This script is now outdated as it does little to improve preformance in kde 3.0.2 and up. But I will leave it up for people with older versions of kde.


UPDATE: There are now 2 scripts. One is named 'startkde.faster' witch is basicaly
the same as version .05 but with some bug fixes. The other is 'startkde.fastest',
witch is MUCH faster, but does not include font overiding and may not work on
all systems the way you'd like it to. So try 'startkde.fastest' and if something
doesn't work switch to 'startkde.faster'. So just take the one you want and rename
it startkde, set the path in the first three lines of the script, and put it in your
path.

================================================================================

This is a drop in replacement for your startkde script. It disables ksplash
(It is so fast you don't need it!).

It works by basically pre-launching kdesktop, kicker, and kwin and launches kde
in the normal way. So you have a ready system wail the rest of kde loads. Then
when the kdeinit discovers that the window manager desktop and panel are already
running it just doesn't start another copy. (So you can start programs etc. and
you probably won't notice other stuff because it doesn't seam to be CPU or disk
intensive)

To use it just rename your existing startkde script and put this one in it's
place.

To clarify, the script is by default configured to work with kde3 located in
/opt/kde3. If you have kde2 or are not located in /opt/kde3 you should edit the
first 3 lines or it will not work properly.

=================================================================================

Quirks:

Ktip and the sound are still controlled by the normal startup so they may come
in later than you want. If you still want to have ktip, or a timely startup sound
then tell ktip not to start on login by unchecking it's box when it loads, and
uncomment the line about ktip in the script. (or with sound, just add artsd to
the list of pre-launch apps)

Next if you have the feature to have the cursor blink when you start an application,
that may happen after you login. (If this bothers you have to disable it.)

Finally it may be very slow logging off. If you experience this try using he
button on the panel or the one in the right click menu instead of the one in
the K menu. (This does not help under some versions of kde though)

If you have any other problems just e-mail me.

Seeing the last reply, I reckon this one is of no use for me. Fron login screen to a finished kicker now takes me about 6 to 8 seconds...

For slower computers, this wouldn't be a bad tradeoff. But even on my 250MHz machine, the tradeoff was horrible. What do I mean by tradeoff? Well, you can access the Kicker faster, but some system services that programs rely on don't load until about 10-20 seconds after the kicker. So, you're limited in functionality during the additional uptime. Secondly, the new script over doubled my logoff time. Here are my clock results:
startkde.fastest:
Time from login to kicker: 26.04s
Time from logoff to login screen: 30.18s
System Services: Apprx 10-20s
startkde[without fonts]
Time from login to kicker: 49.45s
Time from logout to login screen: 12.34s
System Services: Already done
In my not so expert opinion, the only people who should use this are the people running KDE on OLD machines. Otherwise, just takeout the fonts, and make other optimizations. However, it was a good idea - nice try. Maybe additional work could iron out these problems ;-)

See for example http://lists.kde.org/?l=kde-core-devel&m=102171438903866&w=2
The patch is wrong, because it breaks the proper startup order, and your KDE may therefore not work correctly. There are also people for whom it actually doesn't cause any startup time decrease.
In case somebody will carefully compare this modified startkde script and the original one and will find out what's causing the big difference for some people, please report it.

Hi all,

now that i had a closer look to the scripts is clear that i am an idiot. SuSE8 defaults to ".kde", these scripts to ".kde3" so it was clear that my configuration was ignored when using theses scripts instead of SuSE`s.

Having changed the definitions in your script-header from ".kde3" to ".kde" works everything very fine.

Thank you for your work!

Bye

Using something similar to this, would it be possible to implement a "switch user" thingy where kwin etc. is left running in the background, with another kdm in the foreground so that other users can login. I assume this would require a change to kdm (so you can log back in) - would it be difficult?
I know I can have multiple X sessions, but it's just not the same :-)

Switch user (a.k.a fast user switching) has been implemented in kde 3.4 beta1.

KDE does seems faster at startup. I was very annoyed by watching splash screen everytime KDE starts, which I felt slows down.

Thank you, I appreciate it.

I 'm feeling a little dumb at the moment, but where is the startkde3 script?_? i've found just a startkde script it's the same?_?

it should be in /opt/kde3/bin/ (at least it is for me) and no, that is differnt from startkde.

If you don't have kde3 you may want to wait a few days for a kde 2.2 version. Or you could try inserting those 3 "Preload" lines into your startkde script and see what happens.

Great, exactly how I like it. Now, if only the rest of my Linux worked in the same way, i.e. X and KDE boots up as soon as possible and services like cups and smb after that in the background.

You can change the order of started services.

If you'll look into /etc/rc3.d (or whatever directory your distro using and your default run level) you see something like SXXcups SXXsamba.

XX determines the order of services started (lower means started first). Arrange them to your liking.

So what are the drawbacks? It sure is faster, but what does it not do?

Well, other than the Logout from the K-menu, the ktip, and the overriding fonts I mentioned, not anything.

Because it loads the Desktop/panel/window manager first, then does the usual kde stuff.

So then when the kdeinit discovers that the window manager desktop and panel are already running it just doesn't start another copy.

So after about 20 sec (usual kde load time) it is exactly the same as it would be with the default script.

All the problems I mentioned are either come directly from these thins not being session managed in the usual way. (So I don't think there will be any other problems)

About the fonts though, If you want to use font overriding, just copy that section from your existing startkde3 script. (I just removed it because it took time and it is not something most people need)

If you have any other problems just e-mail me.
