A strange problem...

Having decided that the benefits of desktop effects were outweighed by the disadvantages, I decided to disable them.

But without desktop effects, I no longer get a logout dialogue when I right-click on the desktop and select "Leave". The session manager settings are set to "confirm logout" and "offer shutdown options", which is correct for what I want.

If I fire up Compiz, or enable desktop effects in System Settings, the dialogue appears after selecting "leave", but if I don't, the only thing that happens is that the background fades (as I'd expect) but no dialogue appears.

Any ideas gratefully received.

UPDATE: still haven't fixed it, but I've managed to narrow it down to something in my user config. If I create a completely new user, the logout dialogue appears OK under it.

Now if I can just work out what's got mis-configured I might have a chance...

For info if anybody else has this problem, I got an answer from Ubuntu forums - delete ~/.kde/share/config/plasmarc and the logout dialogue reappeared.

The only noticeable side-effect was to revert the theme to the default. Not particularly worrying...

Update. Having removed the plasmarc file and then setting up my desktop to use the theme it was using before, I didn't initially notice any problem. Because of course, the dialogue isn't affected by the theme until the next time I log in (evidently it just changes the appearance, not anything else). So as soon as I logged in again with the new theme, the logout dialogue had again vanished.

So somewhere, there's a nasty bug with the ionized air theme.
