Ubuntu 22.04 missing framebuffer /dev/fb0
I have a Rapsberry Pi4 with kernel 5.15.0-1035-raspi and installed Ubuntu 22.04 server 64bit (aarch64) (headless).
I install teamviewer-host as described in: https://community.teamviewer.com/English/kb/articles/6318-install-teamviewer-classic-on-linux
During installation I get the message: "The framebuffer console seems to be unavailable or has the wrong format. Please make sure that /dev/fb0 is accessible and it is configured to 32-bit depth."
The teamviewer-host service runs without errors. On my remote system I see that the teamviewer-host is online. Set up a connection failed with the error "Partner did not connect to router".
I try to solve with the sollution in post https://community.teamviewer.com/English/kb/articles/109391-fix-connectivity-issues-partner-did-not-connect-to-router
The problem is that the system is headless and missing the monitor /dev/fb0.
So i want make a virtual frame buffer as described in https://community.teamviewer.com/English/kb/articles/4352-install-teamviewer-classic-on-linux-without-graphical-user-interface
It doesn't work. I don't get the /dev/fb0. Could someone help me out?
When I connect a physical monitor I see /dev/fb0 and it is possible to set up a teamviewer session.
