I have a problem like this after modify some settings in CompizConfig Settings Manager (trying to enable cube).
The workspace applet show 4 workspace and when I clicked on it, I saw only my wallpaper. No, icons on the desktop, no panels, ... So, I should be go to tty1, and type killall gnome-panel and switch back to my X session to relaunch the display all all components. I try this several times, when I click on "workspace applet", all gnome component disappears. But before click on it, I can change to different workspace with ctrl-alt-arrow and in this case it worked, but the workspace-applet didn't work , it cannot show the correct workspace. Solution : Launch compiz-settings-manager and reset all parameters : >From http://ubuntu1501.blogspot.com/2007/08/compiz-fusion-upgrade- problems-trevinos.html "If you don't know where to find CompizConfig Settings Manager (System>Preferences) or don't have an entry in your menu you can launch it by firing up a terminal and typing in: ccsm" 1. Select the preference option 2. Select the Reset to Defaults option Now Compiz Fusion will reset and everything will work again. After that, I have only two desktop. I switch to no visual effect, update the settings of workspace applet : 2 to 4 workspaces and enable desktop effect. Now, workspace-applet and compiz work together. -- loses workspaces when trying out desktop effects https://bugs.launchpad.net/bugs/145782 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
