2009-04-21 14:14:07 Johannes Hessellund description 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.
