Screen keeps turning on and off - Ubuntu desktop - GT1030


I have a Philips utlra wide screen (5120x1440 px) and after logging in, most of the time, the screen keeps going off and on every few seconds. This is not always the case, sometimes it works again and everything seems perfect, but i can’t figure out why. It seems that this mostly happens after the computer comes from sleep mode.

I use the display port on the video card, with an adapter to HDMI (on the monitor). But I don’t think that’s the problem, because sometimes it works fine.

I’m using the additional drivers from Ubuntu, i switched back to 470.103.01, with no effect.
