What is AGP.VID, I didn't find any information regarding VID in ACPI
spec 2.0b.

I think video driver should be responsible for turnning on/off console,
becuase they have chance to run when entering/leaving S1/S3.

Thank you for your reply.

AGP is clearly the onboard video device. From the dsdt, AGP is a device, and
VID a subdevice. It appears that the VID is adhering to the Appendix B of
the 2.0c specs (switching video outputs)

>From looking at the DSDT \_SB.PCI0.AGP.VID is only being notified of
lid open/close event. Which makes sense - you might want to enable the
external CRT at that time. I am currently investigating if the Dell BIOS 
requires one to enable the output display on waking. If so - the dsdt is not
doing it. (I need to check the display status bits after restore).

I've come to the same conclusion.  I've discovered that 
the blanking is caused by the machine disabling the LCD backlight on restore.
(radeontools-1.2 figured that out). 

I need to figure out now if the vga handler (VESA) interface is doing the 
right things on power restore. There was another thread about someone
else having the backlight remain on on S1/S3 invocation - and that the driver
was disabling hsync/vsync. If everything is Kosher there - then maybe I 
need a radeon specific blanking hook to follow the vga driver.

Thanks again - I will keep everyone posted.

Ezra

I have the same entry in my thinkpad R32.

Mine seems to follow the "display specific methods" that are described 
in section B.4 (I have the 2.0c spec in fron tof me now).

Hmm, ACPI should interact with the Linux video subsystem.

DELL inspiron 8200 fails to restore console after S1/S3

[ezra peisach]

Testing w/ the 2.6.0 kernel and the 12/03 patches to acpi, the following
happens w/ the stock DSDT A10 on an inspiron 8200:

The display is a radeon 9000....

The following occurs if X is not running. (init run level 3)

If one moves to power state: S1 - the screen does not go blank (text
remains) When power is restored, the machine accepts keyboard input,
but the screen then goes blank.

If one move to power state S3 - screen goes blank. Power restoration
flashes the screen then remains blank.

When X is running - sometimes the screen is restored, sometimes
not. I.e. sometimes it comes out w/ garbage.

Based on the bugzilla.kernel.org - bug 605 - discusses backlight not
going off.  There is a comment that ACPI may not be responsible for
this - the gfx driver is.

When X is not running - there isn't a gfx driver - except the kernel.
Do we need an OS specific handler to receive notifications of 

\_SB.PCI0.AGP.VID

and do the right thing?

Perhaps the agp driver is the proper place.... I suspect it may be a radeon 
specific thing...

For the X case - maybe it needs to observe the acpi events - not just apm.

Anyone have any ideas?

Ezra

I got a similar problem on 2.6.0 with no ACPI patch, while entering in
S3 with (and not S1): I've a clean resume, but the screen remains blank,
while keyboard inputs are accepted. I posted my problem here
>
http://sourceforge.net/mailarchive/forum.php?thread_id=3676335&forum_id=6102

Sleeping in S3 from an terminal in an X session doesn't restore the X
session, but starting the shutdown (always without seeing my typing),
restore tty1 showing normal messages on shutdown (like "Shutdown called
from..." and "acpi_power_off_called"), as usual when I press the
'power-button' from an X session.

I'm on an ASUS M3410C (M3N): http://luca.pca.it/projects/asus/m3410c.php
Attached my DSDT from 'cat /proc/acpi/dsdt > dsdt.raw'. Maybe it could
be useful.

Please excuse me if the problems aren't related.

Thx, bye,
Gismo / Luca
