General system Newbie

blacklist <kernel_module> at etc/modprobe.d/blacklist.conf
is not working. I’m using eos with systemd boot. Any suggestions?

What shows: cat /etc/modprobe.d/blacklist.conf ?

It would be nice if your post was more descriptive. What module are you trying to blacklist and for what reason?

So you should be trying to blacklist rtw88_8821ce?

Edit:

sudo nano /etc/modprobe.d/blacklist.conf

add

blacklist rtw88_8821ce

ctrl + o then enter to save
ctrl + x to exit nano

reboot

Edit: Or which ever module you are trying to blacklist.

Thanks
