Automatic screen rotate for N810

2008-04-16T09:45:00.011+03:00

After testing the taskbar applet to rotate the screen in my N810, I thought it would be much easier to use the power key to initiate rotation.

Also when opening the keyboard, I wanted the screen to automatically rotate to landscape to be able to see what I was writing and return to portrait mode when the keyboard is closed.

Now it can be done:

This package provides the following functions:
-screen is rotated to portrait / landscape mode by
a) pressing the power key
b) pressing and holding the Application switch key for more than one second.

If the keyboard is opened when the screen is rotated to portrait mode, it will be rotated to landscape mode.

When the keyboard is closed, the screen is rotated back to portrait mode, if it was already in portrait mode when the keyboard was opened.

You will need to install the xserver-xomap with RandR support, as well as flash the kernel with RrandR support before this package will do anything. Since the updated components can't be a dependecy, you are required to do it yourself.

This one-click-install will provide you with an updateable xserver-xomap if you are not already using it.

After the package installation is complete, update the xserver-xomap by either the application manager or apt-get.

Then flash your N810 with this kernel and reboot to complete the installation

If you do not know how to flash the kernel or update the xserver-xomap, you are advised not to install this package at all, as you may brick your device while experimenting.

The RandR supporting kernel and xserver-xomap are provided by http://sse2.net/rotate/

If you don't like to have the power menu appear when using the power key to initiate rotation,
edit /etc/mce/mce.ini:

PowerKeyShortAction=disabled
PowerKeyLongAction=menu
PowerKeyDoubleAction=menu

Then you can rotate the screen with a short press, but still can access the menu with long press, or double-clicking it.

Samba messages to NIT

Samba messages to NIT

In your Linux desktop that gets the actual samba messages:

edit /etc/samba/smb.conf


message command = /bin/sh -c '/usr/bin/linpopup "%f" "%m" %s;sudo -u your_username /usr/local/bin/n810sambamessage "%f@ %m says: $(cat %s)";rm %s' &

restart samba


sudo /etc/init.d/samba restart

sudo visudo


nobody ALL=(your_username) NOPASSWD: /usr/local/bin/n810sambamessage
nobody ALL=(your_username) NOPASSWD: /usr/bin/aplay

create a file /usr/local/bin/n810sambamessage


#!/bin/bash
ssh -x root@ip-or-hostname-of-the-NIT /usr/local/bin/sambamessage $@

make it executable


chmod a+x /usr/local/bin/n810sambamessage

create rsa key


ssh-keygen -t rsa

copy the key to the NIT


ssh-copy-id -i ~/.ssh/id_rsa.pub root@ip-or-hostname-of-the-NIT

In the tablet:

create a file /usr/local/bin/sambamessage


#!/bin/sh
message="$@"
run-standalone.sh dbus-send --print-reply --type=method_call --dest=org.freedesktop.Notifications /org/freedesktop/Notifications org.freedesktop.Notifications.SystemNoteDialog string:"$message" uint32:0 string:'OK'

make it executable


chmod a+x /usr/local/bin/sambamessage

Now, when your desktop receives a samba message, it will also be displayed in your NIT when you are in the same network.

Pipe, tab and dollarsign for the hardware keyboard.

2008-04-09T15:12:00.002+03:00

pipe tab and dollarsign for the hardware keyboard:
vi /usr/share/X11/xkb/symbols/nokia_vndr/rx-44

In section:

partial alphanumeric_keys
xkb_symbols "fisenoda" {
name[Group1] = "Finnish/Swedish/Norwegian/Danish";


   key   {       [       comma,          semicolon,      bar,        bar    ]       };
   key   {       [       period,         colon,          dollar,        dollar        ]       }

In section:

partial default alphanumeric_keys
xkb_symbols "base" {


   key     {    [    space,            space,            Tab,            Tab            ]    };

Now, pressing FN - , gives | (pipe)
FN - . gives $ (dollarsign)
FN-Space gives Tab.
