Today this happened again (I don't know why). ~/.xsession-errors told me (with a timestamp some hours ago, when the system still worked properly):
openConnection: connect: Datei oder Verzeichnis nicht gefunden cannot connect to brltty at :0 However, after I shut down the whole system and rebooted, it told exactly the same, but the file had a timestamp close to the reboot. dmesg showed, that I connected and disconnected the LAN cable seveal times (ok, I did it) and that I connected an usb device and then it showed that the computer connected to WLAN (wlp3s0: associated). free -m shows me: gesamt benutzt frei gemns.
