You don't seem to have a kernel driver loaded for the Nvidia GPU, so any ports attached to that GPU (like HDMI usually is) won't be usable.
This can happen if the Nvidia driver was installed and compiled for the old kernel version but somehow failed to rebuilt for the new kernel version. Please try using the 'Additional Drivers' app to reinstall the Nvidia driver and tell us what version it is. ** Package changed: xorg (Ubuntu) => nvidia-graphics-drivers (Ubuntu) ** Changed in: nvidia-graphics-drivers (Ubuntu) Status: New => Incomplete ** Summary changed: - External Monitor No Longer detected + [nvidia] External Monitor No Longer detected -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1897189 Title: [nvidia] External Monitor No Longer detected Status in nvidia-graphics-drivers package in Ubuntu: Incomplete Bug description: I noticed that a new kernel was available and booted into it today, after booting previous issues (display font size on login, and laptop touchpad/trackpoint not working) were resolved. However, my external monitor no longer displays in the settings, and can't appear to be used. I suspect the kernel update coincides with an nvidia driver update, but haven't looked into that yet.
