You probably need to check that your video card is using accelerated opengl drivers. If it's nVidia, ATI, or an S3 (Pro)Savage chip, you'll probably want to download the official drivers, and install them. 3D acceleration on X isn't that great for many cards, sadly. Have a look for DRI trunk drivers, if you're really stuck.

Hi Peter,

many thanks for that great looking screen
saver. But unfortunately I can't get it
run. I compiled it from source without
errors and installed it. When I try to run "kcometen3.kss"
a window appears and
the Desktop freezes.
I use a notebook with an ATI graphics
adapter. Other apps which use OpenGL
run without problems. Any hints what's
going wrong?

Second problem: I tried to make a RPM
with checkinstall but after a call to
checkinstall there are no binary files in the RPM.
Only dummy doc files are included.
I'll retry to make a RPM to make it more
convenient to install the screen saver.


Thanks in advance!
Bye
Marcus

Dude I really like this Screensaver. It looks so awsome. I would love to use it if I wasnt getting errors when install it from source. I get the same error the person above got. Do you think you can make a RPM version?

Hi,
I've installed the ubuntu package, but I still get this error when I try it :
kcometen3.kss: symbol lookup error: kcometen3.kss: undefined symbol: glPointParameterf

I think I just miss a lib, but which one ? :-(

Thanks very much !

Hi again,

I have found that it is just an opengl version problem (reading answers to other questions).
Now, I have an ati chip, it seems not to support opengl1.4 (only 1.3 ? OpenGL version string: 1.3.5395 says glxinfo )
I'll wait a few months again before being able to use it :_((

Hey, Screensaver compiled and worked great with c++ tools instaled, kde development tools installed, and the commands:

./configure --prefix=/usr -with-qt-includes=/usr/include/qt3

make

su

make install.

That's it... Thanks Man!

Have P4 running Gentoo w/ GeForce FX 5700 dualhead card, nvidia 7676 drivers. Have had past problems w/ this OS load, but is now pretty stable~

Dl'ed, and installed KCometen(great sreensaver!!!) Runs fine no apparent problems.

I will let it run when I leave work, come back next morning, and machine does not respond. Can not ping or ssh to. Nothing comes up on periph's. I know its KCometen, because if I change screensavers, it doesn't happen.

My only guess is CPU overheating. Gets caught in an infinite loop or something.

Any ideas on what I can look for to figure what is causing this??

How did you get this wonderful screensaver compiled under gentoo? I can't find a way...it don't find the Kde header (Kde 3.4.3).

Going to gentoo forums...

My bad. Not the screensaver. My system freezes regardless of the screensaver set. Acts like power management is kicking on, but pretty sure its not. Will start in the gentoo forums..... help welcome.

First of all: really great screensaver (as far as I can see from the screenshots ;o)).

But I'm not able to compile it under Suse10/kde3.5-Beta2 on an AMD64.

GL_POINT_SPRITE_ARB and GL_COORD_REPLACE_ARB must be defined in gl.h if the point sprite extension is available. it is possible that the extension is not available (glxinfo prints all extension which are supported) or that you need newer opengl dev files.

This is simply great!!! An excellent screensaver which should be standard in kde 3.5, if you ask me.. :-) *fingers-crossed*

That is what I get (KDE 3.4.3, gcc 3.3.6). Any ideas ?

you need the uic/moc program from qt to create the files from the kcometen3ui.ui file. if you have the programs installed then the files should be created when you type make.

I do have those qt programs. Snippet from configure output:

checking for perl... /usr/bin/perl
checking for Qt... libraries /usr/qt/3/lib, headers /usr/qt/3/include using -mt
checking for moc... /usr/qt/3/bin/moc
checking for uic... /usr/qt/3/bin/uic
checking whether uic supports -L ... yes
checking whether uic supports -nounload ... yes
checking if Qt needs -ljpeg... no
checking for rpath... yes
checking for KDE... libraries /usr/kde/3.4/lib, headers /usr/kde/3.4/include
checking if UIC has KDE plugins available... yes
checking for KDE paths... defaults
checking for dcopidl... /usr/kde/3.4/bin/dcopidl

This is gentoo btw, hence the paths. All my KDE programms got compiled from source and I have not experienced that error before.
Thanks for your patience.

First of all, i'd like to say that this is one of the most fascinating screensavers i've ever see(as the screenshot says) it compiled fine, but when i try to start it, the screen wents white and when i press the mouse button i come back to kde. tried with kde 3.5beta1 and an intel i855 graphics card. greatings pete

This happens when the screensaver doesnt find the pixmaps. Have you tried ./configure --prefix="/usr/" ?
I use the kde standard dirs for the pixmaps but kde doesnt find them when i do ./configure without --prefix="/usr/".

If i use KDEDIR=`kde-config --prefix` ./configure --prefix="/usr" && make to compile it. i see in the upper half of my screen the lower part of the screensaver and the lower half of my screen gets white. lg pete

That sounds strange. But the textures are now loaded correct ? Do you have the same problem with other screensavers ? (like KGLWater)

Report

OK, i'm sorry for blaming you. some screensavers work correctly some not. only gl screensavers tend to not work correctly.
