In 'KSysGuard' process table I see a few dogs named watchdog/someNumber and watchdogd and as far as I've known, these dogs do some interactive job on a remote system where there's no human operator. As I do use this system by my own, I think, I don't need these dogs. I've tried to kick out these dogs in following two way:

1) added

Code: Select all

kernel.nmi_watchdog=0

at the end of /etc/sysctl.conf BUT they came back after reboot. So, I'd removed that line from /etc/sysctl.conf and

2) added kernel.nmi_watchdog=0 in /etc/default/grub like this:

Code: Select all

GRUB_CMDLINE_LINUX_DEFAULT="quiet nmi_watchdog=0 splash"

saved it, ran

Code: Select all

sudo update-grub
reboot


on 'Konsole' BUT they came back after the reboot.

How can I get rid of these dogs?

reading a bit about the linux kernel watchdog, it is entirely harmless and can generally be ignored (it's not like any remote system is watching your system; it's just the kernel trying to detect problems in a running system that require a reboot). I'm skeptical if there is any benefit to removing them to make the hassle of removing them worthwhile.

If you are insistent that they be removed, I would recommend you do some more research on the watchdog process and how to properly remove it (which shouldn't be at all specific to any desktop or even linux distro).

I'm not exactly sure what it is related to actually BUT by the numbers attached to watchdog it's obvious that each watchdog is monitoring a core of my processor. I've watchdog 0-7 because it's 8 logical cores and watchdogd is probably the parent of all those watchdogs.

If my system were a server and I left it in a remote location to do it's job by it's own, then these watchdogs interactive jobs make sense BUT for my personal computer, which is being monitored by me constantly as long as it is turned on, these watchdogs are additional overhead to my system, I can do a hard/soft reboot by my own if necessary.

I haven't yet found any article to disable these permanently! It wouldn't bother me that much if they named it in a good way, I'm allergic to dog! Dolphin, powerdevil are also a kind of weird name, KDE team should get rid of such weird naming conventions to respect it's users. We don't like to deal with devil or dolphin or any sort of animal for official purpose.

On Arch with KDE Plasma 5.16.3, I don't have watchdog/0-7, there's only one watchdogd. Feels like, Arch with Plasma is much lighter than Ubuntu based KDE Neon, lot less initialized process. KDE Team could make a installer package with Arch for its users. Installing Arch from Archers' repository is really a PITA. Archers probably still live in a Windows 3.1 era!

I think, I'll be with Arch and Plasma instead of Ubuntu based KDE Neon!

Maybe it is something that adds as you do more with your system perhaps, or the specific timer hardware on a motherboard? I only have one watchdogd process running on my Neon 8-core system, as well as on my older Kubuntu system with a 4-core cpu.

also, #3 here worked for me to disable it.

I did the same on KDE Neon as you can see in the original post BUT it didn't work for me!

Mine is HP Pavilion Notebook with Intel core i7, Intel HD 530 and NVIDIA 950M Optimus. I haven't yet installed linux on my AMD Quadcore Desktop with Radeon.

See those watchdog/0-7 of Ubuntu-based KDE Neon here https://unix.stackexchange.com/questions/528929/what-are-these-watchdogs

I haven't yet found solution to disable the last watchdogd in Arch with KDE Plasma but I've a lot less default processes. With Ubuntu-based KDE Neon, my laptop started with more than 200 processes by default, as far as i remember the number was 212 whereas in Arch with Plasma I've only 175, no ssh-agent, no avahi, no watchdog/0-7, etc. and NVIDIA works really well and very easy to install, I just have to do a:

Code: Select all

pacman -S bumblebee mesa nvidia
reboot

I don't have to do a prime-select and logout to switch, apps like obs studio automatically use nvenc if I select hardware acceleration in obs settings.

The linux kernel watchdog is completely innocuous and can typically be ignored, according to Dog Dude (it's not like a distant system is watching your system; all it's doing is trying to identify issues that call for a reboot in a running system). If there is an advantage to getting rid of them that justifies the trouble, I'm dubious.

Suppose "we" is you and your alterego. Guess you'll need a defibrillator, some clozapine and xanax if you stumble on the Deadbeef player. But hey, feel free to name them whatever you like and stay away from ubuntu. Those guys are sooooo anti vegan.
