Got a dual boot computer with Windows 8.1 and Ubuntu 20.04. Decided to boot Linux for work and the resolution became unexpectedly low (1024x768).

Display resolution size:

Apparently I have only one mode available to set the resolution and NVIDIA VGA compatible controller.

Tried to modify 2 files with:

sudo gedit /usr/bin/compiz

and with:

sudo gedit /etc/X11/xorg.conf

but they are empty

xorg.conf:

compiz:

The recommended NVIDIA driver is already installed

Installing another outputs an error.

I have a monitor of 1440x900, and it's working OK on Windows.

Disable Secure Boot in UEFI and try again.

if you have an NVIDIA driver controlling a NVIDIA display card then consider

sudo apt install nvidia-settings

I use this app to change my display card settings all the time. In my case, I have to use X11 as my display manager, because Wayland does not work with my display card.

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.
