Anything showing in system monitor?


#22

As the name says, it manages your modem (if you have one). It’s related to NetworkManager.

If you do not have a modem, you can safely remove/mask/disable it.


#23

Nothing. It looks all normal on the system monitor, at least on the graphical widget that I can add to the panel.


#24

Try htop in a terminal, keep it running (yakuake is good for this).


#25

Alright. Will do.


#26

I have htop running now. What’s yakuake?


#27

Plasma’s drop down terminal, press F12 (the default) to show it. You may need to install and add to startup as you added Plasma to existing install.


#28

F12 at desktop doesn’t do anything.
You mean Konsole isn’t the Plasma terminal?


#29

you can also remove akonadi and pim suite if you dont use it


#30

Install it… It is based on konsole, but is a quake style dropdown terminal.


#31

Just had htop and the GUI Task Manager running at the same time and tried running a bunch of things I haven’t started up this session. Memory never reaches 50% and CPU usage is negligible, but they all still take quite a while to start up.


#32

Oh wait. Isn’t that just htop?


#33

Yes, but running in yakuake and slightly modified by me.


#34

change compositer to xrender and animation speed to very fast


#35

I definitely don’t. Great idea.

Tried that already but applications still took a while to start up.


#36

Alright. I’ll give it a try.


#37

most credible is to use ssd


#38

Which apps are slow to start?


#39

I kid you not: everything. Even the widgets in the panel. But once they’ve been started up once, they open and restart just fine. For example, pacman is an anomaly really good for illustarting this: If I’d just turned my laptop on and opened pacman, it’d take 2-3 minutes just to show me the borders of the pacman window. But close it and reopen it afterwards, 1 second.

You mean pamac?

Try running from a terminal, does it report any errors? (command is pamac-manager).
