Star Field Plasma Wallpaper

Star Field Plasma Wallpaper
zoom


Minimum required   KDE 4.x
Downloads:  2228
Submitted:  May 31 2009
Updated:  Jan 20 2013

Description:

This plasma wallpaper draws an animated starfield in the background of your
desktop. It was inspired by the star field chrome experiment -
www.chromeexperiments.com/detail/starfield/

INSTALLATION
------------
Firstly make sure you have the KDE workspace development files installed. For ubuntu run: sudo apt-get install kdebase-workspace-dev

If the source came in a zip then unzip it first. To install run install.sh:
Open up a terminal, navigate to the the starfield directory which has
install.sh then type:

./install.sh

You may be asked for your root password during installation.

After installing log out and then log back in. Then right click on your
desktop, go to 'Desktop Settings'. Then in wallpaper type you should see
'Star Field'.

CONTROLS
--------
- Dragging the starfield with the left mouse button will change it position
- Middle clicking on the wallpaper will pause the animation
- Mouse wheel scrolling will change the perspective of the view.

CPU USAGE
---------
This wallpaper can be quite CPU intensive. To reduce the CPU usage you may try
the following:
- Pause the wallpaper. This should make the wallpaper use 0% CPU
- Enable 'Pause when desktop loses focus' in the advanced options
- Reduce the frames per second. This is THE main factor in deciding the CPU
usage. 15 FPS gives a somewhat smooth animation.
- Reduce number of stars
- Use a blank background (Leave the background path empty)
- Reduce trail length
- Use a lower quality
- Turn off antialiasing
- Use plasma in raster mode. To do this first quit plasma then restart it with
-graphicssystem raster argument:
For KDE 4.2:
kquitapp plasma
plasma -graphicssystem raster

For KDE 4.3:
kquitapp plasma-desktop
plasma -graphicssystem raster

However be warned that this method has not been thoroughly tested.

NOTE: Star speed does not affect CPU usage.


ENJOY!!
-------

 Plugin kills plasma?

 
 by Phobeus on: Jul 15 2009
 
Score 50%

Hi,

I am running this plugin using a self-compiled version under Gentoo. After about 3-5 Minuten, suddenly the whole plasma desktop ist getting crazy and several parts seems not to be redrawn. The log is showing repeatly:

QPainter::setCompositionMode: Painter not active
QPainter::end: Painter not active, aborted
QPainter::begin: Paint device returned engine == 0, type: 3

If the plugin is deactivated, everything seems to run stable. Any ideas?

Thanks for the bug report :)

Unfortunately I have not been able to replicate it on my machine. I tried on both 4.2 and 4.3 trunk running on Kubuntu.

What KDE version are you using? Are you using any non-standard plasmoids?

BTW how do you look at the log files? I've been trying to find them but couldn't...

It's a KDE 4.2.95 from Gentoo KDE Testing. I really could use a timer to reproduce it. Looks also like it is not a problem with the theme... they colors might vary, but I can reproduce it with "tragedy" and "luft". I am using only a systemmonitor for hardware and bubblemon as additional non standard plasmoids.

For the logs... just kill plasma "kquitapp plasma-desktop" and call "plasma-desktop" from a konsole. You can see its message then.

Hmm... Unfortunately it's hard to tell why this is happening. It could be due to the large number of repaints on the screen screwing up plasma. Or it could be due to some other unrelated bugs.

If you could upgrade to KDE 4.3 when it is out and report back again that would be great :)

 Pause mode

Congratulations on the amazing work. Is it possible to add a feature such that the starfield will pause automatically when there is a window open that has been maximized and has complete focus for a certain period of time?

Thanks :)

I think it is possible to detect when a window is maximised etc. This is one of my plans for the next version.

Another plan is to have a 'skybox' mode where dragging the desktop would rotate the background and the starfield and would let you look around. However this seems a bit complicated and would probably be slow...

Hi

I think this might be a problem with my CMakeLists.txt file. I have now copied the CMakeLists.txt that Smooth-tasks uses since it also uses taskmanager.h. Can you try recompiling and see if it works? If it doesn't then could you try to see if Smooth-tasks compiles on your machine?

Hi. Sorry for my late reply.

I tried running the wallpaper on KDE trunk and it worked fine. I am using:
- kdelibs and kdebase trunk (updated yesterday)
- Qt 4.7
- X Server 1.9

Have you tried recompiling the wallpaper? That might be the problem. What version of the libraries above are you using?

Thanks for reporting the problem :)

it's actually from pkgs from arch kde snapshot repo https://bbs.archlinux.org/viewtopic.php?id=76245&p=30

and AFAIK it's compiled from this sources http://websvn.kde.org/tags/KDE/4.5.80/

i'm using (almost) stable arch, so qt4.7 and xorg 1.9

I'm also using arch but compiling kde from svn myself. Since the wallpaper worked for me, I suggest that you try re-installing it from AUR again. That should make it recompile and it should hopefully work.

Don't worry. Thats fine. :)

But since there was no need to recompile from 4.4 to 4.5 maybe there is something wrong with the code since it needs a recompile for 4.6.

Nice!

One thing: CMakeCache.txt needs to be removed from the current package - as it references the authors particular source directory and will break compilation.

Also, it would be nice if there were an advanced option to disable handling of the mousewheel... so that it can still be used for rotating to other desktops with the cube.

Do you like or dislike Ubuntu Unity?
 Yes, unity is alien technology!
 It is less confusing than Gnome 3 default, shell.
 Granny thinks it is much more usable than Gnome 2
 Canonical is embarrasing itself with this split project
 Gnome 3 default shell is much better
 I dislike Unity, Gnome 3 default shell is alien technology!
 None of the above, I like the 2Gb for free and Apple alike behavior. Will post a comment instead
