Mageia forum

I installed Mageia 3 beta 4 x86_64 live KDE DVD via USB stick on an external USB disk.
I copied my MP3 music to the /home partition on this disk.
I start Amarok and it plays fine.
Then I start some kernel compilation activities via su in a shell.
When exiting from su, Amarok stops playing and the "progress bar" freezes.
Doing su again makes Amarok continue playing.
Amarok only plays when there is a root shell.

Who understands what is happening here?

I have been seeing some similar weirdnesses. When I am doing admistrative tasks on LXDE as root, when package update runs as part of the Mageia Online applet, I get root password fail dialogs popping up on the screen. Why are processes of one parent sending their output to a different parent process? Not the same as what you are seeing of course, but very similar. In your case one child process (Amarok) is being affected by a different child process (su). This is VERY weird and something I have never seen before with Linux. And, by the way, I am not seeing this on my 32bit system, ONLY on my 64bit system, AND it only started to happen recently after a package update. - George

I created
Bug 9799 - Sound system blocked by exiting root terminal (M3 beta 4)
https://bugs.mageia.org/show_bug.cgi?id=9799

I tried to unconfigure autologin via KDE System Settings / System Administration / Login Screen / Convenience / unclick Enable Auto-Login. Root password was requested but autologin was still automatic.

Then I put /etc/sysconfig/autologin to "no" and now I have to login, so autologin is successfully disabled.

AND... issue is SOLVED... root exit no longer disables sound...
