I have the same problem trying to install Ubuntu 24.04 on this hardware:
- Gigabyte TRX50 AI TOP
- Threadripper Pro 7965WX
- RTX 5080
All install variants from USB stick end in an immediate black screen
- “Above 4G decoding” is “ON”
- “Re-Size BAR Support” is “OFF”
Is there anything else I can try?
