Re: Akonadi using 100% CPU resources

I noticed that akonadi services are using 100% of 16-core CPU resources
on my machine. I don't even use Kmail, I use Thunderbird. I'm not even
sure what akonadi is for. I have following packages installed:
$ dpkg -l | grep akonadi | awk {'print $2'}
akonadi-backend-mysql
…
libkf5pimcommonakonadi5abi1:amd64
System is Debian Testing.
How can I get rid of that akonadi, or disable it?
I don't have any Akonadi package on my system. Akonadi is like Evolution
Server on Gnome, a central database service for groupware functions.
I can't uninstall akonadi-server, because it wants to uninstall with
it:
akonadi-server* kaddressbook* kde-standard* kdepim-runtime* kmail*
knotes* korganizer* task-kde-desktop*
And dozens of libraries.
Some packages in your list are only meta or dependencies packages :
packages whom sole purpose is to simplify KDE installation with useful
dependencies (i.e. they install a bunch of packages). Have a look for
example at kde-standard. The others are all KDEPIM related packages.
Using Thunderbird you don't need any KDEPIM packages as Thunderbird and
its extensions can provide similar functionalities.
There is a quick and easy way to get rid of akonadi : build fake
package. But I prefer to open Aptitude or Synaptic and look at reverse
dependencies, this way I learn how to select KDE packages for my next
install.
For building fake package, just install equivs. There is plenty of
tutorials on how to use it. Then you can for example build and install a
new kde-standard package without KDEPIM dependencies (kmail, knote,
korganizer and so on). You will then easily remove KDEPIM packages and
Akonadi.
For reverse dependencies you will need to mark as "manual installed" all
task-kde-desktop and kde-standard dependency packages. So we start with
dependencies! Using Aptitude or Synaptic will help a lot. I recommend
Aptitude as it gives more informations.
- Opening task-kde-desktop, you will see that it depends on
kde-standard. Mark all other packages as manual installed (eventually
forgeting some of them that you don't need).
- Do the same with kde-standard
- Now you can remove these 2 meta packages. It shouldn't ask to remove
anything else.
- Then manually remove KDEPIM packages. Here you will probably need to
have a look at reverse dependencies to understand what will happened.
There is a very useful feature in Aptitude for thes task : in package
list mode, the bottom screen gives you short informations about every
packages. Pressing "i" keyboard key, you can switch between the 3 info
screen: first describe the package, second describe what will happened
with the action selected (update, remove, …), third show you why a
package is installed (reverse dependencies). All these info screen are
short, for more accurate informations you will need to open the
dependencies solutions proposed by aptitude (sometimes there is many)
and to open reverse dependencies in package screen.
Don't be afraid, all of this is easy.
Hope this help
