Comment 6 for bug 758335

In gdm, when you hold down the shift key for 8 seconds, Slow Keys gets turned on *silently*.

In a user session, #41427 is a known issue that the pop-up notification about this sometimes is invisible because it is behind other windows, and that the default is to enable Slow Keys if there is no user action. But in gdm the situation is even worse - no pop-up or any other notification ever appears. To any user not already familiar with Slow Keys or how to turn it off, the effect is that the keyboard becomes unusable.

This is a grave usability issue for the entire system.

For those arriving here not knowing what to do: there is an "Accessibility" icon on the task bar at the bottom of the screen. You can use it to open an accessibility preferences dialog. Uncheck the Slow Keys option.
