[Bug 124406] Re: Keyboard keys get stuck and repeat (Feisty, Gutsy)

[Xavier Aragon]

I upgraded two machines from Intrepid to Jaunty and started having this
problem of stuck keys. It never occurred before the upgrade, and as the
two machines have very different hardware, I would imagine the problem
is not hardware dependent.

I have two ways of reproducing the problem:

1) In a gnome terminal say 'xset r off' to turn off autorepeat (assuming
it was on initially), and I have the enter key stuck (repeating as if it
was being pressed). Hitting enter again does not stop the repeating.

2) When running a VMWare virtual machine in a vmware remote console
window, hit the title bar of the window to give it focus, then press
Ctrl-G to enter the virtual machine. The key 'g' starts repeating like
if it was being pressed down constantly. I don't know exactly what the
vmware console does when activated, at least it grabs the keyboard and
mouse, perhaps it does something to autorepeat settings as well.

The way I can recover from the "stuck key" condition is to somehow issue
the command "xset r rate 500 3" or something similar with a very slow
repeat rate (3 times a second in this example), and then hit any key.
Turning autorepeat off with 'xset r off' does not help, but a slow
repeat rate does. In my case 1 I can issue the command from a virtual
console by first ntering it with Ctrl-Alt-F1, but in case 2 the vmware
remote console has grabbed the keyboard and the only way to recover is
to log in with ssh from another machine to issue the command.

To me the problem seems very closely related to the Xserver's key
autorepeat functionality. It used to work before upgrading to Jaunty,
but now it is seems broken. It key getting stuck is the one that was
last pressed when some autorepeat related operation is made (in the
first example turning autorepeat off, in the second example perhaps
grabbing the keyboard or doing something with autorepeat settings).
