1. If there's a relevant message in the kernel log then if will be obvious -- filling it up. Though if you have a full syslog already then that might contain the answer, so yes please attach it.
2. I guess log in via ssh and stay logged in before the problem starts. 4. We still need to test Wayland as a confirmation that the problem is confined to Xorg. It's not a matter of Ubuntu not recommending Wayland, it's to help us triage and understand this bug so it can be assigned to the right package and communicated clearly to the right upstream project. -- 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/1837683 Title: Screen stops updating after about 8 hours - (EE) modeset(0): present flip failed To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/1837683/+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
