I'm using the latest version of Ubuntu, with a Wi-Fi adaptor that Ubuntu detected flawlessly.
When the internet drops out, Ubuntu gives me a notification bubble in the top right of the screen, e.g. "Wireless network, Disconnected". There is no clickable "x" on these notifications and I can't seem to stop them from returning over and over and over, about once every 5 seconds. To make matters worse, I can't access the network settings menu in the top right of the screen, because every time I open the network settings meny, a notification bubble pops up and cancels the menu. This means I can't configure my network, which is what Ubuntu is complaining about.
So, the short question: how can I disable those notification bubbles? Or, what must I do to acknowledge a bubble so that it doesn't pop up again and again and again unless there has been a significant other event?
