop and desktop users, for example, battery indicator dissapears,
screen
brightness keys do not work and the impossibility to switch the system power
profile.
This occurs when the machine wakes up after suspension. Here are some logs.
This bug is already fixed upstream with the version 2.2.1
