if I don't use AMDOverdriveCtrl - I get the following message after passing `aticonfig --od-setclocks=985,285 --adapter=all`:
ERROR - Set clocks failed for Adapter 1 - ATI Radeon HD 5800 Series
Please check that input values were valid
So AMDOverdriveCtrl must be doing something...And it's not `aticonfig --od-enable --adapter=all` ... that didn't change anything.
It would be good to know how to script Screen anyway - for general Linux education.
