I have a logitech coreless keyboard that has always "just worked" and I've lived without programming any keys, no factory. no tumbleweed, recent fresh re-install of 11.4, updated generally and with kde 4.6.5, xorg 7.6, nvidia driver 275.21

Mysteriously, the down arrow key no longer works as it should, (up, left, right are fine)

Rather it has the effect of crashing the transparent task manager and adjusting the focus of open windows.

If I repeatedly hit the down arrow key the focus toggles and then transparency is re-enabled.

The best way I can describe the effect is that it is as if I were using [tab] to toggle through a text based menu (e.g., YaST launch in terminal mode)

May I ask if anyone has any thoughts?

If you run xev in a terminal and press the down button, what does the output say?

Thank you for replying

I don't understand which part of xev output is useful
the following is xev <return> <down arrow>

Code: Select all

I do not see a KeyPress event in your listing. I have no idea the significance of that.

Oh, I thought I had replied to gerryg's latest post, but apparently not.

I also find it strange the a KeyPress Event is missing. Can you see if the Down arrow key works correctly for a new user? Maybe you accidentally bound it to a keyboard shortcut.
