You have missed the best part: At the same time they are talking about ending feed-in compensation for renewables they also planning to disallow renewable upbuild without proper grid capacities while also removing any incentive for grid providers to build up the grid. Grid providers that are usually well-connected or subsidiaries of fossil-fuel heavy energy companies. And on top they reworked the guide lines for energy security in a way that disqualifies basically all storage and only allow fossil fuel power plants a a backup solution.
So exactly nobody will seriously invest in renewables again as any profits are now depending on a third party that benefits from you failing. And storage is once again dead (not surprisingly as the CEO of the worst offender in delaying applications for grid connections of batteries (literal years for a process that should take a few weeks) was awarded with a job as Minister of Economy and Energy).
The whole corrupt German government is basically running one big scam to make the country dependeable on fossil fuels forever while screaming 24/7 how green power is the reason for high consumer costs.


I don't know if Fedora (or plasma) do things differently but the normal default is that you need sudo to reboot/shutdown/etc.
Then on basically all distros using systemd this behavior is modified via logind session and polkit. So the first thing to look at would be if a shutdown rule exists in
/etc/polkit-1/rules.d/that allow users in a certain group to shutdown/reboot in the first place.Mine looks like this:
/etc/polkit-1/rules.d/50-shutdown.rulespolkit.addRule(function(action, subject) {if ((action.id == "shutdown" ||action.id == "reboot") &&subject.isInGroup("wheel")){return polkit.Result.YES;}});So every user in the wheel group can do it without password prompt. Without this UI elements for shutdown/reboot will try assuming they have the right but simply fail.
