Tried the steps to boot with LID close. found that LID close until the BIOS logo show, unless the laptop will shut down.
Then all work good. GDM shows on external monitor. Test with typec/HDMI/thunderbolt-dock-typc external monitor, thunderbolt dock is always connected. BIOS should be default setting with optimized enabled, secure boot is disabled. GPU is hybrid. Only difference should be BIOS. You are using a withdrawn BIOS version. Could you try the new one? https://pcsupport.lenovo.com/us/en/products/laptops-and-netbooks/thinkpad-p-series-laptops/thinkpad-p1-gen-2-type-20qt-20qu/downloads/DS540308 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1876741 Title: Lenovo X1 boot crash with HDMI cable attached and laptop lid closed To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1876741/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
