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,
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.
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
this is interesting, I never saw something like that for vaios and
linux.
Its not a big problem, its just annoying...
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.
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?
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.
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?
regards
Sebastian
