ima: No TPM chip found, activating TPM-bypass!
Dear All,
My HP Envy x360 laptop has TPM2.0, which was working with Windows 10 previously. I recently installed Kubuntu 22.10 and it is not working. I have installed the relevant tpm packages and tools. But there is no /dev/tpm0 for example.
How can I make it work??
sudo dmesg | grep -i tpm:
