I'm on Ubuntu 10.04 with GNOME 2.30.
Once every couple of days, I might be pressing something or doing something – I haven't found out what it is, though last time I was pressing the "mouse lock" button on my on-board mouse on my laptop – my keyboard simply locks down.
Some keys work, like
ALT+CTRL+F1-6 and also
ALT+SHIFT still changes the keyboard layout,
but everything else doesn't work, no letters, no other shortcuts.
To fix it, I go to
ALT+CTRL+F1 (Terminal) and run
sudo /etc/init.d/gdm restart
But I'm getting kinda tired of doing that every now and then. Any ideas if in Gnome there's a shortcut for "Kill my Keyboard" or something?
