After a fresh install of Kubuntu 18.04.1, my system is not booting at all. After Bios screen, all I get is a white cursor in a black screen. Before installing this version, I was using a working Kubuntu 14.04. What I have tried so far :
- Install with Normal/Minimal installation
- Enable/disable "Download updates" and "Install 3rd party software" at installation
- Use disk partitions as they were before with Kubuntu 14.04 :
- one 512Mb fat32 partition at start of the disk for booting (EFI)
- the rest of the disk as an ext4 partition for /
- Wipe out entire disk an use recommended setup (with creates the same setup)
- Use custom disk setup (one single ext4fs partition for /)
- At BIOS boot setup, boot as UEFI
- At BIOS boot setup, boot as Legacy
- Change BIOS settings to use Secure Boot
What I haven't tried yet :
- Installing another flavour of Ubuntu (I don't believe it will change anything)
- Installing an older version of Ubuntu (the whole point in reinstalling was to update)
- Installing another distribution (I would like to stick with Ubuntu)
- Manually installing GRUB from LiveUSB system
I am not even having the Kubuntu logo, so I suppose the issue isn't with graphics drivers. I am unsure if the problem is with BIOS setup (UEFI/Legacy/Secure boot/etc...) or with Ubuntu itself.
- On one hand, the black screen without any other information straight after BIOS logo suggests that BIOS isn't even finding where to boot the system
- On the other hand, I already tried different boot modes and previous version of Ubuntu booted fine with the same setup. Also, I have a dual boot Windows that is working fine (I force to boot on the other HD via Bios Boot menu).
I am using an Nvidia graphics card, GTX 1080. It required some manual setup to work on 14.04 but I suppose it should work out-of-the-box in 18.04.1 as it is not as new anymore. And my issue doesn't seem graphics-related as I don't get any output.
Any clues on what is happening?
