Binary package hint: xserver-xorg-video-ati
Using freshly updated Jaunty.
Radeon driver generates more interrupts during screenblanks ('xset dpms force off') than not.
Measuring with powertop 1.11 my hardware generates approx 10 wakeups/s .
When issuing the 'xset dpms force off' wakeups increases to approx 60/s.
This seems to be radeon driver generating vblank interrupts during dpms off. Thus preventing the CPU to enter C3-C4 state.
=> increased powerconsumption during dpms!
Using repos opensource radeon driver.
Hardware: Thinkpad T42, Radeon 7500. |
