ACPI - DOS - 2.6.10

ACPI - DOS - 2.6.10

[Lukas Hejtmanek]

Hello,

since 2.6.10-rc1 display switch button stoped to work. I have ACPI video
compiled in, it displays: DOS setting: <1>

Any value written to this file does not get it work. ACPI event is generated:
[Mon Dec 27 00:07:32 2004] received event "video VGA 00000080 00000000"

Any suggestions? I can provide /proc/acpi/dsdt if it helps.

The DSDT shows that:
In _DOS:
                     If (LNot (LLess (OSYS, 0x07D0)))
                    {
                        Store (0x00, DSEN)
                    }
And in _Q0E,  if DSEN is 1 then, BIOS will automatically handle  dispaly switch,
otherwise, it just generate Notify event to OSPM, and rely on driver to handle it.
However, there don't have _DSS in DSDT , which is requred for acpi video driver to handle display switch.

Could you try kernel option "acpi_osi=" 

Thanks,
Luming

Nothing changed.

Btw, there is a touchpad switch (to turn it off/on) that does not work any more
either.
