Cannot run in framebuffer mode. Please specify busIDs for all framebuffer devices, with regard to X-windows. How do you specify a busID? Occurs in latest LTS release (22.04).

  • Are there any error messages that can help with debugging? Either printed to the console, the output of tail -f /var/log/messages, or sudo dmesg? – moo Jan 15 '24 at 20:27

  • Edit your original question and add all the info. Sounds like you have a problem with your X config. You could try: sudo dpkg-reconfigure xserver-xorg – moo Jan 16 '24 at 06:18
