I'm not sure why you think it's only a security update, when it didn't specify what the "other fixes" were. As was previously advised to you in https://help.ubuntu.com/community/BIOSUpdate , not all BIOS fixes are documented in the change log, tested to your specific problem under the same operating system, or tested under your operating system at all. Unfortunately in this case, it didn't improve the situation. Despite this, could you please advise which nvidia driver package precisely you were using when this worked in Trusty? ** Tags added: regression-release vivid ** Changed in: xorg (Ubuntu) Importance: Low => Medium ** Changed in: xorg (Ubuntu) Status: Confirmed => Incomplete -- 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
