Hello,

at first I am sorry for any English mistakes. If something is wrong, please correct me.

Now my problem:
I installed a RTL8723BE driver ( https://github.com/lwfinger/rtlwifi_new ) on KDE Neon 5.8.7. If Secure Boot is disabled, everything works fine. If not, the driver is not loaded. Thus I tried to sign it:

Code: Select all

cat << EOF > configuration_file.config
[ req ]
default_bits = 4096
distinguished_name = req_distinguished_name
prompt = no
string_mask = utf8only
x509_extensions = myexts

[ req_distinguished_name ]
O = Organization
CN = Organization signing key
emailAddress = E-mail address

[ myexts ]
basicConstraints=critical,CA:FALSE
keyUsage=digitalSignature
subjectKeyIdentifier=hash
authorityKeyIdentifier=keyid
EOF
openssl req -x509 -new -nodes -utf8 -sha256 -days 36500 -batch -config configuration_file.config -outform DER -out public_key.der -keyout private_key.priv
mokutil --import my_signing_key_pub.der

REBOOT

sudo /usr/src/linux-headers-$(uname -r)/scripts/sign-file sha256 private_key.priv public_key.der rtlwifi.ko
sudo /usr/src/linux-headers-$(uname -r)/scripts/sign-file sha256 private_key.priv public_key.der /lib/modules/$(uname -r)/kernel/drivers/net/wireless/realtek/rtlwifi/rtl8723be/rtl8723be.ko


However, it still is not working.
What did I wrong? Why is it not working?

Thank you!

Topic can be closed. I solved the problem.
I signed all dependences and the firmware and it works fine.
