I've just purchased a brand new computer and tried to install Ubuntu 20.04, but it only boots in safe graphics mode, and after installation, I get a black screen. When I go for 21.04, everything works fine, but I'd prefer the LTS version for obvious reasons.
Hardware details: Processor: Intel Core i5 10400 with onboard graphics, motherboard: Gigabyte Z590 GAMING X
Am I doing something wrong or is that hardware not supported by 20.04?
(I'm a hardware and linux noob)
