Button, button. Who's got the button?

As much as I try, I can't switch away from GNOME. Every once in a while I will try to use some other desktop environment in Debian and I invariably switch back after a month. The fact is that for me, GNOME seems to come with fewest little annoyances that need manual fixing or digging through configuration files or source code. Or it might be that I'm just too used to all the small details in how GNOME does things on the user interface side. It's also possible that I understand enough about GNOME internals at this point that when things stop working I usually find the solution pretty quickly.

That does not mean, however, that GNOME no longer manages to surprise me. This is a story about the latest such occurrence. It's a story about a button. This button in particular:

Rotation lock button in GNOME 3.14

I noticed this button after upgrading my work laptop to Debian Jessie that comes with GNOME 3.14. The most curious thing about it was that it does not appear on my home desktop computer with a supposedly identical Debian Jessie setup. What makes my laptop so special that it sprouted an extra button in this prime piece of screen real-estate?

Being the kind of person that first looks into the documentation, I opened the GNOME 3.14 Release Notes. However, there is no note in there about any mysterious new buttons on the click-top-right-corner menu. I was not surprised though, since it might have been added in any of several GNOME versions that were released between now and the previous Debian Stable.

The button is marked with a circular arrow icon. The kind of icon that is often used to distinguish a reboot in contrast to a shutdown when positioned near the power-switch icon. Like for instance on this Ubuntu shutdown dialog:

I don't think it was unreasonable then to assume that this is a reboot button. Anyway, when documentation about a thing fails you, the best next step is usually to poke the thing with a stick. Preferably a long and non-conductive one.

Unfortunately, this approach failed to uncover the purpose of the mysterious button. Upon closer inspection the button did change a bit after clicking on it, but seemingly nothing else happened. On the second thought, it would be kind of weird for GNOME to have a reboot button when at one point it lacked even a shutdown option, for a reason nobody quite understood.

In a final attempt to discover the purpose of the catching-its-own-tail arrow, I hovered the mouse cursor over it. Of course, no helpful yellow strip of text showed up. Tooltips are obsolete now that everything is a smartphone.

At that point I ran out of ideas. Since I had no text associated with the button it seemed impossible to turn to a web search for help. In fact, I realized I don't even know how the menu that holds the button is called these days. I complained about it on IRC and someone suggested doing a Google Image search for the button. This first sounded like a brilliant idea, but it soon turned out that visual search for graphical user interface widgets just isn't there yet:

Results of a search for visually similar images.

Of course, I was stubborn enough to keep searching. In the end, a (text) query led me to a thread on StackExchange that solved the conundrum. I don't remember what I typed into Google when I first saw that result, but once I knew what to search for, the web suddenly turned out to be full of confused GNOME users. Well, at least I was not alone in being baffled by this.

In the end, I only wonder how many of those people that went through this same experience also immediately started swinging their laptop around to see whether the screen on their laptop would actually rotate and were disappointed when, regardless of the screen lock button, the desktop remained stubbornly in the landscape mode.
