Hello,

I'm not sure if my problem depends with noticed changes. I use Czech
braille display which use alva protocol. I installed a new ubuntu
installation and new brltty installation from svn repository. First I
though that I have problem with my driver for my video card (ATI Radeon
X1270), but later I check taht the problem is probably in brltty. On X I
use orca and speechd-el together, that means I use xbrlapi that will be
possible switch between orca and speechd-el.

But if works both then after switching to other window with alt-tab the
screen locks and I must with control-alt-f1 for example go to text
console then back, then press again alt-tab and then in most of
situation it works. If I use one application orca or speechd-el only
without xbrlapi, then I have no problem switch between windows.


Bellow you can find more information from brltty log:
