After updating the catalyst driver from the Vi0L0's repository (the one that's listed on the wiki) I found out that I can no longer adjust the brightness of the screen (even by writing to /sys/class/backlight...), I tried adding acpi_backlight=vendor to the kernel boot parameters, but it didn't help. I also tried installing the catalyst-total package from AUR, but that didn't do anything. Can anyone point me in the right direction how I can fix this?
EDIT: Noticed an interesting thing, after hibernation the brightness changes to previously set levels, I can't change it while the system is running.
