Login screen not displayed

[JulesJacobs]

When I boot up the computer I am shown a dark grey screen with a mouse cursor, but nothing else. When I short press the power button I see a menu that allows me to power off the computer. When I reboot the computer several times, I am able to get the login screen and use the computer. I would like to have it so that it always shows the login screen, without having to reboot several times. Do you know how to fix this issue? I am using Ubuntu 24.04 LTS.

Something is broken.
What is "the computer". Spec?
Try LiveUSB again. Do you see same problem?

Thanks. The usb boots up and works well, and it does not have this problem, but I don't get a login screen there. Spec is Ryzen 7950X with RTX 4090 graphics card, so the specs should be good enough to run, I think. Is there any other information I can provide that may be relevant? Ubuntu is very fast when I am able to log in.

If you are using Ubuntu 24.04 can you run this command (as a starter for one just to gauge what you have in booting up) ...

efibootmgr

Running this command produces the following output:

~$ efibootmgr

I'm hoping that others chips in since I see nothing amiss there. You have a pulse.
Now if it were me I would install rEFInd since I'm very comfortable with it.
It sits as a neighbour in \boot\EFI\refind .. alongside \boot\EFI\ubuntu\
and you go into BIOS at boot to set it as choice.
But it might be BIOS update needed at a guess.

Just to add to dragonfly41's suggestion on rEFInd, it's worthwhile to install it.
Grub is always the boot-loader and rEFInd is a boot-manager.

RTX 4090 graphics card,

Does it help to try a different driver for this Nvidia graphics card?
