Hi ,
I am using KDE as a default desktop in Red-hat 9.0. When i want to shutdown, every time i have to logout and then i have to shutdown .

Is there any shortcut for shutdown directly from KDE apart from using command ?

First, do you have acpid running (ps aux | grep acpid)? If not - launch it (add it to the list of launched services in /etc/rc.d/rc5.d by linking it from /etc/rc.d/init.d to /etc/rc.d/rc5.d/S44acpid ; if there isn't /etc/rc.d/init.d/acpid - try installing acpid). Second, do you have button kernel module loaded (lsmod | grep button). If not - add it to /etc/sysconfig/modules . Now you should try pressing shortly the power button. Your system should go down through init 0.

First of all i like to thank u for given the solution for clipboard problem.
For shutdown prob i do'nt have power button in my keyboard. so i can't implement ur solution . any other alternate solution ?

I meant ACPI power button on your computer, not keyboard power button (which must be exterminated).

Also try '/sbin/init 0' as root (after su from console, for example). If you dislike entering the password, you can just run visudo from root console, and try to apply man sudoers... something like
'<your login> ALL=(ALL) NOPASSWD:/sbin/init 0'
after that create a file somewhere on your Desktop, consisting of two lines: '#! /bin/sh' and 'sudo /sbin/init 0' . Then launc the file to shut down.

great tip raskin... even i faced this some time ago. but then switched from gdm to kdm, wherin it gave more options - 'logout, shutdown, reboot, cancel' as opposed to gdm which gave only 'logout, cancel'. [ parthiban.. you can try this by enterring preferred=kdm in /etc/X11/prefdm file... obviously if you have kdm installed ]
havn't tried the option you gave raskin... but doesn't that do a 'hardware shutdown' (as we are using the button on the cpu box).... as opposed to the 'software' shutdown that we do by pressing the shutdown button on screen ?

If you have ACPI MB, then ~5s push shuts down while <2s push just sends an event to os. Module button catches the event and feeds to /proc/acpi/event . acpid catches it from there and shuts down.
Well, first time you'd better try after 'su -c "/sbin/init 1; sync"' if you aren't sure.
