Please try the hotkey "Alt+PrintScreen+x", then reload rtl8822be?

Hi, not sure what the hotkey was supposed to do if anything, I don't have any dmesg entries after executing it and there's no change in the status of the r8822be module when I attempt a modprobe afterwards.

Ok, can you test if disabling secure boot in BIOS helps?

dmesg output secureboot disabled Edit (71.8 KiB, text/plain)

Yep, disabling Secure Boot seems to allow the driver to load no problem.
Attached is dmesg output of this boot sequence with Secure Boot disabled.

Thanks for your testing.

This means staging drivers don't work when kernel lockdown is enabled. I'll discuss with kernel team members how to sort this out.

Hey,

Still seems to be an issue with Kernel v4.18.0-13 too. Tried to modprobe r8822be module and received the same "operation not permitted" error as before.

Installed 18.04 LTS with kernel 4.15 - was required to disabled secure boot mode to get the r8822be wifi module working. Seems unsigned here as well.

So, the driver was previously unsigned, then signed and included in the original Ubuntu kernel for 18.10, then subsequently unsigned during an update somewhere along the way?

That doesn't make sense to me - would have to try and find upstream to work out what has happened.
Larry Finger suggests that Realtek has rewritten the driver and his GitHub repo is only for older kernels that do not already ship the r8822be driver. 4.21 is quoted as when this new driver will drop.

The drivers in staging won't get loaded when lockdown is enabled to provide safety. There's a list to override behavior though.

The r8822be in its current form defaults to enable debugfs, which can be less secure as it exposes and extra interface to userspace. But we are not sure if the driver still works once the debugfs gets disabled, so please test this kernel:
https://people.canonical.com/~khfeng/lp1806472/

Once we are sure r8822be still works when debugfs is disabled, we can include this fix to Cosmic.

Hey,

This kernel seems to be working fine on a fresh install of KDE Neon (based on Bionic). I had to roll back due to other reasons, but installing this kernel has fixed it for me here. If you require any logs let me know.

Short of reinstalling to 18.10 I haven't got a way to test it on there, unfortunately.

Hopefully it won't break when Realtek releases the rewritten driver :)

Didn't test this on a full install but enabled the 4.18.0-16 signed kernel through the cosmic-proposed repository on a Bionic install. Works fine! mokutil reports secure-boot enabled and release shows as 4.18.0-16 :)

It should be noted that just installing this kernel itself did not fix the issue, the kernel-modules-extra package must be installed!

Thanks.
