Please do. There must be some problem in sonybright.sh if your backlight adjustment is not working from hotkeys, either it not being called, or its actions aren't being interpreted or the script itself is just wrong. Have you tried running
]~$ sudo /etc/init.d/acpid restart
After logging in to Ubuntu, then trying hotkeys again? This is necessary to make the script work as per bug #173652
