Control: tags -1 + moreinfo Hi Sayat,
sorry for the very late answer. That dialog comes from cinnamon-launcher: it shows up when the cinnamon process crashes, and meanwhile metacity is started as a fallback window manager. So during that boot Cinnamon crashed every time it was restarted, and on the next boot it worked again.
Without logs from that boot it's not possible to tell what crashed. Has it happened again since then? If it does, right after the next reboot please send:
- the file ~/.xsession-errors.old (at each login LightDM moves the log of the previous session there, so it's lost if you log in more than once in between)
- the output of: journalctl -b -1 | grep -i -e cinnamon -e segfault Best regards, Fabio
