Hello,

Have I lost my tilde key ?  Does it work for anyone ?

It's the key with keycode 0, right? On most architectures keycode 0 is ignored,
we had an #ifdef to enable it. Perhaps someone reverted the code
(drivers/char/vt.c, I think).

Note that according to Andries Brouwer there exists a security problem if you
allow keycode 0, so alternatively you can remap it to an unused keycode number
in the Amiga keyboard driver. The disadvantage of that solution is that all
keymaps in all distros have to be modified as well.

Hmm, I can't find any relevant change...
The strange thing is, shift+tilde works now as sysrq key?!
Any idea, how this could happen?

Think it is 0 from memeory.

Oh great!

Is the exact nature of the security problem posted anywhere ?

Sounds awful .... ;)

Every few months someone asks this, then I reply with Andries' message, and
nothing happens :-)

BTW, I don't have his mail here, but using Google I found this:

    http://www.uwsg.iu.edu/hypermail/linux/kernel/9804.0/0764.html

It looks like you can deallocate the keymaps using keycode 0.

Somehow the initialization of the SYSRQ key got lost, it works now
again.

Working again.

Did the keypad ever work ?

There's something funny going on.

Sometimes it's dead, sometimes it types rubbish, sometimes it looks
like its cursor keys, sometimes numeric.  This is not application
dependent, just at a shell prompt in X or console. 

One or both bracket keys sends a ^S.

Can't see a pattern to it's weirdness.

Is it only me....
