After clicking with right mouse button on the top menu of any application, submenu "activities" is not shown in the popup menu. Moreover, any launched application is shown on all activities. I am sure this is not the default way for a clean KDE install. The same bug was in 4.11.5, as far as I remember, or maybe even earlier, but rather not in 4.11.3. Reproducible: Always Steps to Reproduce: 1. Go to ~/.kde4/share/config/kdedrc , find Module-powerdevil and set autoload=false. If there is no such section, create it: [Module-powerdevil] autoload=false 2. Load KDE. 3. To be completely sure, get at least 2 activities on. Open an app. Right-click the titlebar. Actual Results: A popup menu is shown, with no "Activities" submenu, so I cannot change activities. Expected Results: A popup menu which allows changing activities for the window. Minimal Working Example is as follows. Be sure KDE is not running. Make ~/.kde4 directory empty. Create ~/.kde4/share/config/activitymanagerrc with contents: [activities] be44afbd-64e9-44b6-a6a7-419725309ac3=Base d4beafed-cc43-4eb5-bdcc-5c8bf5ca4e6d=Second [main] currentActivity=be44afbd-64e9-44b6-a6a7-419725309ac3 lastUnlockedActivity=be44afbd-64e9-44b6-a6a7-419725309ac3 ontologyVersion=1 runningActivities=be44afbd-64e9-44b6-a6a7-419725309ac3,d4beafed-cc43-4eb5-bdcc-5c8bf5ca4e6d Create ~/.kde4/share/config/kdedrc with the following: [$Version] update_info=kded.upd:kde3.0 [Module-powerdevil] autoload=false Now run KDE and enjoy no simple way to choose activities for windows.
I also see this. I've seen this a few times in the past few months. It comes and goes. Right now i have 3 activities open. In the context menu of any window i see Move to Desktop Minimize Maximize Attach as tab to More actions Close I have also closed stopped activities and restarted them, but the menu does not appear. I'm on Debian Sid, KDE 4.11.3.
I just logged out, logged in. Only my main activity is running. "Activities" was missing from title bar menu. I started an activity and the menu item appears.
Have you tried changing "autoload=false" for powerdevil?
I'm seeing this as well on Fedora 20 now since I ran an update that installed kde 4.12.4. There is no powerdevil section in my ~/.kde/share/config/kdedrc
This is for the old Plasma 4 implementation. Plasma 5.9 has a new implementation of the menu bar.
