I found a way to reproduce it. It happens when the mouse pointer jumps between the two displayport monitors. If I keep moving the mouse between the two monitors it happens each couple of seconds.
If I disable the vga monitor. The problem is gone... I have no idea of what is happening but at least know that disabling the vga monitor solves the issue for me. Hopefully someone will find out what is happening. -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to evince in Ubuntu. https://bugs.launchpad.net/bugs/1574617 Title: External monitor keeps going blank To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/evince/+bug/1574617/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
