No login prompt on console Ubuntu 20.04.3 LTS (running on qemu Synology)

it flag

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.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
