Kubuntu not all external monitors are working

mh flag

a little while ago after updating some packages KDE has stopped functioning, all I got was a black screen, but I was able to go to terminal with ctrl+alt+f2. After reinstalling KDE (not the entire OS but just the packages) I was able to get it working again. Before that I did try to reinstall amdgpu driver but it failed. (I'm using a laptop with ryzen cpu (radeon graphics) + nvidia rtx 3070)

KDE is functionally normally, except 2 out of 3 external screens are no longer working (they worked fine before). I can only get the internal screen and 1 external monitor working. 1 monitor is connected through HDMI, 2 others are displayport using a usb-c to display port adapter. The screen that's working is 1 of the display port screens. I tried removing kscreen settings and rebooting, but this is not working.

Here's my xrandr output with all monitors connected, I have enabled 2 external monitors but only 1 is working. The others (built in and external monitor) are disabled. (If I enable the 3rd external monitor I only get half a screen..)

What can I do to get all external monitors working again?

I also tried to see if I could switch the driver using GNOME's Software & Updates 'additional drivers' tab, but it's stuck on 'continue using manually installed driver' with all other options greyed out.

Score:0
mh flag

ended up fixing it with

sudo ubuntu-drivers autoinstall

I was hesistant using this earlier, because I've used it before and resulted in black screens. But this time it seems it fixed my nvidia driver the easy way. :)

after this the external monitors were working, but still were slow with rendering (only rendering properly when my mouse was at that screen). I fixed this with the command

nvidia-settings

then at 'PRIME Profiles' switch to NVIDIA (Performance Mode). After a reboot everything worked normally.

when running amdgpu-install it still shows the sam error (not finding libffi7, but I can't seem to find how to install this package). If anyone can clarify why this happens and how to fix (if I should fix it) that would be great.

I sit in a Tesla and translated this thread with Ai:

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.
