I am using Ubuntu 12.04 .
Generally in Ubuntu with Ubuntu-desktop i can get desktop notifications if any new updates are available for the system. But i am not getting such type of updates in KDE. Is there any way to enable them in my PC ?
1) Is the "Check for updates" enabled ?
2) Is the System Notification for the updates enabled ?
KDE System Settings > Application and System Notifications > Manage Notifications; Event source: System Notification
At here: When those are enable the Kubuntu/KDE is checking the updates and notifying those.
Q & A
Do you have the package: muon-notifier installed ?
