               Build:  
[06:26:39.134] OS: Linux, 3.8.4-1-overclock, #1 SMP PREEMPT Sun Mar 24 23:45:50
EDT 2013, x86_64
[06:26:39.134] Loading module '/usr/lib/weston/drm-backend.so'
[06:26:39.135] initializing drm backend
[06:26:39.138] couldn't open /dev/dri/card0, skipping
[06:26:39.138] failed to initialize egl
[06:26:39.138] failed to drop master: Permission denied
[06:26:39.146] fatal: failed to create compositor

This is caused by trying to use a tty that the user does not have permissions
for, instead of the current tty for which systemd-logind gives permissions.

Running "weston-launch -t /dev/tty1" on tty1 will run correctly.

This only occurs when the user does not belong to the video or weston-launch
groups, so that pam via systemd-logind is exclusively relied on to give
permissions.
