kubuntu Faster ? tricks

Use kubuntu packages

you can even try to use a repository package that will help you to speed up kubuntu just do this

sudo apt-get install kubuntu-low-fat-settings

some of these tricks are on the package 🙂


Improve performace (if you need it):

    • swappiness  ; you can set your swappines with this(ONLY NEW COMPUTER with a lots of ram):
      kdesudo kate  /etc/sysctl.conf

      add , if you have not , this string :

      vm.swappiness = 10

    • you can even  set your computer to load , at the boot time ,  some process in a parallel way with this
 kdesudo kate/etc/init.d/rc

search for this :


and set it like this


Set the desktop to use less ram disabling some stuff ….

there are gif animated photos =====> click on the picture to see

Well you could just do everything even if you have a nice ultrafast machine but.. i guess it’s not usefull to remove features and candy if you have that machine.

Anyway under some conditions you could want to decrease the ram usage, that could mean more battery for example.

Disable Semantic Desktop search

The most of time you would like disable only akonadi and nepomuck and stringi for that you need only to do this

Disabling Kwin effects

Disable the Oxygen Animations

Kde is very candy and beautiful with all these animations on menus but.. it could be too much heavy , i think to the netbook for example. So how to disable them ?

Disable Akonadi

kate ~/.config/akonadi/akonadiserverrc

set startserver=false

kate ~/.config/akonadi/agentsrc

after that this


replace akonadi with  #akonadi ; thsi will disable the istances you want disable .

Configure qt engine

sudo apt-get install kde-config-qt-graphicssystem && kbuildsycoca4

then go on system settings and set raster (FOR SOME VIDEO CARD PLASMA COULD CRASH reset to XRENDER IF IT HAPPENS )

Now faster krita && koffice

follow the white rabbit  xD

kate  “$HOME/.OpenGTLDebugConfig”

put thsi into

GTLCore = false
OpenCTL = false
OpenShiva = false

NOW KDE IS SO HEAVY? of course not ^^

    what is akonadi?
    I use Ubuntu since it’s born, going around between RedHat and Ubuntu and have been with gnome since 9 years a ago. Now, I try Kubuntu 10.04 just to feel KDE. Yeah, there are huge gap between ubuntu and kubuntu since kubuntu developed only by community. I guess, i try to stick around with Kubuntu at least for a week. -_-

  2. betweenmeandlinux says:

    Do u still use Kubuntu(KDE)? or move to Ubuntu (gnome).
    I give up with Kubuntu 10.04,
    1. it took most of my RAM (900 MB)!
    2. it recognize partition on my harddisk as /media/disk or /media/disk-1 depends which one i mount first
    3. using kate is complicated
    4. for unknown reason, command ln -s is failed to create symbolic link – after that I use dolphin to create link
    5. my wine report missing DLL, which already exists in same folder with application
    6. KDE notification is really annoying

    Instead of Kubuntu, I switch again to Ubuntu 10.04.

    I want to try KDE, but from scratch. Have any suggestion how to do it? Maybe all Ubuntu functionality but KDE look?

      i guess you have not to try kde.

      kde it’s a complete destkop and not an old destkop like gnome2. It has semantic destkop!

      btw have you seen the screen , to me it run right now with 250mb of ram used.

      1 900 mb without programs it’s not normal. at startup i guess i have 180mb with kwin effects.
      go on system monitor and see what it sais , there should be an application that sucks . kill it.

      2 my partition is always mounted like 2 years ago and i have the same names.
      3 kate complicated ? you used gedit before it’s perfectly normal to feel something complicated because you have ever used it
      4 here it works
      5 do you use wine? wtf :S never used sorry i don’t need it
      6 there are colibri notification and btw you can configure kde notification systemsetting notifications … bah… or right button on notification icons …

      i guess kde it’s not for you. i will suggest lxde 🙂 or gnome2 at least untill is removed from ubuntu repo.

      right now i am using kubunut 11.04 without issue

        I re-install KDE again but this time on ubuntu-server 10.04 after that I install kde-plasma-desktop.

        2. nautilus can mount device with its label or by UUID when the device has no label. I stuck with dolphin, it always mount device to /media/disk. I’ve tested it with nautilus and dolphin on same system. I need to configure dolphin to mount by UUID without editing /etc/fstab.
