Public bug reported: Binary package hint: xserver-xorg-video-ati
I am using a laptop with a radeon X1600 graphic card. To reduce heat and increase battery life, I would like to reduce the frequency of the GPU and graphic RAM. With Ubuntu up to intrepid I was using the fglrx driver and could do what I want. Since jaunty I am using the xserver-xorg-video-radeon driver. In karmic a new driver option appeared: Option "DynamicPM" "boolean" Enable dynamic power mode switching. This can help reduce heat and increase battery life by reducing power usage when the system is idle (DPMS active). The default is off. Unfortunately, when I activate it, the X server uses 100% CPU (but seems to work well otherwise). I tried "strace -p PID_OF_THE_X_SERVER" to know what the X server is doing with the CPU, but the X server locked up.
