Issue with installing Ubuntu as display resolution and Live Boot USB not working

Troubleshooting Display and Boot Issues on a PowerSpec G483 with Ubuntu 22.04

Installing Ubuntu on modern pre-built systems can sometimes present unique challenges, particularly concerning display output and booting from live media. If you’re experiencing issues similar to those on your PowerSpec G483 PC, this guide aims to provide a structured approach to troubleshoot and potentially resolve these problems.

Understanding the Hardware Context

Your PowerSpec G483 primarily outputs display via its dedicated GPU, with no output detected from the motherboard graphics port. This means:

Bypassing the GPU for display is generally not possible without additional configurations.
Troubleshooting must consider GPU-related settings and driver configurations.

Commonly Encountered Issues

No display output during Ubuntu Live Boot, regardless of USB media or monitors tested.
Boot screens appearing with incorrect or zoomed-in resolutions, making options difficult to read.
USB boot media failing to display anything after selection, with screens going black or frozen.

Proactive Troubleshooting Steps

Verify Hardware Connections and Displays
Test multiple monitors and cables, as you’ve already attempted.
Use different video outputs: DisplayPort, HDMI, and VGA adapters if available.
Confirm that the monitor input source is correct.
Experiment with Boot Parameters

Since your system’s GPU is dedicated and outputs are limited, adjusting boot options can help:

Append kernel boot parameters such as nomodeset, radeon.modeset=0, or nouveau.modeset=0 to disable graphics mode setting during boot.

For example:

When selecting “Try Ubuntu” at the boot menu, press e to edit the boot parameters.
Add nomodeset to the line starting with linux, then press F10 or Ctrl+X to boot.

This can sometimes prevent resolution issues or black screens caused by graphics driver conflicts.

Use a Different USB Creation Method and Settings

While you’ve tested several tools, ensure the following:

Select GPT partition scheme and UEFI target if your system uses UEFI.
Create the bootable USB with reliable tools like Rufus or BalenaEtcher, ensuring proper ISO verification.
Confirm Compatibility with Your System’s Firmware
If your BIOS/UEFI is outdated, consider updating it cautiously:
Check the motherboard manufacturer for the latest firmware.
Follow official instructions meticulously to avoid bricking the device.

Note: You expressed concern about updating the BIOS; weigh the benefits vs.
