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.

when trying to change to this wallpaper in kde 4.6b1, plasma crash will occure

backtrace: http://pastebin.com/f9xRz4VQ

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.

ups...this is definitely on my side. i was sure i've wiped out all kde related stuff before upgrade to 4.6b but i apparently did not and this pkg was really old. rebuild help, sry for wasting your time

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.

During the installation, here the error message with the compilation :

What can I do to solve this error please?

I use KDE 4.3 on Debian sid

Thanks!!

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?

I should installing a specific package??

yes you need kdebase-workspace-dev. It should work after that :)

Yes, effectively it work better with this package ! !

I'm going to learn to read a README file ;-)

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 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 :)

In my PC Athlon64 3800, nvidia 6200, 1GB RAM can not be used, the whole system slow.
In Laptop Core 2 Duo 2.4GHz, NVIDIA 8600M, 4GB RAM, runs stable, but considerably consume resources.

Yes this wallpaper is very resource consuming :). I recommend leaving it in paused mode most of the time.

In the next version I'm thinking of adding the ability to pause the wallpaper automatically when there are windows open or a window is maximised.

The reason why it uses so much resources is because it uses software rendering. Using hardware accelerated drawing like openGL would considerably reduce resource usage.

So far I have not been able to successfully use direct openGL rendering. If anyone out there can help me it will be very much appreciated :D.
