Hi Mal,

> Does it 100% of the time on my setup 

:-\
Any change that you ask others (users list? ) for their experience, eg with KDE <> Gnome ?
Comment 4 mal 2012-02-09 04:58:13 UTC
Had a little play. 

We don't normally use Gnome ( which is basically why we use openSUSE )

Anyway with Gnome it doesn't go black it just works as per bug 34531
( see comment 16 )

Also ...off topic .. how do you stop the primary screen getting the
navigator screen it alway appears whatever

Was a different issue? Choosing Display1 or Display 2 does make a difference here.

Comment 8 mal 2012-02-09 06:10:09 UTC
This might all be related to having SmartBoard software on the machine
Whilst this isn't your average setup it's very common in schools.

Even on Windows XP when you have a piece of software that tries to
do clever things with the screen ( Like Sibelius ) it causes
Smartboard to have problems as they all seem to fight about 
who owns the display

Bug 34531 is the more interesting one as that bug is a show stopper.
This is just a pain as it only seems to effect KDE. I hate Gnome
but it works. Personally I would rather see resources fixing 34531
first and then come back to this if it came to it

@ mal
Thanks for bugreport
Please, change Tools->Options->LibreOffice->View->field "Use Hardware acceleration" and tell, if bug still remains
Comment 10 mal 2012-04-03 08:01:38 UTC
I checked quickly and this doesn't seem to happen anymore however 
bug 34531 does ( which is nasty )

I will experiment further and get back to you  - If there is 
anything you want me to try just let me know

best wihes

The bug as originally described doesn't happen now
I have updated my openSuse 12.1 and used the LO
as per attachment. So I guess you can close this one.

However ...

The other attachment is what happens now after you
end a presentation with hardware acceleration ON

With it off everything seems fine. ( other than 
bug 34531 still exists - which I don't know if
it's related ) 

best wishes

Thanks for additional testing
Due to last comment, changing status to WorksForMe

If problem will appear again, please, change status to Reopened
(or create another because people usually dislike to read long bugreports)
Comment 15 Cor Nouws 2012-04-15 03:55:52 UTC
