ACPI spec defines _ROM as "This method is used to get a copy of the display devices’ ROM data". In this case, it is used to get VBIOS (ex. VGA's configuration) from ACPI BIOS AML code. As it fails, OS is not able to get such configuration information.
I tried nvidia-prime and switched between nvidia and intel VGA, and the switching did happen according to its system indicator, but I am running glmark2 in both VGA modes in order to see whether the switching is indeed occurred. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1364748 Title: [Lenovo ThinkPad T440p][10de:1290] switching nvidia graphic card raises fwts high failure To manage notifications about this bug go to: https://bugs.launchpad.net/hwe-next/+bug/1364748/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
