Unable to set up Ubuntu 22.04 LTS on Threadripper 5955WX
This resolved the OS installation without using the GPU. I used the command 'nomodeset pci=noaer' during setup, which allowed me to install the OS and then permanently added it to GRUB's configuration. However, when connecting a single GPU on the MOBO, I still encounter issues—just a black screen and no response, even though NumLock is enabled. Disconnecting the GPU causes the system to boot into Ubuntu 24.04 LTS.
This permanently disables the GPU kernel module, preventing it from functioning. It’s just a temporary fix to install the system. You need to update the latest NVIDIA driver, delete this line, and check if it resolves the issue.
The Grub line isn't preventing any kernel module from loading. Noaer disables advanced error reporting, which stops the kernel from attempting complex video settings and keeps it in the default BIOS mode. Your confusion about the GPU is understandable—removing it should stop booting with video support, but you need to confirm where the video source comes from.
I receive video output from the motherboard's BMC/ASMedia subsystem, not directly from the CPU. This board enables BIOS access, remote management through iKVM, even without a GPU installed. I successfully installed Windows 11 Pro using a single GPU setup, and it functioned stably. Initially there were some issues, but they turned out to be related to the drive.
It seems to function on Windows, so the hardware appears okay. You were mixing it up with another choice... Connecting the monitor straight to the GPU might help.
Yes, you can boot using a monitor linked to both the dGPU and the BMC simultaneously. The UEFI interface will display on either output, and GRUB will appear on one or both displays depending on your setup. After the kernel launches, the system will initialize accordingly.
