Ubuntu

Introduction

It has been almost a year since Ubuntu 24.04 LTS Noble Numbat was released. Since it seems to be stable enough, I decided to migrate from 22.04 to 24.04 with a clean install.

I usually installed from the Japanese Remix ISO image, but since this version Japanese Remix is not released, I downloaded the image from Canonical’s page and installed it.

Introduction

It has been a year since Ubuntu 22.04 LTS Jammy Jellyfish was released, and I decided to switch from my previous 20.04 to 22.04, thinking that I would be able to get used to the various software and other features.

I installed ubuntu 22.04 Japanese Remix on several workstations so that I can use Japanese easily. I have gotten a bit stuck trying to install ubuntu 22.04 on a NVIDIA GPU-equipped workstation, so here is the situation and how I responded.

Motivation

Immediately after installing Ubuntu, the display resolution was set to 1368x768. The screen was inconveniently small when working with multiple terminals open, and since I had connected to a display (JAPANNEXT JN-MD-IPS1562FHDR) that can display 1920x1080, I wanted to display it in that resolution.

I tried to change the resolution, but got into a bit of trouble, so here is a summary of the process.

1. Ubuntuディスプレイ解像度の変更|1920x1080 Reading this information, it seems that it is easy to change the resolution using the xrandr command, and it only takes a few minutes of work. I thought it would only take a few minutes to change the display resolution, so I started to work on it.
2. 4.3 Permanently adding undetected resolutions This is the page I referred to when editing xorg.conf.
3. External Monitor, can’t set desired resolution *This page solved the problem. I tried many things without success, and after searching the net further, I finally found an article about the same phenomenon I was experiencing.

Setup

Normal way

To change the resolution of the display, go to “Settings” -> “Display” and specify the resolution, but in my environment, there is no 1920x1080 entry in this list!
