Interesting. That does start to confirm my suspicion that the problem lies outside the screensaver.

Thanks for pointing out the bug report. I'll keep an eye on it.

Could you provide a second screensaver just with the lightning?
I'm sitting in front of my screensaver just looking for the lightnings ;)
Same setup, just without the comments and a setting for adjusting the frequency of the lightnings.

Great work :)

That seems like an interesting idea. I'll check if we can do this just by changing some options.

This was the solution posted for the screensaver not showing up in System Settings:

Sounds like it's not indexing kcometen4.desktop

Add this to the bottom of your ~/.profile

Quote:
export KDEDIRS=/usr/local:/usr

Unfortunately I am extremely newb to Kubuntu and I have no idea where that file(?) is. I appreciate your patience, I do enjoy the preview and would like to make Kcomet my default saver.

Thanks,

Hi. Kcometen4 is already in kubuntu (in universe)

Just remove whatever kcometen4 stuff you installed under /usr/local. Then 'sudo apt-get install kcometen4'. That should do it.

Thanks. But to give credit where it's due, I just fixed a few bugs and ported to KDE4. The beautiful stuff comes from the author of KCometen3, but he seems to have disappeared.

Hi
I like this screensaver and I modified it though it works with OpenSuSE 11.2 x86_64 and KDE 4.3.5. The RPM Package can be downloaded from www.linux-specialist.com/download/rpms/suse11.2/loopy-0.5.3-1.x86_64.rpm
If someone want's to have the Spec File to buld a package for another distro - just let me know an I will publish it as well.
Have a nice day.

Then restart your session. Does it show up in system settings now?

There's a rpm that works like a charm in Mandriva 2010 too.

Hi there,

Compliments to the author of this great screensaver

I wonder if someone can help me, if I use kwin as my window manager the screensaver shows my desktop in the cube fine, but if I use compiz all I see is the comets in a black background, it doesn't grab a desktop shot.

well actually it does, but only maybe 1 in 10 times, most of the time it doesn't, and the background is just black, its quite strange.

Is there a fix/workaround for this little issue??

Someone else had a similar problem back in May, but I haven't been able to reproduce it.

Try this. Edit kglcometen4.cpp:135 so it looks like this:

qglClearColor(QColor(Qt::transparent));

and recompile. Does anything change?

Hi there,

Thanks for the reply, sorry I took so long, but that doesn't fix it

I'm using Fedora and this screensaver is in the rpm repo's, I originally had yum installed it, but I thought first I'd try to build it from source, and still the same thing happens.

Then I did make uninstall and re unzgip'ed the package into a new folder and made the changes you suggested to kglcometen4.cpp and rebuilt, but it still doesn't fix it :(

sorry

Oh I should also mention that its fine in the preview aswell, I get a desktop grab in the preview, its only when I wait for X amount of minutes and it kicks in automatically that I dont get a desktop grab and it displays comets on a black background, I suspect there is a box in there its just black because the camera still pans about

Yeah. I wasn't very optimistic that the change would help, but it was worth a shot. I doubt that this is even an issue in KCometen4 itself. Would you mind PM'ing me with info on various versions that you're using? (specifically compiz, kde, qt) I'll take a closer look when I get a chance.

Installed Kubuntu 9.10.
"./configure" fails with message:

Any clue ?
Thanks a lot in advance

It looks like you don't have all the devel packages installed. Try:

apt-get install kdebase-workspace-dev libqt4-opengl-dev

I think binary packages are also available in Ubuntu universe.
