yep. Seems to work. :) 

thanks for the patch!

I need to do some more testing... not sure I had any 3d stuff running

There _might_ be a problem with the DRI install.sh script being so paranoid
about alien libGL libs that it moves yours somewhere else...  I'm going to
fix that soon.

If you can see a message in your XFree86.log like this:
(II) RADEON(0): Direct rendering enabled after VT switch
after switching back from the console, it means everything is hunky dory.
Just remember to test for the radeon usecount before you suspend...

Thanks,
Charl

It does in fact do that; however, running "ldconfig" as root seems
to clear up any linking errors.

Re: Re: Compaq Presario 2800T

[Sourav K Mandal]

Hi,

So I upgraded to the acpi-20020726+swusp11.  Nothing much 
has changed; however, I did develop a workaround for the hang
when resuming from the suspension.  I was able to deduce that 
ALSA was the culprit, so I simply shutdown/start ALSA in my 
suspension script.

The hangs on resume started with the patching of the DSDT. 
ACPI with the patched DSDT is producing the following error
(excerpted from dmesg):

Executing all Device _STA and_INI methods:...evrgnini-0243:
*** Error: Could not install Pci+config handler for C03C, 

This error is repeated thrice.  Since my sound component
(ADI SoundMAX, Intel 810) is PCI, I wonder if it's related?
I'm not sure how to eliminate the error ... I could send
my ASL DSDT to somebody who might be interested.


Regards,

Sourav

Just thought I would update everyone on my presario 2800 acpi
progress. 

Once I modified the dsdt with the correct tool (thanks for the
pointer), most everything is working!

Software suspend still seems to work well. 

Some questions: 

With the processor information in /proc/acpi/processor, I have:

    T6:                  75%
    T7:                  87%

The only thing I can change is the "throttling" setting. Is that just
cpu idling? or something else? 

It doesn't seem to want to let me change "power" or "performance". Any
ideas? 

Also, the brightness buttons (Fn-F7 and Fn-F8) work ok in the bios,
but don't seem to do anything once linux is booted. Is that ACPI
related? Something else?

Also, this is a interesting one... the lid button is registered and it
shows an ACPI event each time it closes or opens, but it doesn't show
if it's closed or open, just a incremented number. any way to tell
which state the lid is in? ie, a close, open lid cycle shows as: 

[Sat Aug  3 16:04:55 2002] received event "button/lid C11D 00000080 00000021"
[Sat Aug  3 16:04:55 2002] completed event "button/lid C11D 00000080 00000021"

[Sat Aug  3 16:05:01 2002] received event "button/lid C11D 00000080 00000022"
[Sat Aug  3 16:05:01 2002] completed event "button/lid C11D 00000080 00000022"

so, 21 and 22... next time will be 23 and 24, etc.. Do I just odd/even
to detemine if the lid is closed?

Thanks for all the help on this list... you guys have been great. I am
quite happy with the laptop now.

I have seen observed all the behaviors you have on my own 2800 except
this one -- my brightnesses work correctly, even over reboots, i.e.
brightness values with and without AC adapter are stored and restored.

FYI, I'm using linux-2.4.18+acpi-20020726+swsusp11+packet-cd

Yeah, trying it out myself it seems like a DRI thing.  Try 
turning off DRI in your XF86Config and see if it helps. You might have
to reboot ... DRI doesn't work when coming back from suspend, and some
things don't work once you run DRI.  For me, once I run DRI the
backlight refuses to turn off on lid close -- reboot fixes this. 

If that doesn't work, try switching to a text console.

I have yet to apply Charl's patch, and so I alternate between DRI and
no-DRI XF86Configs.  I don't know if the patch fixes the backlight thing
...

FWIW, my dim/bright keys (Fn-F6 and Fn-F6) always work and the brightness
level is even retained across reboots.  The binaries on
http://cpbotha.net/dri_reinit.html have been updated, although I doubt that
thet changes have to do with your brightness settings.

There is more detail at cpbotha.net/dri_reinit.html.

Basically, Michel Dänzer has re-engineered my concept to make it more
stable.  You can now do things like run multiple DRI-capable servers at the
same time and switch between them... they will automatically switch between
hardware and software 3D depending on who's holding a lock on the Radeon
hardware.  My kludge could also do this, but would break under certain
circumstances.

The suspend/resume software is still more or less the same.

Well, I finally got around to upgrading to the newest one there (got
some more memory for the laptop and had to reboot anyhow)... 

I also did some debugging... 

The Fn f7 (dim) and Fn-f8 (brighten) and Fn-F4 (monitor) all work fine
when I first boot up. They also work fine if I start X with no DRM. If
I start X with drm, then they stop working and won't work again until
I reboot. 

Any ideas? Could be a XFree86 version problem? 

I am running RedHat limbo with XFree86-4.2.0-56 + your drm_reinit
modules.

Exactly what I'm getting, but with stock DRI modules.

Unforunately, not really.  :-(

My (layman's) guess is that it has something to do with the GPU's
power state.  The BIOS won't shut down the LCD until it's
satisfied with the Radeon's power state; once DRM is used
 the Radeon cannot enter an acceptable power state.

This is the inverse of the DRI-on-resume problem, that once
the Radeon is shutdown w/o reset, the DRM "parts" don't 
wake up properoly.

Just for clarity, on my laptop (which is not a Compaq, but a no-namer with
Radeon Mobility 7500 64MB) the bright/dim keys always work, DRI or no DRI.

If you experience this with stock XFree86 DRI as well, I would post a report
on xpert-72qDnkntNoRAfugRpC6u6w@public.gmane.org as well.  One of the ATI engineers is spending a lot of
time with these drivers and might have something to add to the equation.

The DRM wasn't designed for stopping/starting in mid-stride, which is why
we've made it so that it completely initialises/de-initialises during
VT-switch.  If certain remaining technical problems can be sorted out, this
might even make XFree86 4.3.0, at least until a more generic solution can be
implemented.

Good luck,
Charl

ok. I will try and test it later tonight and see. I can't remember if

buttons still don't work in a text console either. 
I might try with no DRI after a bit... enjoying the stability for a
few days. 

For the backlight I rescovered: 

http://fdd.com/software/radeon/

Tool to turn on/off the backlight. I set it up in acpid to turn off
the backlight when the lid closes and back on when the lid opens (as

I am running that patched radeon, and I can't do anything with

I don't have my laptop with me, but I just did the following text
substitutions (using sed) on the ASL DSDT:

"*PNP" -> "PNP" (per Christoph)
"C11C" -> "BAT1"
"C11B" -> "BAT2"
"C11A" -> "ACAD" (I'm not sure about this one -- 
                  check your /proc/acpi/ac_adapter dir first)

It was working well until I fixed my DSDT!

Interesting that you have a /proc/acpi/sleep entry; I don't.  I've
been using "echo -n '1 0 0' > /proc/sys/kernel/swsusp".  It just
occurs to me that I should turn on the debugging bits and see
if I can understand what's wrong ...

This should be repaired once you tweak the DSDT.

Please report back how it goes -- I'm using the 20020709 series of
patches on kernel 2.4.18, so if everything works out for you I
might upgrade to 20020726.

You should upgrade to 20020726 or edit your .config so that
CONFIG_ACPI_SLEEP is activated.  When I _didn't_ do this, i.e. only swsusp
but no /proc/acpi/sleep, suspend/resume stopped working on my laptop as well.

I did put CONFIG_ACPI_SLEEP in my .config, but it didn't work:
no /proc/acpi/sleep, and resume locks.  (Were you simply unable
to suspend, or did you have the same problem where the resume
locks?)

PS:  It has nothing to do with X, so it has nothing to do with the
Synaptics driver.

As far as I can remember, the resume locked...  but I'm a bit vague on this,
as this happened in a period when I was experimenting with 98239849832 other
things to get the laptop working to my taste. ;)

Is this the wrong format from acpidmp?

Are you using the acpi-swspend patch? I am using the

Woah, I think you made the same mistake I did -- the utility
you're using gives a hex dump rather than ASL.  Use this 
utility:

Yes -- but rev. swsusp9 versus acpi-20020709.  I will upgrade
both.

Cool -- I'll try it out once I get the resume issue resolved.
