I am having problem with Ubuntu 13.10 brightness control. My brightness shortcut keys (Fn + F5/F6) worked in 12.10 and 13.04 but they have stopped working in 13.10.
I am using Sony Vaio SVE15113ENB with VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09). Any help is appreciated.
I have tried following options, but none of them has worked so far:
- Installing Additional Drivers from Software Centre
/etc/X11/Xorg.confile for editing but it does not exist for me.
- Visited Software & Updates > Additional Drivers tab, but it shows nothing saying 'No additional drivers available' and 'No proprietary drivers are in use'.
Thanks in advance for any help.
