this graphic depicts KDE’s kernel system settings module, which lets you install or remove a kernel, but doesn’t have any option that I can see for choosing a kernel. the only option is to uninstall, but if you do, you lose packages that might be required for the system to boot. Who knows?
I want to change kernels, how do i do that? what is this widget even supposed to do? How is one supposed to keep their cool when faced with this sort of thing? This widget looks like a fast track to brick your system. I want to use the rt kernel. And not just for one little try, but permanently.
