Those appear to be hardware related. They might not be important.
Presumably the same issues were found while booting the installer, yet you managed to install.
I’m guessing that you have a different problem, perhaps related to using nvidia graphics.
When you see the boot menu, select the Tumbleweed entry, but then type ‘e’.
That should bring up an editor to edit the boot command. Scroll down to find the first line that begins with “linux” or “linuxefi”. Hit the END key to get to the end of that line. Append “nomodeset” (without the quotes, but with a space separating that from what comes before.
The use CTRL-X to resume booting.
This intended as a test. If it boots up this way, you will probably need to install nvidia drivers or make other changes.
I set the “nomodeset” and it booted with very low resolution. Regardless, I managed to add the nvidia proprietary repository and install the driver.
I rebooted and now it doesn’t do anything again, even with “nomodeset” like you said.
If I press Ctrl + C when it hangs up after a while, it will clear the screen and start flickering endlessly
