sgx disabled by bios
This is a newer warning due to a kernel upgrade.
It allows the linux kernel to interact with CPU security features developed by intel.
The message does not harm anything
You can either:
- ignore it
- make a change in the bios to enable the feature.
- the cpu may be capable and the bios not.
- If you can't find the "switch" in the bios then:
- Your motherboard cannot use sgx
- Your BIOS is too old.
- If after all you determine your hardware cannot use sgx then you can hide it
- add nosgx as a boot parameter.
- In the file /etc/default/grub you add nosgx in the follwoing section
- GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nosgx"
- sudo update-grub
- reboot and you will no longer see the error message.
- In the file /etc/default/grub you add nosgx in the follwoing section
Boot Errors
Since upgradeing to 22.04 there are lots of acpi errors that appear during boot and once in a while prevent a clean boot.
Open the files /etc/default/grub
add loglevel=3 to ignore those errors.
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash loglevel=3"
Will not shutdown completely
You can first test to see by doing a complete shutdown with the command
sudo shutdown -h now
If that completes then look further.
