Dan Watkins, thank you for reporting this and helping make Ubuntu better. 1) Is this something that started to happen after an update? If so, which specifically?
2) After the freeze, are there crash files in /var/crash? 3) As per your logs, you are using kernel 4.13.x (not supported in Ubuntu 18.04). Hence, if you restore your kernel to a supported version (4.15.x) is this still reproducible? ** Changed in: xorg (Ubuntu) Importance: Undecided => Low ** Changed in: xorg (Ubuntu) Status: New => Incomplete -- 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/1751120 Title: Xorg freeze when moving a window between external/internal monitors To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1751120/+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
