Howto: Install and use projectM music visualizer with pulseaudio support on Hardy

[fedevit]

I get this working by running projectM-test but, as said Mr.Roger, it has no menu.
Any help?

[krul]

Followed tutorial, and it is working great!!

Any idea how to get this to work as wall paper or screensaver?

Followed the tutorial step-by-step. Didn't work; it fell at the last hurdle - it says:

cMake Error: Error in make code at
/home/peter/projectm/projectM-Trunk/src/libporjectM/cMakeLists.txt:5:
Unknown CMake command "cmake_policy".

Any ideas as to what wet wrong please? Cheers.

Fixed this by upgrading from 8.04 to 9.04.

I have then run into the "segmentation fault" problem described here:
http://ubuntuforums.org/showthread.php?t=1125440

the fix at the very end

I tried to change the options in the ccmake configuration to get projectM work.
When I switched the use of frame-buffer objects off (set USE_FBO to "off") it finally worked..

worked for me there.

I then ran into the blackscreen problem here: http://sourceforge.net/tracker/?func...01&atid=637260
Using the workaround described there worked.


I'm using Ubuntu 9.04 on a Nvidia Geforce mx440, german (non-english).
Since all this took me a while I'll post this here.. hope it helps someone

Thanks for the tip. After changing the local it realy works. Now the wired behaviour also makes sense, if dots are changed with commas...

Only problem I have now is, how can I set LC_NUMERIC=C in the .desktop file? So that I can start it without the terminal.

[fedevit]

Thanks a lot!

It works for me too. The only thing I needed to do was to launch the program by typing:

LC_NUMERIC=C projectM-pulseaudio


instead of

projectM-pulseaudio



cheers

[Mr. Rogers]

To fix the localization problem (switching , and . when reading presetfile) do the following:

Open file projectM/src/projectM-pulseaudio/qprojectM-pulseaudio.cpp. And go to line 91:

After the line "QApplication app ( argc, argv );" you should add a new line with "setlocale(LC_NUMERIC, "C"); // Fix".

The code should now look like that:

int main ( int argc, char*argv[] )
{
    int i;
    char projectM_data[1024];

    QApplication app ( argc, argv );
    
    setlocale(LC_NUMERIC, "C"); // Fix

    std::string config_file;
    config_file = read_config();

    
    QMutex audioMutex;

Now you can recompile and start the application normaly.

Anyone know how i would start projectM in fullscreen mode?

changing the "fullscreen =" line to true (in the config.inp) doesnt work.

Nevermind.. I didnt think of the possibility that there is a checkmark in the gui for this. Way too easy

[fedevit]

Anyone know how i would start projectM in fullscreen mode?

open ProjectM

type

m

then click "settings"
and tick "Fullscreen on startup"

restart projectM and you're done!

You mean in order to get it to work on Hardy.... I have to use Intrepid?

I don't know, I'm sure there's another way.. but that's what worked for me.
