It's been a while since I've been on FreeBSD, and I am thinking about putting it on the laptop I have now, but I really like my backlit keyboard and I don't want to lose that functionality. I searched the laptop compatibility page but mine isn't there and I'm not sure how to go about knowing whether it will work or not. It is a Dell Latitude E5520. A quite nice laptop. There is a similar lower end model that is supported by FreeBSD, but I didn't find any info about whether it has a backlit keyboard or not and if it is enabled. I noticed there is something about acpi settings to modify depending on what kind of hardware it is, but I am not sure how to find what kind I have. All I see in my system settings is that it is Microsoft ACPI compliant, but no other specifics. I have to hold the Fn key and press the right arrow to control it, so presumably it uses some software to control. Preferably I would like to know the solution before I install and try to figure it out, only to find it doesn't work. Namaste.
