I have noticed this only happens after running a full screen application
like a game. For example I run a game like Dying Light or Left 4 Dead 2
in steam and after I close out of the game, that is when I get the
flashing. After a reboot everything is fine until I run another full

Title:
Screen flashes
I have found that if I turn off the composter the flashing will go away.
So it is somewhere in the composter code. Using the alt-shift-F12 keys I
can toggle the flashing. It comes back as soon as I turn the composter
back on.

I used a blank drive and installed 17.10 I then did all updates with no
other PPAs enabled besides the default Kubuntu ones. The driver
manager did ask if I wanted to use a propitiatory Nvidia driver and I
said yes and let it install the default Nvidia driver. I installed
nothing else. I
I have this problem. Everything works great with my two monitor setup
until my screen blanker comes on. After I wake the system (which my
secondary monitor seems to wake up a couple of seconds faster) when I
click the application launcher, the screen opens up on my secondary
monitor. All
I have this issue, even my sound preferences change. I have my onboard
sound as default and after waking the monitors it defaults back to the
HDMI sound device.
