I'm running a dm4-1253cl, dual boot Win7/Kubuntu 11.04 and it does the same thing. The only way "out" (because the keys, mouse, etc. don't work) is to hold the power button down till it shuts down. Then I get a black screen when I reboot (always get a black screen anyway until I press the dedicated screen brightening button - which doesn't work on the aforementioned reboot). The only way to get it(kubuntu) running again is to boot into Windows and press the wifi button to on, then reboot into kubuntu.
