How do I disable the “lp” kernel module permanently

Question

How do I disable autoload of the lp kernel module?

What I've tried so far:

• Try to disabel the module via blacklist

  echo "blacklist lp">>/etc/modprobe.d/blacklist
  echo "blacklist lp">>/etc/modprobe.d/blacklist.conf
  

• Recreated the linux image

  sudo dpkg-reconfigure linux-image-$(uname -r)
  

Even after reboot, the module was loaded again.

Brute force rm /lib/modules/$(uname -r)/kernel/drivers/char/lp.ko is working fine, but looks ugly to me ;)

Answer 1

your brute force solution is fine in my books :) try lsmod when the module is loaded and see if there is anything in the used by column, there is a chance another module loads it as a dependency
