Comment 6 for bug 81854

I have a definite cause for keyboard lock.

Using the "Terminal Server Client" I have DHCP on my network and my laptop gets a different IP address everytime the router is reset. It changes IP from 20 to 21 for example. Pressing backspace and then 1 opens the dropdown in TSClient. While the TSClient is dropped the keyboard just totally locks and you cannot work the keyboard at all. Only option is to jump to tty and kill rdesktop, when you return to the desktop you will see a disconnected screen with the IP addresses displayed.

Process to unlock is:

Ctrl-Alt-F1 (jump to terminal mode)
sign in
ps -fu username | grep rdesktop
    look for the process number is second column, eg 1234
kill 1234
exit
Ctrl-Alt-F8 (May be F7 or F9 not sure why, get back to your graphical session)
    You should see and reconnect box and a phantom list of IP addresses.
hit cancel.
   You should see the terminal services box now with the IP box expanded,
click on you IP (to close the drop box).
click OK as you normally would
    Everything should be OK now.

I have experienced the 'Network lockup' however Ctrl-Enter always works and I hit X at top right and then reconnect and everything comes back. This happens when I change the IP address on my desktop, I have a problem with network manager at present requiring a manual config.
