dmesg -w In the other run: journalctl -f Now wait and reproduce the freeze a few times. Each time look at those two Terminal windows and tell us if you see any particular messages just after each freeze. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1851349 Title: GUI freeze To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/1851349/+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
