Kay Müller, thank you for reporting this and helping make Ubuntu better. 1) As per your logs, you don't have a nvidia graphics card installed. Hence, could you please uninstall the nvidia software you installed and advise if this is still reproducible?
2) If still reproducible, 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 ** Tags added: bios-outdated-1.28 ** Changed in: xorg (Ubuntu) Importance: Undecided =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/1707632 Title: Connecting HDMI freezes everythin Status in xorg package in Ubuntu: Incomplete Bug description: I ones install some invidia package but I could fix that.
