Hello Christopher, I updated to the bios version 2.61:
root@grueneerle:~# dmidecode -s bios-version && dmidecode -s bios-release-date GAETA1WW (2.61 ) 09/14/2015 The fix in version 2.61 was simply a security update: Version 2.61 UEFI: 2.61 / ECP: 2.61 [Important] Fixed security vulnerability (LEN-2015-002 and other fixes). (Note) If the UEFI BIOS has been updated to version 2.61 or higher, it is no longer able to roll back to the version before 2.61 for security improvement. - http://support.lenovo.com/de/de/products/laptops-and-netbooks/thinkpad-edge-laptops/thinkpad-edge-s430/downloads/DS029727 This problem still remains, so I will mark this as confirmed. ** Changed in: xorg (Ubuntu) Status: Incomplete => Confirmed -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1504220 Title: Black screen after "prime-select nvidia" and restart of lightdm/reboot To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1504220/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
