mark, thank you for reporting this and helping make Ubuntu better. 1) After the freeze, are there crash files in /var/crash?
2) Is this something that started to happen after an update? If so, which specifically? 3) To see if this is resolved in your release, could you please update your HWE stack as per https://wiki.ubuntu.com/Kernel/LTSEnablementStack and advise to the results? ** Tags added: bios-outdated-9hkt58a ** Changed in: xorg (Ubuntu) Importance: Undecided =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 Touch seeded packages, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1698354 Title: Xorg freeze Status in xorg package in Ubuntu: Incomplete Bug description: Screen freezes after logging on.
