On laptop Acer Timeline, Bluetooth switch changes brightness

oh, forgot one important bit - this is for 9.10, udev 147~-6.1

Thanks! Fixed upstream in commit d0a161c (I used a simpler patch).

Both, the posted patch and the patch applied as d0a161c, only apply to the Aspire 1810T, mentioned in the opening post. The exact same issue can be found on my Travelmate 8471 (also from the Timeline series) and probably others, so I'm reopening the bug

TravelMate 8471 fix committed to master (6ab861d).

I can confirm that this bug also affects the Acer Aspire 1810TZ.
Using a modified bugfix solves the problem for me:

Add /lib/udev/keymaps/acer-aspire_1810tz:
0xD9 bluetooth # (toggle) on-to-off

Add the following line in /lib/udev/rules.d/95-keymap.rules:
ENV{DMI_VENDOR}=="Acer*", ATTR{[dmi/id]product_name}=="Aspire 1810TZ", RUN+="keymap $name acer-aspire_1810tz"

Aspire 1810TZ fix pushed to master (f1707f1).

I did: "patch -p0 -i acer1810-keymap-fix" on my acer 1410, but problem persists.

BlaWiz: Please tell us the output of "sudo dmidecode -s system-product-name", i.e. what model exactly you're using. This string is used by the patch to identify the model and may differ a bit, which causes it to not work.

Same problem on my Acer 8571. The string is
TravelMate 8571

What have I to do? Where to get the patch from?

Beside that: I want the Acer come up with switched off bluetooth. Could find a file in /etc/ handling that, but I I chose the poweroff line I can't switch it on at all.
From my point of view, a Laptop should save as lot energy as it can.

arno: The hotfix would be to put the following line in the file /etc/udev/rules.d/96-bluetooth-hotkey.rules (doesn't exist, you have to create it with this line):
ENV{DMI_VENDOR}=="Acer*", ATTR{[dmi/id]product_name}=="TravelMate*8571*", RUN+="keymap $name 0xD9 bluetooth"

I didn't search for any options to turn it off, I just put the following snippet in /etc/rc.local:
for rfkill in /sys/class/bluetooth/hci*/rfkill*/state; do
  [ -f $rfkill ] && echo 0 > $rfkill
done

This has the same effect as if you pressed the bluetooth switch on startup.

This bug was fixed in the package udev - 151-1
