Comment 8 for bug 1758243

@Roman: I don't know what might be wrong. You might be able to get more information with the command "systemctl status bumblebeed.service". Also, you could try "tail -f /var/log/syslog" in one terminal before running "optirun glxinfo" in another and check back on the tail output afterwards. "journalctl -e" might also have some relevant info.
