14.04, orca, brltty

[Tom Masterson]

Starting especially yesterday but off and on since I updated to 14.04 orca 
has stopped working with the braille display.  I see nothing in any of the 
logs that gives a clue as to what is happening.

When I get to the log in screen everything is working fine.  When it goes 
to the desktop braille is no longer working.  Sometimes a reboot of the 
machine does help.

I am also noticing odd behavior at the console where occasionally my 
display cursor movement keys do not work or all of a sudden it will decide 
to just run everything to the bottom of the screen like I was holding down 
the down key on the display.  The only way I have found to resolve these 
issues is to disconnect and reconnect the display and/or restart brltty. 
My display is an Alve BC640.
