OK this looks like a proper freeze, meaning nothing has crashed and nothing is logging about it. To move forward, please install 'openssh- server' so you are able to log into the machine from another machine and observe the freeze.
Please log in to the affected machine via ssh and during the freeze run: ps auxw > processes.txt and send us the resulting text file. While you are there please also run 'top' and check to see if any processes are using high CPU. -- 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
