Little-bit more details. The keys work, GUI changes and the value in /sys/class/backlight/toshiba/brightness changes from 0 to 7 when changing brightness, however there is no real effect on screen brightness. There is also /sys/class/backlight/intel_backlight/brightness file, which is not affected when changing backlight.

Data about my laptop:

sudo s2ram -n
Machine unknown
This machine can be identified by:
    sys_vendor = "TOSHIBA"
    sys_product = "Satellite R630"
    sys_version = "PT31LE-01600LG3"
    bios_version = "Version 1.50 "

There seems to be a similar bug:
