This wasn't needed with the old powerlib method because it used to create a new connection on every call, which was suboptimal either. I don't think that a mainloop where we listen for signals is something we want to have at this point in kicker, startmenu or ksmserver, right? If, so I would close this as WONTFIX because we have no way to do this with the current lack of D-Bus support for KDE 3.x. And it's definitely no blocker just because you can't suspend via the KDE menu. You still have kpowersave and a dbus restart should be also _very_ rare. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.

What liblazy call is needed to do that? -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.

This would also solve 222207 and allow lock screen, execute e.g unmount etc. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.

But in future we might depend on a policy manager, whether that's kpowersave or in KDE core doesn't matter. Nevertheless, Danny mentioned the "call HAL after trying with kpowersave" as a fallback. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.

You just have to add one additional line before using any of other functions of liblazy. But please take care about the warning ;-) /** @brief use a private connection for system bus messages * * Call this function with a boolean value to tell the library whether to * use a private connection for system bus messages * (liblazy_dbus_system*). Defaults to false. If a private connection is * used, the libarary creates a new connection on _every_ call and * immediately closes it. So this should be used very carefully. Only use * if your application does very rare dbus calls and doesn't have a * mainloop to listen if D-Bus died but still should be able to survive * D-Bus restarts. * * @param use_privat 1 if the library should use a private connection, 0 * otherwise */ void liblazy_dbus_system_use_private_connection(int use_private); Still, trying via DCOP first (or at all?)is the more proper solution. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.
