Thanks Duncan. I'll have a read. That sys admin one could be very interesting. The system installs do change the windowmanager variable but I'd like more info on what goes on there.

I think I have managed to sort out what is going on since asking. I was particulary interested in start button menu's and taskbars. I can summarise the start button. Desktops have menu catagory trees whose contents may be set by a distro. The one on opensuse contains and amazing number of categories eg all will have utilities. It has history, science and miriads of others. Along side that there is a directory with dot dektop files which also contain category information. These seem to be scaned and and linked somehow into the eventual menu. There does seem to be user local taskbar set ups but also something system wide and as you mention some apps look after specific user settings in various ways. A few and the desktops seem to be doing that of ~/.configure. Seems like a good way forwards to me.

I started wondering what was going on when I installed lxde as a test to another user account. I expectd that to give some isolation. It didn't my kde menu was twice the size and full of lxde apps some of which can't even work on a kde desktop. I then looked at another kde user ;-) Root. Same there so there is no isolation even if all users use the same desktop. Something windows has coped with for a very long time. Different desktops is one of linux's advantages but not much of one if it works as it does. It's a mess and one kde users menu settings changing anothers isn't exactly good either. I mentioned this on a forum and it was blamed on window managers. I'd be surprised if that was true so became curious. Turns out it's due to where distro's put the desktop files and I suspect when I ask kde about this aspect they will suggest they should go some where else that is user local. There seems to be scope for both user local and machine wide installs but I'm not sure which user local
  directories over ride or add to the existing ones. It would be a right mess to sort out anyway every time an appliction or other desktop was installed. Ok this is on one machine but some do that.

:-) I feel like making some noise about it - if I'm totally correct, in the hope that it will be fixed. So sorry about the long post. Most problems seem to be at the distro end.

SDDM may have a problem as well. It looks like it could log into a desktop using the wrong menu tree. That aspect seems to be ok though as the lxde one contained a lot of kde apps.

I need a spell checker in this mailer especially if in a hurry so please excuse etc.
