No login prompt on console Ubuntu 20.04.3 LTS (running on qemu Synology)
By Andrew Adams •
With one of the last Ubuntu updates I can't login on console anymore, because I'm getting no login prompt.
I'm running Ubuntu 20.04.3 LTS on a Synology Virtual Machine and try to connect to the console via the web interface. I only see some kernel messages.
I tried to press Ctrl+Alt+F1 / Ctrl+F1, but no success. I guess the web interface doesn't send these special key combination correctly.
Any ideas?
These are the last kernel messages. I would expect some logging about services and finally the login prompt, but nothing happens after the blacklist message.

I fixed it by adding nomodeset to the grub default command line.
cat /etc/default/grub|grep nomodeset
GRUB_CMDLINE_LINUX_DEFAULT="quiet text nomodeset"Executed update-grub afterwards and rebooted.
