Kubuntu won't detect second monitor after nvidia install

in flag

My Kubuntu 20.04.3 stopped being able to detect my second monitor after installing the nvidia-driver-390 recommended graphics.

One monitor is connected to the card an the other to the board.

Apparently (am a Linux noob) the xorg server isn't detecting the second monitor anymore as you can see in the xrandr command bellow

However the device is detected by the OS which you can see when I run lspci -v | grep VGA. Both monitors are connected to a VGA entry.

lspci -v | grep VGA result

00:02.0 VGA compatible controller: Intel Corporation Xeon E3-1200 v3/4th Gen Core Processor Integrated Graphics Controller (rev 06) (prog-if 00 [VGA controller])
01:00.0 VGA compatible controller: NVIDIA Corporation GF119 [GeForce GT 610] (rev a1) (prog-if 00 [VGA controller])

It seems that xorg isn't detecting the monitor at all but the OS is. Am really at the lost here.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
