Kako je MS zeznuo stvar s laptopima

Konkretno to znači da na novim laptopima neće više raditi prečac za prebacivanje slike na projektor, nego će efekt biti kao da ste stisnuli slovo P
Takvim akcijama MS nesvjesno (ili svjesno) zaključava hardver na Windowse...

Hi,

The main cause of the problem is ACPI.

ACPI contains some embedded code that is run/interpreted by the OS under certain conditions, called "AML" (ACPI Machine Language). So that this AML can support different OSs "better", the OS tells the ACPI what it is and depending on what the OS says it is the AML behaves differently. In this case, if the OS says that it is "Windows 7" then the AML modifies the behaviour of the "win + p" to better suit Windows 7.

Why is this a problem? Because Linux lie to the AML and say that Linux is "Windows 7", when obviously Linux isn't.

So, why aren't I blaming Linux for lying to the AML? This is because ACPI/AML is a disgusting overcomplicated mess; and if Linux told AML "I'm Linux" then the AML would disable most of the nice features.

Basically, Linux doesn't have much choice - the design of ACPI (and the resulting AML created by firmware) is broken, and has been since it was created. The OS should say "I support ACPI/AML version X.Y.Z" (and differences in AML behaviour should be specified properly in the ACPI specification), but ACPI was never designed like that.

So, it's ACPI's fault. ACPI is designed by a committee (not unlike the proverbial camel); therefore it's this committee's fault. Guess who the main participant is in this committee...

However, it's important to realise that the "win + p" problem is only a symptom of a much larger problem (ACPI) and that the real problem has been lurking for about a decade now, and will probably surface again (and again and again, each time a new version of Windows is released).

"There's a range of ways we can fix this, although none of them are straightforward and those of you who currently use left-Windows-p as a keyboard shortcut are going to be sad. I would say that I feel your pain, but my current plan is to spend the immediate future getting drunk enough that I stop caring."

Dakle, osim x.org treba ponovno napisati i ACPI? Eh,... No postavlja se pitanje što je sa APM-om? Bi li prelazak na APM možda riješio taj problem i općenito se pokazao robusnijim?

Ma sve što Windowsi ne koriste po defaultu, ni proizvođači hardvera ne održavaju, ne rade kvalitetno... da rade, Linux se nikad ne bi trebao ACPI-u predstavljati kao Windows... kava
