Hello Im new to KDE Neon and KDE in General. Ive used Ubuntu and Mint in the past but now I want to try something new and KDE seems pretty promising.

But sadly, I have a problem in the installation process.
The Installer goes to a blackscreen after I selected KDE Neon in the GRUB menu.

Ive downloaded the latest User release (neon-useredition-20170608-2351-amd64), checked the sha256sum, created a boot USB. Ive also tried the stick on another computer. All fine.

But if I try to use the USB on the PC I want to install it on it doesn't work. I only come to the GRUB menu and can select Neon to boot, after that the KDE Neon symbol (without the version number) shows up for a second and then a blackscreen remains. I also cant select the tty terminal.

Thanks in advance.

KDE Neon loads normally for me, but I've had this problem with other Ubuntu-based live CDs/USB sticks.

The problem was exactly that it was using the wrong terminal by default.

Did you try all F keys? ctrl + alt + F1, then ctrl + alt +F2 etc.

@anewuser I can go into any tty by using the proper keys. My issue is: my machine (sometimes) goes into tty1 without prompting it to do so. Please join dedicated thread and tell us your opinion. Thank you. viewtopic.php?f=309&t=140648 Yes, I am on User 5.10.1

I've tried every tty, none of them work. The keyboard doesn't even response (indicator LEDs doesn't light up) during that black screen.
I can't shut down the PC during the blackscreen, so im forced to use the CMOS reset.

I can add to my description that I installed Windows 10 right before the KDE Neon on the PC. I want to have a dual boot on that machine.
I also tried other Linux distros with a USB and a live CD (Ubuntu, Mint, PartedMagic) and they worked flawlessly.

I can assure you: no distro on this planet works flawlessly. Might not have this particular flaw but have other flaws. That being said, this tty issue is strange. It really gets to me. Too bad I can't screenshoot tty1 to tty6 working on my machine (User 5.10.1). Obviously, I'm in no disbelief of what you're saying.

I had same problem.

"Catch" grub menu, press E to modify boot parameters . FInd and remove two words:

quiet splash

If KDE boots correctly, modify grub.
Edit file /etc/default/grub
(sudo required)

replace: GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
with: GRUB_CMDLINE_LINUX_DEFAULT=""

now run:
sudo update-grub2

At the grub menu press "E" and i put "nomodeset" between quiet and splash that sorted it for me. I think if you goto advanced options at the grub menu theres some kind of graphics failsafe option too. KDE has some major problems for me during installation finding the right videomode with a newer nvidia card

I was able to solve this issue on my machine.

I updated Kernel from version 4.8 to 4.10.
