I installed an older kernel, and was able to boot and log in. But the external display (HDMI) still didn't work. In desperation I went to Settings -> Users -> Automatic Login.
And now everything works. Apart from the fact that my computer can be used by anyone. So it was a mistake on my part to tag this as a xorg problem. It's clearly to do with the login of the window manager. -- 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/1818899 Title: After Ubuntu Base update tp 4.15.0-46-generic computer freezes after login To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1818899/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : [email protected] Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
