That is right, my startup script only work with Norberts kernel module
loaded with acpi_osi="!Windows 2006", I will next make a better script
that will find out what kernel module is loaded by default to become
more general and a little bit smarter.

That is nice but I have tried that already and it does not land
in /proc/cmdline

this:

first change /etc/default/grub:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_backlight=vendor"
GRUB_CMDLINE_LINUX="acpi_osi=\\\"!Windows 2006\\\""

then execute:
sudo /usr/sbin/grub-mkconfig

now /boot/grub/grub.cfg has the right entries


but

after a reboot, it is wrong again...


Only pressing 'e' in the grub menu and edit the command line by hand
(change " into \")

No, it can/does not that way.

Thank you for your report, respawning was not realy necessary ;-). It is
removed now, update it (or remove 'respawn' out of the
file /etc/init/switch-x-to.conf) Then this syslog entries will not apear
no more.
