Recently upgraded to Ubuntu 22.04 and now my monitor is shown as 'Uknown Display' and second monitor doesnt even show up

I followed some basic instructions:

ubuntu-drivers devices and and ubuntu-drivers autoinstall to install the nvidia nvidia-driver-515 but my monitor, which is Benq XL2411, is shown as Unknown Display without beeing able to put 144 Hz.

Can I somehow fix this super weird ubuntu-thing?

I think display driver is broken in the new 22.04. Ubuntu have to test the nvidia drivers before putting in their repo, as I tried their tested nvidia driver and I have the same issue. My external monitor is not recognized. I tried to use the X.Org the open source driver, which beautifully recognizes the second monitor but it crashes my other applications like zoom client etc. So right now we need to wait for a patch or update to fix this.

I tried versions 390, 418, 450, 455, 460, 470, 510, 515, 525. Unsuccessful.

Can't get more than 1600x900. Tried it on DVI-D. Didn't work. If I try to use xrand do add full hd res, is returns error:

X Error of failed request: BadMatch (invalid parameter attributes) Major opcode of failed request: 140 (RANDR) Minor opcode of failed request: 18 (RRAddOutputMode) Serial number of failed request: 37 Current serial number in output stream: 38

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.
