Here's what I would try.
Code:
cd /etc/X11
mv xorg.conf xorg.conf.bak
aticonfig --adapter=1,0 --initial
Code:
cd /etc/X11
mv xorg.conf xorg.conf.bak
aticonfig --adapter=1,0 --initial
I had a look at the BIOS and I couldn't find any option relating to the graphic card.
It seems that I am only able to use the 4200 GPU, it is listed as the default adapter and it bears all the load:
Code:
amdconfig --lsa * 0. 01:05.0 ATI Mobility Radeon HD 4200 Series 1. 02:00.0 AMD Radeon HD 6300M Series * - Default adapter
Code:
aticonfig --odgc --adapter=all Adapter 0 - ATI Mobility Radeon HD 4200 Series Core (MHz) Memory (MHz) Current Clocks : 203 400 Current Peak : 500 400 Configurable Peak Range : [200-500] [400-400] GPU load : 18% Adapter 1 - AMD Radeon HD 6300M Series Core (MHz) Memory (MHz) Current Clocks : 750 800 Current Peak : 750 800 Configurable Peak Range : [400-750] [500-800] GPU load : 0%
Thanks for all the help
