Hi,

I've a bunch of people running low powered thin clients (LTSP) to access a Kubuntu Hardy server (KDE 3). Been running very well for years and everyone's happy.

However, with Hardy LTS approaching its end of life I'm having to look at moving to Kubuntu Pangolin and KDE4 and the lack of compositing in a VESA X-Server (remember these are low powered thin clients) means that I can't zoom out and see what's on different activities.

This rapidly starts to get annoying as I *know* I've got rekonq open somewhere.... but I have to click on each activity then look at each desktop in each activity to find it

Is there a better way of handling this (yeah yeah... buy everyone a new thin-client with a better GPU... that's not going to happen)? I already have enough support calls from people 'loosing' things on virtual desktops; adding in virtual desktops inside activities they can't see is going to compound the problem horribly.

I'd also ask if it's possible to limit the number of activities for a given user; but that's probably heretical so I won't

Depending on how you configure the Task Manager widget, this issue could be avoided entirely.
Plasma allows you to configure which windows in particular will be hidden. You could configure it to ignore activities for the purposes of hiding windows (ie. show the windows regardless of what activity it is in). You could also do this for Virtual Desktops I believe.

bcooksley is correct. The task manager allows to toggle:

• Only windows in the current activity
• Only windows in the current virtual desktop
• Only windows in the current screen (for multi-screen setups)
