What is the blue triangle on the home button for?
I regularly have a gap in the upper-left corner of the button for the Unity launcher. It is almost like a beveling of the global menu bar. It seems common when using Chrome, but it also occurs when I am using other programs, such as nautilus. I find it quite annoying. Is there anything I can do?
If you are referring to the blue thing, it is a part of Unity in 11.04, and I don't think you can disable it (at least I don't remember being able to; I'm on 11.10 now). It only appears when an application requires your attention.
When you're saying "gap", do you mean that blue triangular marker in the upper left corner?
It's actually not a gap, it's an indicator that one of the windows in the launcher requires your attention (the same thing is indicated by a blinking/pulsating icon or button in other window managers - since the Unity launcher is hidden most of the time, just pulsating the icon would make ne sense)
I guess it may look like a "gap" if your wallpaper is of a similar blue color... but it is not.
