I recently got a new computer, and when I installed linux on it—Ubuntu to be specific—the screen resolution was set to 1024x768. I tried adding a new mode, but when I tried switching to the new mode the screen didn't change. I have two drives on this computer—one is a ssd that has Windows installed on it, and the other is a regular hard disc that has Ubuntu installed, I am having no issue with screen resolution when I am on windows, I tried looking for help everywhere, but I couldn't find any, so this is my last option, I'm really tired right now, I was so excited when I got a new computer, now I am dealing with this crap :(

Screen 0: minimum 320 x 200, current 1920 x 1080, maximum 16384 x 16384
VGA-1 connected primary 1024x768+0+0 (normal left inverted right x axis y axis) 0mm x 0mm

You've not provided any Ubuntu product or release details; are you using Xorg or Wayland? (*release details are a good start for us to understand your software stack & thus provide advice specific to your situation*).

I suggest you update your question with the full output of `xrandr` before you ran any additional adding resolution commands and also instead of saying "I tried adding a new mode" detail EXACTLY the commands you ran etc. Also state what make/model of monitor and exactly how it is connected to your PC. Is it direct VGA cable or via an adaptor or dock? Also, this is a good resource and instructions for `xrandr`: https://wiki.archlinux.org/title/Xrandr#Adding_undetected_resolutions

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.
