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.<\/p>\n

A user (perpe) from http:\/\/ubuntuforums.org\/showthread.php?t=1486671&page=13<\/a> found out, that in windows the gyro sensor is enabled and disabled with some special keyboard events.<\/p>\n

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.<\/p>\n

Make the special key commands usable:<\/p>\n

You need to specify the keycodes for these commands in your \/etc\/rc.local<\/p>\n

#button P<\/div>\n
#STRG+ALT+NB_ENTF<\/div>\n
setkeycodes e070 112<\/div>\n
#button backup<\/div>\n
#XF86Launch5<\/div>\n
setkeycodes e062 184<\/div>\n
#tablet mode key<\/div>\n
#XF86MenuKB<\/div>\n
setkeycodes e039 185<\/div>\n
#laptop mode key<\/div>\n
#0xb8<\/div>\n
setkeycodes e001 176<\/div>\n

Next update both old scripts:<\/p>\n

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<\/p>\n

sudo apt-get install libnotify-bin<\/p>\n

if you don’t want the feature please uncomment all lines with notify-send.<\/p>\n

After that you need to update your key-bindings in gnome-keybinding-properties.<\/p>\n

Take a look at my configuration:
\n\"\"<\/a><\/p>\n

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.<\/p>\n

The backup-button is now free for other commands. I use it as button for fullscreen-mode.<\/p>\n","protected":false},"excerpt":{"rendered":"
