hm flag

I have tried

acpi_osi='Windows 2015' in /etc/default/grub file; GRUB_CMDLINE_LINUX_DEFAULT="acpi_osi='Windows 2015'"

After update-grub an reboot machine

I ran: sudo dmesg |grep -i add

But is Missing,

ACPI: Added _OSI(Windows 2015)

Any idea, why?

solution from kernel parameters admin-guide:

GRUB_CMDLINE_LINUX="acpi_osi=! acpi_osi=!* acpi_osi="Windows 2015""

or simply:

GRUB_CMDLINE_LINUX="acpi_osi=! acpi_osi="Windows 2015""

Now i see in bootlog::

ACPI: Added _OSI(Windows 2015)

Thx

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
