ACPI Problems on Sony Vaio SZ61MN, no brightness ctrl, no power button
Hi there!
First i hope my other messages have realy disappereard. I send them yesterday from a windows machine and as described in the FAQ it seemed to be blocked because of the charset. If by any chance that message arrives please excuse it and ignore it!
My Problem exists on a Sony Vaio Laptop with the modelcode SZ61MN/B. I am currently running Archlinux with a 2.6.25.11-1 kernel. Most things on the notebook seem to be working, even the lidswitch is recognized.
Problems are the non-working power button, thats a real problem, just annoying, and what realy is a pain, the backlight brigthness is not adjustable, so i always get a nice suntan from the screen. That realy sucks at night...
I tried for about a week now to find a solution and i worked my way through all of the possible solutions called sony-laptop, sonypi, sony-acpi but none of them worked for me. The web also holds some other persons with the exact same problem. I also tried to contact the maintainers and writers of that programs but i got no reply till now and no solution. So this is my last chance to get an answer here and i hope you can help me!
As i am not that of a pro linux user, i am not quite sure what information you would need to possibly help me. Please tell me what info i can provide to make the case clearer!
kind regards
Sebastian

Problems are the non-working power button,
what do you mean by non-working power button? Pressing the power button doesn't power off the laptop, right? what if you press it for four seconds?
please run "grep . /sys/firmware/acpi/interrupts/*" both before and after pressing the power button and attach the result.

what did you get?
empty /sys/class/backlight/ entry with any of these drivers loaded? or the backlight I/F exists but they don't work for you?

Yes, youre right, pressing the button has no effect. Pressing 4 seconds powers off the laptop. Is that done via acpi too? Thought that was a hardwarething. Uploaded both outputs here: http://www.twisted-artwork.de/vault/linux/powerbutton.txt

As i am not sure if its wise to paste it here, i just uploaded it to my webspace, its quite a long file. (And as i remember attachments on emails are not allowed on mailing lists?)

The backlight files exist but they dont change anything. When i use the sonypi driver i can change some of the stuff with the program spicctrl. Powering of the internal devices works, adjusting fanspeed works, adjusting backlight just has no effects.

Did that too a few days ago, but got no answer, maybe i got the wrong adress.
Thanks for your help, i hope it doesnt take too long to solve this, cause in the meantime i am forced to use Windows when i am on the road, caus it has nearly twice the runtime on battery... :)

The SZ series have a stamina/speed switch switch between 2 video cards. Usually one is an NVidia (for speed) and one is an Intel (for stamina). On the NVidia there is nothing we can do (you can try nvclock or any nvidia proprietary tool as documented on my wiki[1]), while for the Intel card it's a different story (again documented on my wiki). If you have no luck with the sony-laptop provided backlight control you can try xbacklight that, as far as I can see[2], should work on your Intel chipset.
hope this helps

GREAT! [2] helped! Now i can change the backlight with xbacklight -set value.
As you said this only works for the intel chipset with is the graphic adapter i use when i am using the laptop mobile. So its annoying that i cant change the brightness wit the nvidia card but not as much of a problem as it was with the intel chipset. As the nvidia driver is a propietrary one, i dont think that is a thing i or anyone here can solve?
Thank you so much! Is the brigthness issue now still a bug or should i delete it from bugzilla?

Sebastian

Hi,
the backlight now is working with the Intel chipset. But the workaround had some sideeffects: Now the lidswitch is unfunctional. :/
I tried to find out if it works by running acpi_listen but the lidswitch generates no events...
Any ideas?
