DPMS with ACPI

DPMS with ACPI

[Marc Giger]

Hi All,

I've seen that DPMS needs an APM conform BIOS. The call is made trough /dev/apm_bios. Is there an equivalent interface for ACPI? How can I use the DPMS feature with ACPI?
This would be a nice feature for my Laptop.

Thanks in advance

Marc

Proabably not the most helpful of comments... but DPMS seems to work
fine for me with ACPI rather than APM running things - I definitely
don't have /dev/apm_bios, but "xset dpms force standby" works properly,
to put the screen to sleep.

( Sony Vaio FX601 with Linux 2.4.19 + ACPI-20020821 and XFree86 4.2.0 )

On my Laptop not:-( 

It's also a Vaio GR114EK. This Vaio is a difficult case:-))

What i get with "xset dpms force standby" is:

X Error of failed request: BadMatch (invalid parameter attributes)
  Major opcode of failed request: 140 (DPMS)
  Minor opcode of failed request: 6 (DPMSForceLevel)
  Serial number of failed request: 10
  Current serial number in output stream: 12

I have activated the DPMS in XF86Config with 'Option "DPMS"'
What I get is:

....
Option "DPMS" is not used
<snip>
Open APM failed (/dev/apm_bios) (No such device)
...

Hi,

I Don't think that DPMS is really related to APM or ACPI. I cannot use ACPI on 
my desktop pc and I have a nVidia card using the XFree module provided by 
nVidia. APM gets disabled by this module:

kernel: apm: set display: Power management disabled

Nevertheless, "xset dpms force standby" is working properly without any 
Problems.
Perhaps DPMS is supported by APM, ACPI and/or the XFree modules...
