how to change brightness on toshiba laptop

I could not set volume on audio-0 (no controls), but could see volume controls for audio-1.

yast-sound reports 2 audio boards: ATI and AMD one is audio-0 the other audio-1. (some) function keys not working - including those which control brightness

web camera not recognized (seems it's a Chicony, although reported as Toshiba) touchpad (Elantech) not recognized - some threads say it's fixed in kernel 3.11 Personally I have a Satellite M50D-A-10Z for a couple of days now, and I'm facing the following: IMO AMD A6 APU are poorely supported in SuSE linux. Inquiring the system as to the CPUstep changes and setting could be helpful to understand/document the problem. Manual, webpages, etc are acceptable references I am willing to read and test options- at this point most documentation I have seen is for the wrong version in terms of OpenSuSE 12.3 (ie 11.x) and I have a feeling the desktop manager has an impact on dealing with those settings - potentially different choices for KDE, Gnome, etc. By this I believe the stated maximum can be exceeded for a period of time as recommended by the manufacturer but at some point for some reason should be reversed - ie too much heat generation disabling the turbo mode until the excess heat dissipates. Should a 'turbo mode' cpu like mine recognize the turbo operation level (seems somewhat like overclocked) to be a mode to be more aggressive in terms of either dropping out of or not engaging when powersaving is desired - possibly turned off when operating on a battery? Turbo mode in the case of the AMD processor is running in excess of the stated maximum for this processor. Even with automatic stepping control of the CPU would the possibility of aggressive up-stepping, aggressive down-stepping and a balanced approach be reasonable possibilities. Keeping the laptop cooler when editing files with the unit is on you lap is another reason - I have had the fan full on with heat spewing when gediting a text file on battery power that one would not casually believe to be a CPU intensive task. If running a task at night low power and longer execution can minimize fan noise (quieter for sleeping in a hotel room) as just one example. I read the powersaving description for 11.x about automatic controls instead of manual controls and I do not find the arguments totally persuasive. The brightness keys work the brightness control panel works but neither set values that are maintained across a poweroff-reboot? Is there some way to set the initial brightness to something other than full on? MY CPU seems to be in stepped up mode when relatively inactive. PS I believe the pertinent system specifications are in the title.
