[DESKTOP] Please tell me Kubuntu has something equal or better to what Win 7 'services' had ?

[sparxz]

So I have been experimenting with Kubuntu now for some weeks,
and installed software that runs backround services.

I have noticed some strange omissions from the system. I have searched on-line for answers,
and cannot find them.

How do I manage services in a GUI, in the way eg SUSE, Windows & TrueOS allow ?

I am now overrun with services now, system is cripling, that I can only kill-stop from the command-line slowly, one at a time.

When I type in "services" into KDE menu search, I see "backround services", which shows up a VERY basic list
of "start up on demand" and "start up services". from Ksysguard, & htop, it is obvious most of the services
are not in said listed "backround services" utililty. Eg Postgres running.

There are also a number of USB devices I cannot get working, because of not being able to find or enable right service,
eg Kernel etc.

Microsoft windows7, had a much more acessable method of listing/accessing and controlling 'services'.,
including granularity with stoping restarts, and delays.

Please tell me Kubuntu has something equal or better to what Win 7 had ?

I wish there were sets of system profiles I could use, when needed, and have optimal use of resources.

Thanks

Install kde-config-systemd
That will add a Systemd GUI to System Settings, at the bottom of that GUI.
Open it. In the drop down combo box showing "All" change it to "Services". Right mouse on a service to bring up a dialog. You will have several options.

A service that is masked (has 0 bytes) is prevented from starting at boot up. To unmask a service use
systemctl unmask name.service

Here is a somewhat dated but mostly applicable rundown on systemd operations:

Got it. Thanks.
Why on earth would that not be available by default ?
Even Micro$oft Windoze did not obsure this level of feature from users !

systemctl is running at much too low/weak a cpu priority. "normal" is not enough, to pull out of an unstable system situation.

I am having to kill enough services in the terminal just to get a glympse of it, as it stuggles to load and display.
Cannot get any R-click to work.
An ironic, disapointing and self defeating set up.

I hope Kubuntu team 'rethink' this resource management and adimin access strategy.

Thanks again.

This is not a Kubuntu specific thing here, this is pretty standard across most Linux variants. We use the same underlying system as Ubuntu, which in turn based on Debian's. What is different is that there are, upon first glance, a LOT of 'services' running, though if you really look into it, there are many in number compared to a Windows system, perhaps, but they are much smaller.

Why there is no graphical front end to to control these services? Likely the very low demand for one, or rather a very low perceived need for one. As a general purpose desktop focused distro, there is not as much a need for such tools by default, though they are available. I think Suse is the only one that really focuses on a GUI for system administration, while all the rest, including Red Hat (iirc) focus on the command line. If there was any sort of real demand or need for it, I imagine there would be more GUI tools available for these tasks.


If I might ask, which processes or services are crippling your system?

Kubuntu normally comes with eight loops, loop0 through loop7. You have 108 loops active and each has a niceness of -20, giving them highest priority! Why? What are you doing with them?

I used to use PostgreSQL in client-server app development and I never had as many Postgres processes running as you have. Are you running more than one instance?

Also, when you post something as long as the output to your top command place it between [ quote ] and [ / quote ] (spaces removed), If you want to preserve formatting then use [ code ] and [ / code ]. In the icon panel above the reply text box are two icons on the right: quote and code (#).

My guess is that he has his DE session set to restore previous, which would open those previous loops, as well as the eight that get started, incrementing the number of such instances every time he reloads his DE. Just a thought.

So, what is bogging you down? You are running a fair bit of web server software, php, plus a database, a media server, a third party web based snap management tool, an enterprise level backup system, a remote management tool (dotmoz), blueman (which is Gtk, and redundant in Plasma) and hence some quite a few Gnome services (probably unneeded, dunno how they became installed)....and I got tired of looking after that. A lot of stuff, and with a bunch of Gnome specific services probably pulled in by whatever bits of gnome you installed, or have added Kubuntu to an existing Ubuntu Gnome (or vice versa)

However, your system does not seem to be too overly taxed, considering the load.
Ksysguard is the included GUI system monitor, it is often more useful than top, or the prettier Htop, for quick peeks at what is going on, and grouping processes by parent threads can give a better picture of what task is drinking all the juice.

What I do notice is that you are showing swap usage, which is a peculiarity that Ubuntu based distros sometimes suffer from. There is a setting called swappiness, that in its default settings makes the system go to swap far too soon, which of course is slowing down your hard drive a lot.

You can adjust this
https://help.ubuntu.com/community/Sw...I_change_it.3F
I suggest setting it to 10. Setting it to zero does not disable swap, so even going down to that is possible. Luckily, it can be changed (temporarily) on the fly so testing is pretty simple.


On a side note, all those entries with loopX as the naame are related to snaps, tho if you notice they are not using much, if anything, until something is run. I imagine that uis a LOT of snaps you have there

Hi I was trying to set up Postgres and other services to learn. My experiments seem to have gone badly wrong. I was hoping to use and learn mostly from the GUI admin console "pgAdmin III" Not sure how I set so many instances of Postgres, I only wanted one !! "pgAdmin III" dost not list any postgres server groups running. Any ideas, how I could tame to have even one that works, and to learn from ? As is, as I have a heavily multi-service loaded system, on a desktop system I need for other things too !

I am trying the mentioned:
sudo sysctl vm.swappiness=10for a bit of light relief !

In all the promotion of SNAPS on so many Jupitar broadcasts shows, they never mentioned any downside.
I thought it was an install container method, and did not know it had to run each as persistant stacked seperate multi-services.

Thanks.

Snaps are run in separate 'containers', so each one has its own virtual mount point, and each one looks to have its own process running,though for you the vast majority are using minimal, if any, resources when you aren't using them.

Snaps by default I believe keeps three versions of each application, so that is still a huge number of packages you seem to have. Because the processes are tied to the snap mount point, I don't think that the restoring of previous desktop sessions is the cause of the number here.

Snaps do not necessarily create extra, duplicate system services to run, as they do make use of what you already have. The main downside is the duplication of some system library files a snap may use internally that one may already have on their system but may not be on someone else's, so they use more disk space.

The number of postgres threads could be due to having a mulitcore processor, if you sort processes by parent you may see that this is the case for some things. I also think that each different sysmon shows processes differently than other tools; I always have more there it seems than when I look at Ksysguard.

I think you might try using virtualbox to set up a separate OS with a limited ram and cpu usage set up, running a minimal OS (Lubuntu or even Ubuntu Server), else ditch all the web based,php/html/gui admin bits that are the real culprits here. You have not stated what sorts of snaps you are using, not specifically, but if it is all this database and web stuff, maybe install them the normal way? Not sure if that saves any juice or not, though.

[sparxz]

Hi,
Yes, I tried many things. VM & local PHP stuff.

I have only recently learned about SNAPS, and now seeing the downside.

It will take time to untangle it all, on a AMD duel core 3Ghz, 12GB system.

Thanks

IF, perchance, you decide to do a re-install to "untangle it all" allow me to suggest that at the beginning of the disk partition phase that you choose manual, create just one partition, sda1, and select Btrfs as the / partition. Then, when ever you want to experiment with something you can take a minute to create btrfs snapshots of @ and @home beforehand. That way, if things don't work out, you are only a 3 to 5 minutes away from restoring your system to what it was before your experimentation.

Hi,

I used to do that with OpenSUSE(Seperate partition for OS, & seperate Partition for home), for many years, which SUSE
who were the first to offer, used to suggest that be default. When ever I would trash the OS, I would have a perserved 'home'
When I recently setup Kubuntu, I mainly went with defaults. Suprised it followed the Windows convention (OS & Home in one partition)!

I was tempted to use BTRFS, but after hearing about recent issues with it, I played safe & went with EXT4.

I dipped my toe into TrueOS, and would prefer to use OpenZFS as main storage.
BSD is far behind Linux on ease of install. Access to a file system OpenZFS seems to be a motivation
for people to choose BSDs over Linux. When ZFS is made more available from eg GPartion & MiniTools & Partion Magic etc,
I can see it over talking all other Filesystems that need modest file access speed,
Perhaps a really fast file system will be developed 'just' for running an OS. Could be so lean as to only run in Memory !

Thanks

I’ve been using Btrfs for about three years in a variety of configurations on both spinning and SSD’s and haven’t encountered a single problem. That’s probably because I follow the recommendations of the Btrfs dev’s about the number of snapshots per subvolume, the use of defrag, scrub and balance, etc. Too many people are too quick to blame the software for their own foolishness and lack of foresight.

Before any experiments, which I frequently try, or upgrades or installs I always take a snapshot of @ and @home. After experiments I always roll back. If the upgrades go south, which they rarely do, or if I don’t like an install, I roll back. The only time I had to do a reinstall was when I switched to Neon for a few years, and again when I switched back to Kubuntu.

I’ve run RAID1, RAID0, single, duel, ... all the combos possible with three internal HDs, except RAID5 or 6. Nary a problem switching between them, all while using my system live.

During these two switches copying my data from a snapshot of Home made the switch trivial.

ZFS is not yet offered as a root filesystem during installation, as Btrfs is, and Btrfs does not need an EXT4 Boot Partition, making backups more complicated the way ZFS does.
ZFS needs more RAM than Btrfs. Btrfs snapshotting is more flexible than ZFS’s.
Btrfs is less complicated and easier to use than ZFS.
