PROBLEM: LCD display dead after ACPI suspend to RAM (S3)

Hi all,

on an ASUS M2400N [*] with both plain vanilla Linux Kernel 2.6.1 and
2.6.1 + acpi-20031203, the machine appears to suspend to RAM without a
problem and it also apparently comes back, but the screen is dead.

Here is the dmesg output for the suspend to RAM / resume cycle:

When trying to get/set the LCD status via /proc/acpi/asus/lcd, dmesg
shows

 Asus ACPI: Error reading LCD status
 Asus ACPI: Error switching LCD

Suggestions, anyone? If you need more info, let me know.

Regards,
Georg

Try passing acpi_sleep=s3_bios or acpi_sleep=s3_mode to the kernel on
boot - also try while running X, switch away before suspend and switch
back afterwards. The problem is that the kernel doesn't know how to wake
the video hardware back up after S3 - the kernel parameters are hacks
that try to provoke it back into life, and X is sometimes able to
reinitialise stuff itself.

Here is the dmesg once with s3_bios and once with s3_mode.

For both I still get

 Asus ACPI: Error reading LCD status
 Asus ACPI: Error switching LCD

The only difference is that for s3_bios, the backlight of the LCD is
one, but the screen only shows a pretty uninteresting pattern of three
or four lines.

Regards,
Georg

same here with an ASUS M3N (always a Centrino one), problem already
reported in this list here:

Finally, another user with my problem: IMHO this is indeed a problem in
te BIOS, because I starting having this error when I upgrade my M3N BIOS
from 0203A to 0205A. With this problem, I got even other errors like:

and when these errors occurred, keyboard doesn't respond, as it you're
keeping a button pressed. This is very annoying, if someone could please
tell me to whom I should address for this problem. On the other hand,
ALSA drivers works quite perfectly (except for some glitches on GNOME
and 'esd').

Thx, bye,

Just recompiled the 2.6.1 without internal acpi4asus and compiled
acpi4asus (current CVS) as a module. 

The module loads without problems and detects Asus M2N.

The problem remains -- here is dmesg:

But there is one difference: Now 

 cat /proc/acpi/asus/lcd

gives "1" (and no dmesg error message) and echoing values into it is
accepted without trouble. Unfortunately, the display remains dark. 

When booting with kernel option acpi_sleep=s3_bios, the background
light for the display comes on, but the display shows nothing.

If there is any more information I can provide, please let me know.

Regards,
Georg

well ! good point. So and version with the kernel, do you compile in the

 smb> So and version with the kernel, do you compile in the kernel ?

I'm, not sure what you are asking.

The kernel version is 2.6.1.

I've reproduced the problem with plain vanilla, ACPI version 20031002
and also after applying the latest ACPI 20031203 patch, which has
acpi4asus version 0.26.

Regards,
Georg

Re: PROBLEM: LCD display dead after ACPI suspend to RAM (S3)

[Sérgio Monteiro Basto]

well compile the kernel without any ACPI modules, compile all ACPI stuff
in the kernel.img .
Say Y to all that you used has modules (M) in kernel configuration (make
xconfig).

I'm not sure I understand what you are trying to tell me.

As I wrote: I compiled all the ACPI stuff into the kernel, only for
acpi4asus CVS that wasn't possible because I wasn't sure how to
properly integrate that into the kernel tree.

Georg

Thus wrote Georg C. F. Greve:

Swapping the asus_core.c from CVS with kernel's asus_acpi.c found in
drivers/acpi should suffice (the filename must remain asus_acpi.c of
course).
We'll have a new version released in a couple of days.

I thought that might work, but detected that there is an additional
#include statement for the kernel configuration, at which point I
wasn't entirely sure. 

Decided to do it as a module to exclude the possibility that any
problems I might have been seing were caused by my wrong addition of
the acpi4asus code, not the code itself.


 kk> We'll have a new version released in a couple of days.

Great, thanks. And it seems like the ACPI/APIC bug will be fixed in
the mainstream kernel, soon, too.

Georg

Where would the people maintaining the video driver have to look?

Interesting. I'll try that.

May this be a problem of the fb driver then?

Thanks for your input,

Exactly the same behaviour.

Re: PROBLEM: LCD display dead after ACPI suspend to RAM (S3)

[David Ford]

Try hitting the hardware function key that swaps the CRT/LCD and/or the 
function key that changes the font.

Works on my laptop.  Really annoying two-fold issue.  First, the screen 
is blank, second, I have to blindly run setfont to change the garbage 
font to a readable font.

I'm not running an fb, just an nvidia card in text mode on a Dell 
Inspiron 8200.

None of the keys make any difference.

PROBLEM: LCD display dead after ACPI suspend to RAM (S3)

[Alexei Gilchrist]

Hi, I can report the same errors (and failure of the solutions) on a 
panasonic W2 (Intel 855GM video card)

see http://bugzilla.kernel.org/show_bug.cgi?id=1877

(NB contrary to original report the keyboard and mouse do work after a resume)

This is particularly a problem as APM also fails, and the various suspend-to-disk
progs only work very intermittently, so the machine has to be rebooted from scratch
each and every time.

regards,

Alexei

So we have the video card in common, it seems.

I'll add my info to your bug report.
