Fedora 20 Cannot change display brightness/backlight on HP ProBook G3
I have recently started using Fedora 20 on an HP ProBook G3 laptop. Since my teammates are already using Fedora 20 on their PCs I had to go with it. I love working on Fedora, altho Gnome is a bit awkward coming from Ubuntu. Consider me as a beginner on linux. My problem is Im uanble to change the display or backlight brightness on the above laptop although it works fine when I boot into Windows 10. The slider to change brightness is not present and the Fn buttons are not working, when in Fedora 20. Given that I have to work on Fedora 20 without upgrading, how do I change the brightness level to a value I like in Fedora ?
thanks
Maybe look at some of these answers? https://ask.fedoraproject.org/en/ques...
Forgot to add. I tried the instructions on that link. But changing the kernel boot parameters didnt do anything.
Before you spend to much time fixing and tweaking your Fedora 20 installation, I'd recommend you upgrading to a supported release of Fedora, currently F27 and F28. Fedora 20 is End-of-Lifesince many years and not supported with critical security updates anymore. You can get Fedora 28 from here: https://getfedora.org/en/workstation/...
@florian, I'd luv to but my team is working on F20 and I dont want the binaries and libs to be inconsistent/incompatible. Actually I tried running F28 Live from a pen and it worked beautifully compared to F20. My question is, if linux is really open and can be tweaked any way you like, why not let me get this fixed with drivers/apps that I can find from the net. I mean wudnt it be just another recompile of code (for the drivers/apps) that works for F28 but on my laptop with F20 ? #juscurious
I think the gap between the technology of the machine and the older OS is to wide. Take a newer OS.
