Bug#614936: keyboard-configuration: Modifier keys (ctrl, shift, alt) not working - Bluetooth keyboard
Package: keyboard-configuration
Version: 1.69
Severity: important
Tags: sid
The problem basicly is that when pressing any of the modifier keys they do not
'modify' the keys pressed simultaneusly with them.
Having wondered around looking for the solution I ended up finding out that
when I press any of the modifiers the next key-press cancels them. This does
not happen when pressing any other two keys simulatneusly - they do result in
two signals being send with out canceling each other, what excludes the
possibility of my keyboard not supporting multiple keypresses.
Anyhow having found a couple threads on the following forums regarding the
problem and not finding a satisfying solution I wanted to find a solution that
actually works.

I thought of some possibilities of the causes of the problems, however I cannot
really solve these by myself :
1. Bug in keymap - I've got no idea what type of a bug could produce such
effect but it might be possible.
2. Kernel misinterpretation - it might be a problem with the kernel
interpreting the key pressed on the keyboard and thus making the modifiers
malfunction.
3.Bluetooth adapter controller *bluez - this is highly unlikely as I have tried
another bluetooth keyboard on this system and there was no problem using it -
all modifiers worked perfectly. (both of these connect perfectly and all keys
accept the modifiers work normally)
4. Microsoft based hardware - as there is no problem using the keyboard on
either Win Xp or the 7 there might be a special code written for correctly
interpreting the key presses of the modifiers.
The problem is that even after "disabling" the modifier by a key press and then
letting off the modifier no code in xev is generated. This excludes the
possibility of writing a small code that would enable and disable the modifiers
properly.
In the threads I mentioned almost all the data is there if anything is needed
please let me know. I don't however have a rocketfish keyboard but a Lenovo
A300-K BT Keyboard
I hope there is a possibility of finding a fix/solution for that other than
sticky keys because they just get on my nerves really badly all the time.
Any help would be really appreciated.
