sizeof(bb_config.c_display) is not correct, it gives the size of a pointer. Also strcat should not be used due to the risk of a buffer overrun.
What about:
char unix_x_display[16]; snprintf(unix_x_display, sizeof(unix_x_display), "unix/%s", bb_config.x_display);Alternatively, you could set g_strdup_printf("unix/%s", bb_config.x_display), but that needs to be freed afterwards.

Thanks for catching that; I don't do much C.
Fixed as requested.

XOpenDisplaytries all protocolls in turn (socket, IPv4, IPv6) [1]. This can lead to delays and timeouts, especially on systems with incomplete/etc/hosts(eg. missinglocalhost→127.0.0.1), due to the fact that the hostname has to be resolved.Since we start the X server not accepting TCP connections, we can pass the protocoll to
XOpenDisplay.Closes #782.
