How to decrease the brightness in fedora 14 on Acer (model: aspire 4736). Even i am using Fn+left arrow but brightness never decreases .It appears same when the level of brightness at empty as well as at full.
I think it may depend upon the boot options and what options you selected when installed. I know that Ubuntu and RHEL both let me control the brightness on my Dell Laptop. . . . Yep. Just tested. I'm running Scientific Linux 6 on it now (an RHEL 6 clone), and the Fn-up/dn keys (what my system uses for brightness) works just fine.
