Anyway I had a similar problem today. My Pause key, when pressed, would simultaneous ‘mute’ my audio *and* turn it either ‘up’ or ‘down’ (with a preference for ‘up’). Friggin weird. Anyway I was able to fix the issue by doing a keyboard reset.
To do a keyboard reset: unplug the keyboard, set SW4 to the “on” position, plug it back in. Wait until the solid green lights emit and then unplug, set SW4 back to the “off” position and then plug the keyboard back in and test. Easy peasy. :)
So I knew there was an expression that sounded like “on your pattern alone” and I knew the word “pattern” was wrong; turns out there’s an Australian slang idiom “you’re on your Pat Malone” which is rhyming slang to say that you are “alone”.
There is a feature of NetBeans where it puts a red line as the right margin in the code editor. By default this margin is at 80 characters but I prefer it at 99 characters. To change the setting in NetBeans see Tools -> Options -> Editor -> Formatting -> All Languages -> Tabs And Indents -> Right Margin. For example:
Note that if your Kubuntu install is a VirtualBox guest you need to start it with a normal start if you want the shared clipboard to work. If you start headless or detachable the shared clipboard will not work (in my experience).
If your Kubuntu install is not a VirtualBox guest you can skip the virtualbox-guest-* package installation above.
