Ubuntu liveboot issues with graphics

etcetera · 05-07-2023, 05:41 PM

The Ubuntu server refuses to be made into a liveboot. When I boot off the flash drive, it goes into the install process.
Only the "desktop" download works as a liveboot. Am I doing something wrong or what?

Secondly, about the "Desktop" download. It does boot but the only boot option I see is "Graphics-safe". So it boots without any drivers at all. The resolution is obnoxious. The native laptop resolution is 1080, there is no way to adjust it to 1080.
Also there is an external 4K monitor (that it doesn't even see).

if you can interupt the boot loader and edit the "linux" line... add vga=794 will give you smaller text.

That's all I got.

No, as per your other thread the server ISO is only an installer not a live version.

I just tried running 22.04 live in a VM and I saw all of the boot options i.e. try or install, safe graphics, OEM install and test memory. What version are you running and did you verify the downloaded file's checksum?

I downloaded whatever is latest-greatest "desktop" is currently there.

I too see:
try or install, safe graphics, OEM install and test memory.

What is this safe graphics stuff? I want to run a fully functional edition. If Ubuntu can't do it, will try another distro, this is unacceptable.

As far as I know the only difference between "try or install" and "safe graphics" is the latter adds nomodeset as a kernel boot parameter which turns of KMS. It disables the kernel from loading the video drivers. Have you tried selecting and boot "try or install"?
