I don't know about 19:32:32 but it sounds like Xorg might have crashed around 19:44:04 and 20:25:10.
So please repeat the steps in comment #2. Also if you can find your Xorg.log file from when a crash/freeze happened then please attach that. -- 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/1880991 Title: [nvidia] Xorg freeze To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/1880991/+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
