Tested on multiple computers. With Kubuntu and BigLinux distributions.

Replace in /usr/bin/startkde:

Code: Select all

LD_BIND_NOW=true /usr/lib/kde4/libexec/start_kdeinit_wrapper +kcminit_startup

By:

Code: Select all

if [ "`grep Hidden=false ~/.config/autostart/plasma-netbook.desktop`" = "" ]; then
    LD_BIND_NOW=true /usr/lib/kde4/libexec/start_kdeinit_wrapper +kcminit_startup +kwrapper4 plasma-desktop
else
    LD_BIND_NOW=true /usr/lib/kde4/libexec/start_kdeinit_wrapper +kcminit_startup +kwrapper4 plasma-netbook
fi

In my tests the average gain was 5 seconds to load KDE.

Thanks for the tip....
Maybe I'll try this on my testing pc

Interesting.

Just wanted to note that ~/.config is a directory value which can be reconfigured using a certain environment variable: $XDG_CONFIG_HOME

I it is set (and not empty) it points to the local config directory.
$HOME/.config is used as the default if it is unset or set to empty.

Didn't work for me (no time to inspect why though), but prebinding could be really beneficial to the startup process.

I tested only on distributions Kubuntu, and BigLinux.

The most notable difference is only with the active ureadahead. I do not know how this change behaves in other distributions.

Well don't see any change in LinuxMint 9 Kde Edition (4.4.5)

I have the package ureadahead

Appears to make some improvement here, on archlinux, but I have not tried to measure it.

Great tip!
I can confirm a reduction in loading time of around 5 seconds.

I'm running KDE 4.8 on a LFS system.

Hi all,

I made this change as well on a Gentoo system.

I am not sure at what part I should get the time reduction.

In the past I had after logging in and after the little animation that a few seconds my desktop was not responding(at least the kde part) ( after a few seconds it was responding).
That seems to be solved now however I want to evaluate this further as my issue might not be happening all the time.

So I keep you guys posted.

This tip breaks the taskbar thumbnails effect.

Sorry guys, I can't confirm if this acutally speeds up or not.
It seems that the problem I described earlier isn't occuring that often anymore however that might have to do with other things.

Same, for me.

For me with KDE 4.10.5 this works fine without issues. I just skip the IF/ELSE condition and replace my LD_BIND_NOW with the desktop string (the first one), because I use desktop PC. If you use netbook use the netbook string (the second one).

Thanks for the nice tuning My KDE load time now is around 5sec
