Uh... guys... I guess this is no longer a bug now... because I have just found the cause of the problem in the /var/log/pm-suspend (I get to know the existence of this log file in another bug):
/usr/lib/pm-utils/sleep.d/00powersave suspend suspend: success. /usr/lib/pm-utils/sleep.d/01PulseAudio suspend suspend: sudo: pacmd: command not found sudo: pacmd: command not found Returned exit code 1. 二 1月 19 22:08:08 CST 2010: Inhibit found, will not perform suspend So I had installed PulseAudio, but it lacks auxiliary tools to help it get suspended, so the suspension process of the system failed repeatedly. So I have just installed the pulseaudio-util package, which includes the pacmd command, so now I can suspend my laptop through KDE's Powerdevil applet. However, Fn+F1 is still not working. I hope I can find the answer soon.
