Please choose a single problem to focus on and reword the bug to only describe that problem.

Hi, ok.
Computer not detect the second screen on Nvidia 440 driver and also integrate video card. - intel hg 630/ coffee lake.

[Valdis Strautins (wd-market)]

So I just did try to add different monitor with nvidia 440 driver, it did detect second monitor.
So it seems driver don't want to recognize my monitor. But integrated graphiics card still dont recognize second monitor - https://i.imgur.com/zv1BIQI.jpg(when I use it)
Thanks

[Daniel van Vugt (vanvugt)]

Thanks. The attachment 'Xrandr.txt' indeed says no second screen is plugged in. But I don't know if Nvidia or Intel is to blame here without knowing which GPU it is wired to.

[Valdis Strautins (wd-market)]

When I set up performance mode, both screens work.
I guess when intel graphics is enabled then the second screen is not detected.

I could leave performance mode.
But if I set up performance mode, the computer gets hot and battery discharging fast.
Thanks

[Daniel van Vugt (vanvugt)]

That suggests to me the ports are wired to the Nvidia GPU. But that's not an excuse for this bug; it's still a bug.

The bug description at the top of this page currently says it doesn't work in performance mode so please reword that if it is wrong.

[Valdis Strautins (wd-market)]

Yes, it is a bug.
I have a long time spent to are run Linux on this PC and no results.
It doesn't detect the second display in power saver mode in Nvidia options.

Thanks
