Hi all,
Would it be feasable to modify the current keyboard
driver in such a way that it would log the last 1000
keystrokes pushed (possibly log it somewhere in /proc
or something)? When I say keystrokes, I mean
everything...even the ctrl and alt and shift bit keys
Something like this would greatly simplify the program
I am attempting to make.
Thanks
Alan

That's simple if you do it in a hackish way, but maybe a bit different
to what you think. You'd extend the struct atkbd to contain a 1000 entry
array and in rolling index. Then stuff your current keypress into the
array and you're done.
You'd need to hack in the proc interface, though.

What do you actually want to do?

specifically, I am trying to write a program similar
to the old Sidekick program of the DOS days. A
"daemon", if you will, that will popup on the screen
when a predetermined series of keystrokes are hit. The
program will then do various things, like record/play
macros, calculator, calendar, programmer's guide, etc
etc...
The part I'm having trouble with though is having it
popup when predetermined keystrokes are pushed. I
don't think Linux has a way to hook into the keyboard
(if I'm wrong, someone please tell me).

What kind of information that you need is missing if you just read
input events from /dev/input/eventX?

Then a keyboard driver isn't the good solution. You'd better write a
userspace app which uses the XTEST extension.

why not just use screen? or emacs as your shell?

Well, this sounds more like a userspace problem. Write a small app that
select()s on /dev/input/event* and get the keystrokes from there. From
there, you'd even start applikations. That's a lot more complicated to
achieve in kernel space :-)

Well, I don't think you want to tap into the kernel driver for that. I
mean if one uses X over the network I would assume that the popup
driver will run on the remote box while keyboard is on my local box.
The daemon is for X environment, right? You need to work with X
server, not kernel.
