I've downgraded to firmware 1.73 through the Gnome Firmware application. The issue is not present on this version and I can reboot like a normal person. I suppose I can figure out if it's 1.74 or 1.75 that breaks it.
Not really sure where to report this, I don't think it's Ubuntu specific, I use Arch and only tried Ubuntu to see if the issue exists here, it doesn't seem to exist on Windows 10, or at least I didn't notice while I was running that earlier this month. Maybe we should report here? https://github.com/fwupd/firmware-lenovo-thinkpad To be safe, I've been factory resetting the bios when flashing just in case something weird gets brought over. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1890415 Title: Lenovo ThinkPad X390 won’t boot while plugged in To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1890415/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
