how to bring back toggle desktop effect widget on plasma panel

[lemorte]

After doing latest update on kwheezy 1.3 installation, I have two errors. One cannot install linux-image, so I apt-get remove remove and install latest linux image. Two toggle desktop effect was gone, showing the big X. So I remove it.

Any clue to bring the widget back?

Are you sticking to the wheezy repo's only? In which case you shouldn't have any issues updating the kernel. But if you have testing or backports enabled in your sources.list then it's better to uninstall all the "live" cd tools, since they interfere with kernel upgrades.

Please describe the widget(s) you are missing. If the widget is not longer available in the "add widgets" menu then a package must be missing. Search for packages with "plasma" in their name. Below is a list of mine:

$ dpkg -l | grep plasma-widget | awk '{ print $1 " " $2}'
ii network-manager-kde
ii plasma-widget-adjustableclock
ii plasma-widget-daisy
ii plasma-widget-fastuserswitch
ii plasma-widget-folderview
ii plasma-widget-lancelot
ii plasma-widget-menubar
ii plasma-widget-message-indicator
ii plasma-widget-networkmanagement
ii plasma-widget-telepathy-chat
ii plasma-widget-telepathy-presence
ii plasma-widget-toggle-compositing
ii plasma-widget-translatoid
ii plasma-widget-veromix

well i always disable backports and unstable (sid) before updating. and i stick with 3.2.0-4-amd64 stable kernel.

ok find out from the list it was plasma-widget-toggle compositing. but everytime i add to plasma panel it will display the big X. maybe clean reinstall would do just fine.

That's strange. If you installed back the plasma-widget-toggle-compositing package, it should just work. You may have to remove and add back the widget.

I noticed you did a clean reinstall, that should fix it for sure. :-)
