Hi, It's a regression in the pam module for systemd: https://bugzilla.redhat.com/show_bug.cgi?id=753882
It affects all distributions afaik and it can make any app/package using XDG_RUNTIME_DIR crash if it's used with root privileges (including dconf)... This is a huge bug. I think the most relevant person to look into this on your side is Martin Pitt. Let us know if we can help on our side. As always we're available at #linuxmint-dev on irc.spotchat.org. Here's a quick way to troubleshoot it: echo $XDG_RUNTIME_DIR sudo su - echo $XDG_RUNTIME_DIR In raring, this returns different paths. In saucy they collide. This is because /etc/pam.d/common-session* no longer use Ubuntu's libpam-xdg-support (xdg_support.so) but the systemd pam module. As far as I understand it from the https://bugzilla.redhat.com/show_bug.cgi?id=753882, this isn't actually a bug in systemd, but a change by design. We're considering solutions in Mint and we'd love to talk to you about it. We've a few ideas we can run by you and it would be better for everyone if we tackled this the same way in Saucy/Petra and got involved in the upstream discussion. ** Bug watch added: Red Hat Bugzilla #753882 https://bugzilla.redhat.com/show_bug.cgi?id=753882 -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to pulseaudio in Ubuntu. https://bugs.launchpad.net/bugs/1197395 Title: /run/user/$ID/pulse owned by root and not by the user Status in “pulseaudio” package in Ubuntu: Triaged Bug description: I'm experiencing this problem with Ubuntu Saucy. Some times, when I start a media player (I use Musique), it freezes, as it finds that it cannot write into /run/user/$ID/pulse. If I change the owner of that directory to me, the media player starts as usual and is able to play music. I've never had this problem with previous versions of Ubuntu. Someone says that running PulseAudio with the -D argument changes the owner of that directory, but I didn't try. This is before manually changing the owner of that directory: $ musique Failed to create secure directory (/run/user/1000/pulse): Permission denied+ ... # it doesn't crash, it keeps waiting If needed: (dmesg attached) lspci: 00:00.0 Host bridge: Intel Corporation Mobile 4 Series Chipset Memory Controller Hub (rev 07) 00:02.0 VGA compatible controller: Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller (rev 07) 00:02.1 Display controller: Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller (rev 07) 00:1a.0 USB controller: Intel Corporation 82801I (ICH9 Family) USB UHCI Controller #4 (rev 03) 00:1a.1 USB controller: Intel Corporation 82801I (ICH9 Family) USB UHCI Controller #5 (rev 03) 00:1a.2 USB controller: Intel Corporation 82801I (ICH9 Family) USB UHCI Controller #6 (rev 03) 00:1a.7 USB controller: Intel Corporation 82801I (ICH9 Family) USB2 EHCI Controller #2 (rev 03) 00:1b.0 Audio device: Intel Corporation 82801I (ICH9 Family) HD Audio Controller (rev 03) 00:1c.0 PCI bridge: Intel Corporation 82801I (ICH9 Family) PCI Express Port 1 (rev 03) 00:1c.1 PCI bridge: Intel Corporation 82801I (ICH9 Family) PCI Express Port 2 (rev 03) 00:1c.2 PCI bridge: Intel Corporation 82801I (ICH9 Family) PCI Express Port 3 (rev 03) 00:1c.4 PCI bridge: Intel Corporation 82801I (ICH9 Family) PCI Express Port 5 (rev 03) 00:1c.5 PCI bridge: Intel Corporation 82801I (ICH9 Family) PCI Express Port 6 (rev 03) 00:1d.0 USB controller: Intel Corporation 82801I (ICH9 Family) USB UHCI Controller #1 (rev 03) 00:1d.1 USB controller: Intel Corporation 82801I (ICH9 Family) USB UHCI Controller #2 (rev 03) 00:1d.2 USB controller: Intel Corporation 82801I (ICH9 Family) USB UHCI Controller #3 (rev 03) 00:1d.7 USB controller: Intel Corporation 82801I (ICH9 Family) USB2 EHCI Controller #1 (rev 03) 00:1e.0 PCI bridge: Intel Corporation 82801 Mobile PCI Bridge (rev 93) 00:1f.0 ISA bridge: Intel Corporation ICH9M LPC Interface Controller (rev 03) 00:1f.2 SATA controller: Intel Corporation 82801IBM/IEM (ICH9M/ICH9M-E) 4 port SATA Controller [AHCI mode] (rev 03) 02:00.0 Network controller: Qualcomm Atheros AR9285 Wireless Network Adapter (PCI-Express) (rev 01) 85:00.0 Ethernet controller: Marvell Technology Group Ltd. 88E8072 PCI-E Gigabit Ethernet Controller (rev 10) From /var/log/syslog: Jul 3 14:44:12 Davideddu-Laptop pulseaudio[11387]: [pulseaudio] core-util.c: Failed to create secure directory (/run/user/1000/pulse): Permission denied Jul 3 14:44:12 Davideddu-Laptop pulseaudio[11387]: [pulseaudio] main.c: User-configured server at {781995e0a8db2617790d55ca51c37499}unix:/run/user/1000/pulse/native, refusing to start/autospawn.
