Thanks. That's an interesting log because it ends one second after booting (!), but shows no evidence of a freeze.
I suggest what to do next is to wait until a freeze happens while you're using it. Then reboot and again run: journalctl -b-1 > prevboot.txt ** Tags added: hybrid nvidia -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg-server in Ubuntu. https://bugs.launchpad.net/bugs/1876489 Title: Xorg freeze To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/1876489/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
