Ubuntu 10.10 - Unable to blacklist some modules

If I recall correctly, those modules have dashes (-) rather than underscores (_) in their names. If that's true, then the names you've blacklisted aren't actually the names of the modules.

If that advice doesn't help, please post the output of the lsmod command.

It doesn't matter. lsmod shows them as underscore.

$ cat /etc/modprobe.d/blacklist-greg.conf
blacklist ir-rc6-decoder
blacklist ir-rc5-decoder
blacklist rc-rc6-mce

"It doesn't matter. lsmod shows them as underscore."

Indeed, you're quite right. It turns out that what I thought I was remembering, I was in fact remembering about something else altogether.

I'll try to look into this further, but I'm leaving the question open as perhaps someone else will be able to help you before I get around to doing so.

andy@D420:~$ sudo modprobe ir
ircomm irda-usb ir-kbd-i2c ir-nec-decoder ir-rc5-sz-decoder irtty-sir
ircomm-tty iris irlan irnet ir-rc6-decoder ir-usb
irda ir-jvc-decoder ir-lirc-codec ir-rc5-decoder ir-sony-decoder

They are minuses. Perhaps the fact you have them blacklisted in TWO files may be an issue. You could work around this with:

gksudo gedit /etc/rc.local

and add:

rmmod ir-rc6-decoder
rmmod ir-rc5-decoder
rmmod rc-rc6-mce

ABOVE the 'exit 0' line and reboot, may help

I've tried underscores and dashes (minus signs). Neither work.

While doing rmmod is an workaround, blacklisting should work. I'm guessing somewhere modprobe is being called with the -b option, but I have no idea what script that would be in. A search of /etc and /usr/share didn't turn it up.

It looks like the modules are forcefully loaded in the kernel LIRC driver. On line 347 of linux-2.6.38/drivers/media/rc/ir-raw.c is a init_decoders() function that loads all the modules into the kernel.

This makes me think that we need to disable the keyboard emulation some other way. I'll keep looking.

Thanks Chris B, that solved my question.
