https://bbs.archlinux.org – Hey all. When I start up my machine, the brightness is at full intensity, but when I use the Fn keys to change it, the brightness drops way off and the screen is almost unreadable. The problem is exactly the same as this one.https://bugzilla.redhat.com/show_bug.cg … &id=677694When I go into /sys/class/backlight/nv_backlight/ , the max brightness is 1025 and the brightness is 1073864551.After I use the Fn keys, the brightness drops to 1025 and won't go any higher. Trying to change the brightness manually results in a bunch of errors even when I'm root.The solution posted is to u (HowTos)
