raspberry pi / leap 15.4 / blacklisting modules
by Per Jessen 05 Apr '23

05 Apr '23

Context - I have a Raspi (raspi1) running Leap 15.0, controlling some SK6812 LEDs. Has been working very well since 15.0, but I thought it was probably time to consider an upgrade. I have a 2nd Raspi (raspi2) now running 15.4. I am having trouble getting access to the GPIO I need, and I noticed that 15.4 has a lot more miscellaneous modules being loaded. I don't seem to be able to prevent loading modules with this: /etc/modprobe.d/99-local.conf blacklist this-or-that In my limited understanding, this ought to prevent this-or-that from being loaded, but it doesn't. Any thoughts? -- Per Jessen, Zürich (6.3°C) Member, openSUSE Heroes (2016 - present) We're hiring - https://en.opensuse.org/openSUSE:Heroes

No. The resolv file lives in ram, in a tmpfs. Something creates it on every boot. What? Never mind what. If you use this recipe to disable the "what", then you can delete the symlink to /var/run/netconfig/resolv.conf. Then make /etc/resolv.conf an ordinary file (sorry, I did forget to mention these steps), and the system will leave it alone, and it will persist between boots. -- Bob

It supposed to be root:linux, but that doesn't work. Any ideas ? -- Per Jessen, Zürich (11.4°C) Member, openSUSE Heroes (2016 - present) We're hiring - https://en.opensuse.org/openSUSE:Heroes

There are also times when modules are loaded unnecessarily. I think even the 2.2 series kernel had more than four or five modules :-) Much will depend on what you do with your Linux systems, how many you have and how varied they are. How much you dabble with the hardware. -- Per Jessen, Zürich (15.7°C) Member, openSUSE Heroes (2016 - present) We're hiring - https://en.opensuse.org/openSUSE:Heroes

[oS-en] Hardware "bug" on Lenovo L14 Gen 3 AMD laptop.

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 When the machine is sleeping 8aka suspend to ram), if I connect or disconnect the mains, the machine awakes, even if the lid is closed (Leap 15.5). Andrei posted some reading material that mentioned inhibiting some events from waking the machine, so I definitely have to explore that. But just mentioning the issue here so it is known. - -- Cheers Carlos E. R.

I have been in most of them. No, I have totally missed that. I thought you were talking about having to create initrds manually. For the last couple of years, I have not been in a single situation where I _had_ to run mkinitrd. dracut was very useful though. -- Per Jessen, Zürich (16.2°C) Member, openSUSE Heroes (2016 - present) We're hiring - https://en.opensuse.org/openSUSE:Heroes
