I have an Acer Nitro 5 and I recently installed Ubuntu 21.10. I noticed a bit of lag when I tried semi-intensive stuff, then realized I was running the Intel Integrated Graphics. I tried multiple steps to try to get Nvidia as the default, and I think I did, but the problem now is my 2nd monitor won't turn on. When I go into the installation media on the USB, it works as expected. But when I return to my normal, installed OS, it won't work correctly.

I have tried multiple methods, but I am unable to find the links to them all atm, so feel free to pitch your solutions and I'll let you know if I tried it.

Things I have tried: Restarting, unplugging/plugging, reinstalling drivers, switching drivers, and attempted to disable Secure Boot (which I couldn't figure out).

Update: I was forced to do the password stuff and BOK password, now my external monitor works but the internal one doesn't.

Yes, you either disable Secure Boot or you set trust via a password with the **MOK** utility. With that out of the way, why isn't your internal monitor working? Have you checked system settings > displays? It should be there and likely disabled. Set the options accordingly.

@ChanganAuto I just checked, I don't see any option to disable the internal monitor, I only see my external monitor listed. Is there another way to see if it's detected or just disabled through anywhere else?

@ChanganAuto I entered xrandr in the terminal, and it appears that the internal monitor isn't even detected whatsoever, similar to what happened with my external monitor.

I have found the solution. This was the code line I used. `cd /etc/X11 sudo rm xorg.conf sudo cp xorg.conf.nvidia-xconfig-original xorg.conf reboot`

The answer to this was a lot, but here it is.

The original problem, which was the external monitor not working, was solved by typing the MOK key to enable Secure Boot. (Though, disabling it works too supposedly).

The next problem, the internal monitor not working, was solved by this command line. (As seen with the lines, it works with Nvidia specifically)

cd /etc/X11
sudo rm xorg.conf
sudo cp xorg.conf.nvidia-xconfig-original xorg.conf
reboot

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.
