I discovered that DPMS fails when I boot an instance of android emulator, which is a 32bit app in my 64bit ubuntu. After clicking start->launch on the emulator, g-p-m starts to print the error when the screen timeout occurs, and even after exiting from the emulator this problem remains. Restarting g-p-m does not help. The only way to solve this is to run 'xset dpms force off' and g-p-m will automatically recover itself.
