Hi,

I have a dual-screen setup with Debian wheezy and every hour and 7 +/-1 minutes
the main screen starts kinda like quickly zoom in and out twice and after the
other screen does the same twice too.
After upgrading to Debian jessie the same "zooming" happens but changed now to
every ~16 minutes, sometimes only laptop screen once, sometimes external once.
It happens in KDE but also if I log out and am in console.

It's not happening when external display is not plugged in.

Is there a way to log something like that? Cuz can't find anything in the logs
lookin right after it occures.
Searching the net for this kinda error led me to someone mentioning it could be
upowerd, but I monitored D-Bus and nothing showed up as the zooming occured. I
also checked out /var/log and .xsession-errors but nothing.

I cannot try it with fglrx because it seems the VGA compatible controller
