I've read that fc17 is end of life but maybe someone has run into
this.  I'm
running fc17, latest upgrades, using XFCE, and periodically the
keyboard
just stops working, mouse is fine.  I end up having to mouse over
ALL of my
open windows saving and closing.  Once I logoff and logon
everything works
normally.  I've checked the Xorg log, messages, dmesg, everything
I can
think of but its sill happening.  I even tried turning off the
screen saver
but that didn't help either.  It happens inconsistently which
makes it even
more annoying :)

Not sure there's a single answer given the possible moving parts
involved.
If nobody can think of anything off the top of their head could
someone
suggest a good way to try and debug?  I'll be upgrading here
eventually but
right now the timing is not optimal.

Can you change to a virtual console (Ctl-Alt-Fn where n!=1) when
this
happens? (And if not can you do it normally?) N.B. Alt-F1 should
get
you back to the desktop. Might help in working out whether this is
a
problem with X or with XFCE.

Also, may want to check you've not accidentally turned on some
accessibility option like sticky keys. (This used to catch me out in
KDE because a long shift keypress enabled it, until I got fed up
enough to turn that off.)



Good idea, I have not tried the virtual console check, I will the next

time it happens.  Any idea how to turn off sticky keys in XFCW?  I
found
a suggestion using xkbset.
If that doesn't work, try holding down the shift key for 20 sec.


Thanks all. The shift key thing worked, the question is how did sticky keys get turned on in the first place? Luckily when it happened this morning I had been tailing my syslog.

I had left my machine on all night because I was working on something. I turned on my monitor, Alt tabbed over to Firefox, logged onto a remote site, then tabbed over to Thunderbird, tabbed back to FF, lock. Moused back to Thunderbird, read Joe's response, followed his instructions. Sticky keys wasn't enabled so enabled it but also selected 'Disable sticky keys if two keys are pressed' figuring that if the keyboard is reset; sticky keys enabled with this option, at the very least I could disable it with the two key approach. Once I left the dialogue box I tried the keyboard, didn't work. Moused over to the syslog screen and didn't see anything. Tried the two key operation and one of the letters showed up in the syslog! Now it didn't show up as an entry in the log, but showed up on the screen nonetheless so at least the keyboard was working in some fashion. I then tried Geoffrey's suggestion and it worked.

So, judging from the fix, somehow sticky keys got turned on this morning after very little, and no prolonged, keystroke use. Going into the accessibility dialogue showed sticky keys wasn't turned on previously either. Turning it on there I don't think had any affect because I think the dialogue box was reporting it was off erroneously.

Ultimately, holding down the shift key for 20 secs worked. So I think there is a solution but I'd be interested to know what avenue I could take to actually see it happen and get to the bottom of it? I'm not going to lose any sleep now that I have a work around but it has piqued my curiosity. Thanks for all of your help so far.
