HDMI-0 Disconnected When Plugged In Ubuntu 21.10

cn flag

My external monitor (Classified as HDMI-0) is not turning on or being detected when I plug the HDMI in my computer. I have tried replugging the monitor in as well as restarting my computer.

Here is the xrandr output.

What version of Ubuntu do you use? Could you provide result of `xrandr --listproviders` and `xorg.conf` content?

@Serg I am using Ubuntu 21.10. `xrandr --listproviders` output is : `Providers: number : 2 Provider 0: id: 0x1b8 cap: 0x1, Source Output crtcs: 4 outputs: 1 associated providers: 1 name:NVIDIA-0 Provider 1: id: 0x1e1 cap: 0x6, Sink Output, Source Offload crtcs: 3 outputs: 1 associated providers: 1 name:modesetting` `xorg.conf` command wasn't found.

Sorry, please provide output of `cat /etc/X11/xorg.conf`
ch flag
Also you have 2 video cards, could you please provide information about the second card (the first is nVidia)
ch flag
And run `xrandr --output HDMI-0 --auto`

@Serg The 2nd GPU is an Intel iGPU, the Intel UHD 630 I believe. `cat /etc/X11/xorg.conf` had no output whatsoever. Same thing with `xrandr --output HDMI-0 --auto`

I solved it through a system update which restarted my computer, I don't know how or why but it worked for me.

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.
