The latest release of gnome-terminal has removed the ability to disable the blinking cursor, which I had previously turned off. The only way to disable it is to disable blinking cursors in all text entry widgets. For some reason I prefer the cursor in text boxes to blink, but cannot stand a blinking terminal cursor. Every blink jars my mind and I lose focus, like someone's looking at me waving his hands and yelling "hey!" every second.
Blink. Blink. Blink. Arrrgh.
Anyway, since the developers saw fit to remove this feature presumably under the GNOMEism of "keep things simple, users be damned," I have coded a quick patch to permanently disable cursor blinking in gnome-terminal.
As frustrated as I am at what I think is a stupid decision, at least this is free software.
