Does this keyboard work on the console? It kind of does - everything except the modifiers (shift,alt,delete) does. Anyway, do this: 1. Go to the text console and login as root (alternatively login as another user and use sudo su to become root). In order to go to the text console normaly you would use Ctrl+Alt+F1, but if the faulty Ctrl and Alt make this combination not work, then start a X terminal emulator (i.e. xterm, xrvt, gnome-terminal or konsole) and use the command sudo chvt 1. I had no problem getting to the ttys, however I do not understand why it would be necessary to run the comands from the text mode console. 2. Run showkey -s. 3. Very quickly press Shift, press A, release Shift, release A. The output for this is the following : 0x2a 0xaa 0x1e 0x9e 4. Very quickly press Shift, press Q, release Q, release Shift The out put of this was the following : 0x2a 0xaa 0x10 0x90 5. Wait 10 sec to get the command prompt. 6. Repeat the same but this time use showkey -k. For the first combination the output is : keycode 42 press keycode 42 release keycode 30 press keycode 30 release I should point out that I was trying this many times and every time, despite using the order : shift, a, release shift, a For the second combination output was very similar : keycode 42 press keycode 42 release keycode 16 press keycode 16 release Just in the previous I tested this quite extensively and I still got the above. 7. Send the result. Anton Zinoviev As I pointed out in the first report it seems that any key pressed while the modifier key is pressed cancels the modifier. I noticed it when I try to use xkeycaps to try and fix things. -- Regards, Jacek Leśniewski -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of unsubscribe.

The output for this is the following : 0x2a 0xaa 0x1e 0x9e These are the scancodes that the keyboard sends to the computer (after some minimal processing by the kernel). 0x2a is the pressed Shift and 0xaa is the released Shift - before A is pressed (0x1e). So I see only three possibilities - 1. the keyboard is faulty or 2. the Bluetooth keyboard standard has redefined somehow the hardware protocol of the comunication between the keyboard and the computer and the keyboard driver doesn't support this new protocol or 3. that this keyboard generates the hardware interrupts in a strange way that confuse the keyboard driver of the kernel. Because of this I am reassigning the bug. Hopefully the kernel developers will know what to do with this bug.

Anton Zinoviev The keyboard cannot be fault as it works perfectly well in windows (annoyingly). Further more I only just bought it a week or so ago. It also worked well with an Android found (Samsung Galaxy S) However I'm not sure whether the modifiers worked propely. As to the bluetooth protocol it might in deed be the problem. PS. Do I have to reassign the bug or change its title, and if I do how do I do this ? Anyhow thank you for the quick response. -- Regards, Jacek Leśniewski -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of unsubscribe. Trouble?

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. http://ubuntuforums.org/showthread.php?t=1355660 http://ubuntuforums.org/showthread.php?t=1368160 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. -- System Information: Debian Release: wheezy/sid System: Aptosid 2011-01 Γῆρας APT prefers unstable APT policy: (500, 'unstable') Architecture: amd64 (x86_64) Kernel: Linux 2.6.37-1.slh.1-aptosid-amd64 (SMP w/2 CPU cores; PREEMPT) Locale: LANG=en_GB.UTF-8, LC_CTYPE=en_GB.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Versions of packages keyboard-configuration depends on: ii debconf 1.5.38 Debian configuration management sy keyboard-configuration recommends no packages. keyboard-configuration suggests no packages. -- debconf information: keyboard-configuration/layout: keyboard-configuration/xkb-keymap: us * keyboard-configuration/variant: USA debian-installer/console-setup-udeb/title: keyboard-configuration/unsupported_options: true keyboard-configuration/ctrl_alt_bksp: false keyboard-configuration/variantcode: keyboard-configuration/other: keyboard-configuration/optionscode: lv3:ralt_switch,compose:lwin keyboard-configuration/modelcode: pc105 keyboard-configuration/unsupported_config_options: true keyboard-configuration/unsupported_config_layout: true keyboard-configuration/toggle: No toggling keyboard-configuration/compose: Left Logo key keyboard-configuration/switch: No temporary switch keyboard-configuration/altgr: Right Alt (AltGr) keyboard-configuration/unsupported_layout: true * keyboard-configuration/model: Generic 105-key (Intl) PC -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of unsubscribe.
