Public bug reported:
I have 2 monitors, (connections: VGA, HDMI). When 1 monitor (LG IPS237) is
using HDMI - it can blink for 5-10 mins from reboot (1 second off, 1 second on)
If both monitors are connected using VGA - there is no blinking, but I had
strange glitches (that's why I used HDMI)
And the fact that it is blinking with this connection type is really f...ing
annoying.
PS: It only blinks when in Nvidia X Server Settings this monitor is set
as "primary" (which is in my case, and I want this setting to stay)
