I got problem after running software manage update. My second monitor not detected and never wakes up. after long search (Knowing that i am a new Ubunutu user) found that NVIDIA drivers do not load on startup because of that security boot is enabled. When I disable security boot NVIDIA drivers load on startup and my second monitor works fine.
Before the update i had never problems like this and i had my security boot always enabled.
I have read also that there were some fixes on waiting for confirmation so i waited and I have installed last updates from Ubuntu. unfortunately my second monitor still does not work if my security boot is enabled.
Is there something i can do? I have tried a lot of things that i found on several sites. Unfortunately nothing worked.
Thanks in advance!
some info:
$ nvidia-smi
NVIDIA-SMI has failed because it couldn't communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running.
$ sudo modprobe nvidia
modprobe: ERROR: could not insert 'nvidia': Key was rejected by service
