Description:
Rootless X crashes when I open firefox. The first error in the log is

[ 7.448] (II) xfree86: Adding drm device (/dev/dri/card1)
[ 7.948] (EE) systemd-logind: failed to take device /dev/dri/card1: Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken.
[ 7.948] (II) xfree86: Adding drm device (/dev/dri/card0)
<snip>
[ 8.796] (II) xfree86: Adding drm device (/dev/dri/card1)
[ 8.797] (EE) systemd-logind: failed to take device /dev/dri/card1: Device already taken
[ 8.797] (EE) /dev/dri/card1: failed to set DRM interface version 1.4: Permission denied

card1 is the discrete card (ATI 6630M). card0 is intel, which is what's being used. This is an erratic crash, usually I can just restart X and things work fine.

Additional info:
* Xwrapper.config:
allowed_users = anybody
needs_root_rights = no
* xorg.conf.d/20-intel.conf
Section "Device"
Identifier "Intel Graphics"
Driver "intel"
Option "TearFree" "true"
EndSection

Steps to reproduce:
1. login
2. startx
3. $ firefox
   Xorg.0.log.old (23.2 KiB)
This task depends upon

This might be a workaround: rebuild the xorg-server package without systemd-logind support. Get PKGBUILD from Arch package repo [1], edit the ./configure command in PKGBUILD file to say '--disable-systemd-logind' instead of '--enable-systemd-logind', and 'makepkg -si' as usual.

Looks more like a timing issue which was fixed with latest version of dbus. Is thuis still an issue?

Unfortunately still an issue. I'll try the workaround
   Xorg.0.log.old (23.5 KiB)
