Public bug reported: Binary package hint: udev
OS Version: Ubuntu Maverick Meerkat 10.10 i386 Problem: When pressing the Fn+F5 hotkey on a Dell Latitude E-series laptop to toggle the touchpad, the correct keycode is sent, but, the touchpad does not respond. Instead, there are other side effects such as loss of keyboard that occur. Details: The laptop is using an ALPS touchpad, which present themselves to the operating system as ImPS/2 ALPS GlidePoint Devices. Steps taken to reproduce: 1) Press Fn+F5 to try and disable the touchpad. 2) This does not disable the touchpad, but, the side effect is that the keyboard stops working to some degree. For example, if you have a terminal window open when pressing Fn+F5, you can no longer type anything into the terminal window. The other side effect is that although the mouse pointer still works, you cannot click on anything either by tapping the touchpad or clicking the mouse buttons below the touchpad. 3) To clear this, press Ctrl+Alt+F1, then Ctrl+Alt+F7. You will then be able to use the keyboard again on the desktop. Also, note that the notification icon shows up in the upper right corner of the screen showing "touchpad off", even though the touchpad was never really disabled (this is a different problem). 4) After restoring keyboard functionality by running through the above in step #3, Fn+F5 does not respond again until the system is rebooted. Per a conversation with Martin Pitt on this issue, he requested I open a udev bug regarding what appears to be some sort of 'stuck' key issue that could possibly be addressed with udev.
