[Bug 310764] Re: kdm not possible to halt or reboot

[Harald Sitter]

Hey dmoyne,

It is unlikely that the problem is caused by any interaction of kdm and
compiz.

The KDE shutdown sequence looks basically like this:
* user invokes kde shutdown with certain type (logout, shutdown, reboot...)
* a part of KDE (called ksmserver) will then try to get all applications to quit properly (in order to store their session data), if they don't quit within a certain amount of time, it will try to kill them
* once all desktop processes have quit, ksmserver will pass the shutdown type to kdm (in case it needs kdm interaction, i.e. anything but logout)
* ksmserver ends the whole kde session and kdm takes over

So I presume that either compiz doesn't quit and/or doesn't take kindly
to killing and/or somehow compiz (as a window manager) would need
special treatment by ksmserver to get shutdown properly.

I am not sure on this, but compiz stopping the shutdown sequence seems
like the best option here. So I am bouncing this bug over to the compiz
package, maybe the specialists in compiz matters have a clue to what is
going on. Otherwise they can be free to bounce it back to us for
investigation on the KDE side.

Have a nice day, and thank you for this report :)
