I have a new laptop and currently screen brightness isnt working. Having studied the dmesg logs and poking around the kernel sources I have an idea how to get things functional, but I’m struggling with getting a kernel dev environment on Fedora Silverblue working and I find the documentation a bit lacking.
Looking at the docs I can check out the kernel sources and start a build with fedpkg local, but its not clear to me what I’m actually building. My workstation computer with Ryzen 9 and 32 GB of RAM and a PCI 5 NVME has been blasting away for 30 minutes and is still not done. A vanilla kernel build usually takes significantly less time to compile. Is it building a plethora of flavors? And is there a way to edit and apply kernel source changes without having to make and apply patches? The docs suggestions running fedpkg sources, and this downloads xz files with the sources. I presume I should just extract this in the current directory and edit the sources there?
Thanks!
