[BRLTTY] Strange problem when switching back to X & restarting brltty

[Halim Sahin]

Hi,
I think the display is locked  and sometimes orca does not display
anything since you move eg. the mouse arround.

This is the reason why I do not use lightlocker.

To lock the machine I switch to tty1 and use 
vlock -a
HTH.
