Comment 3 for bug 1395547

- xfce4-volumed seems not to be working properly after that
- Restarting xfce4-volumed fixes the multimedia keys not working. One CPU core is still used by xfsettingsd
- Restarting both xfsettingsd and xfce4-volumed or just xfce4-volumed fixes the CPU issue
- If I kill xfsettingsd, leave xfce4-volumed running, run xflock4, unlock the screen, xfce4-volumed seems to be working fine and CPU issue does not manifest
- If I kill xfce4-volumed, leave xfsettingsd running, run xflock4, unlock the screen, I run into the CPU issue. Restarting xfsettingsd resolves the issue

This leads me to believe it's not a xfce4-volumed issue. It looks like these two are influencing each other, though, or something along those lines. Maybe xfsettingsd and xflock4 influencing each other?

One more thing - when unlocking with xfsettingsd running, the whole system seems to freeze for about 10 seconds or so, even the CPU monitors or time displayed in the corner are not moving during that period.
