Event code 0 (?) Testing ... (interrupt to exit) The events are only reported if I suspend to RAM with "s2ram -f -p -s".= I did the following steps: 1. Execute "s2ram -f -p -s". Now the system suspends to RAM. 2. Push the LID switch and hold it down. 3. Wake the system with the POWER button. 4. After the system is up, release the LID switch to see the screen. 5. "evtest" reports the following line: Event: time 1219526119.163805, type 5 (?), code 0 (?), value 1 6. Execute "s2ram -f -p -s" again. 7. Wake the system with the POWER button. 8. "evtest" reports the following line: Event: time 1219526913.208803, type 5 (?), code 0 (?), value 0 M=E1rton N=E9meth -- To unsubscribe from this list: send the line "unsubscribe linux-acpi" i= n the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
