Improvements on gyro auto rotation for ACER 1825
In two old posts I described, how you could use the gyro sensor of the Acer 1825 for auto rotating your screen and how you could enable and disable this feature with a special button.

A user (perpe) from http://ubuntuforums.org/showthread.php?t=1486671&page=13 found out, that in windows the gyro sensor is enabled and disabled with some special keyboard events.
He found these keyboard events after doing a bios update to version 1.3127. Because of some problems I always did this update and could not check if the presented procedure works with older bios.
Make the special key commands usable:
You need to specify the keycodes for these commands in your /etc/rc.local
Next update both old scripts:
/usr/bin/gyro-auto-rotate.run

I use a tool for displaying me desktop notifications if gyro rotations is enabled or disabled. If you want to use it, you need to install the package libnotify-bin with
sudo apt-get install libnotify-bin
if you don’t want the feature please uncomment all lines with notify-send.
After that you need to update your key-bindings in gnome-keybinding-properties.
Take a look at my configuration:
you need to call the script gyro-key.run one time with parameter deactivate and one time with activate to enable and disable the gyro auto rotation. See example on the screenshot.
The backup-button is now free for other commands. I use it as button for fullscreen-mode.
[…] my last post I explained were you found a tutorial for installing a real multitouch driver for the ACER 1825 and […]
I did not like the idea of dedicating the only button in converted mode to a onscreen keyboard.
So i added an entry for the onscreen keyboard to the gnome menu under acessories. Then i added the onscreen keyboard to the Favorites in netbook-launcher with the command:
netbook-launcher –add-favorite /usr/bin/onboard
and set the P-button to execute: netbook-launcher –show-favorites
Now when i hit the P-button, the favorites pop up and i can select from the applications scripts …. whatever i want ^^

Interesting approach, but check the improved again script:
http://www.ceh-photo.de/blog/?p=336 It places and resizes the keyboard and the current active window for nice access.
Found an issue with your script.
The part:
———————-code———————————
xinput set-prop “$id” “Evdev Axis Inversion” 1, 0
xinput set-prop “$id” “Evdev Axes Swap” 1
xinput set-prop “$id” “Evdev Axis Calibration” $caliby $calibx
;;
right)
xinput set-prop “$id” “Evdev Axis Inversion” 0, 1
xinput set-prop “$id” “Evdev Axes Swap” 1
xinput set-prop “$id” “Evdev Axis Calibration” $caliby $calibx
esac
}
—————————–\code————————-
does not work on my lucid install with single touch Cando driver setup:
——————————\xinput list——————–
:~$ xinput list

⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]

————————–\xinput list————————————-
but if you change it to this for use with cando driver:
————————–switched caliby & claibx ———————-
;;
left)
xinput set-prop “$id” “Evdev Axis Inversion” 1, 0
xinput set-prop “$id” “Evdev Axes Swap” 1
xinput set-prop “$id” “Evdev Axis Calibration” $calibx $caliby
;;

xinput set-prop “$id” “Evdev Axis Inversion” 0, 1
xinput set-prop “$id” “Evdev Axes Swap” 1
xinput set-prop “$id” “Evdev Axis Calibration” $calibx $caliby
esac
}
————————–\end—————————–
it works for use with Lucid Cando kernel 2.6.35 without messing up calibration.
Notice, only $calibx and $caliby variables have been switched to stay the way they are in normal and inverted mode.
This did the trick for me 🙂

I wrote a udev rule to change the owner of the gyro device automatically.
Simply make a file in /lib/udev/rules.d/ called 30-g-sensor.rules
(you need root provileges for that)
and put:
KERNEL==”i2c-[0-7]”, OWNER=”user”, GROUP=”user”
in it, while replacing user with you username.
then reboot or run:
sudo service udev reload && sudo udevadm trigger
Hey thanks for that reply! I did not have problems with the rights but some others have it.
