Bug Description

I recently upgraded from EDGY to FEISTY and am now experiencing the following behavior on my IBM (Lenovo) ThinkPad T43.

When i press the CAPS LOCK key, the NUM LOCK is also turned on (thus making my my keyboard unusable as half the keys go into numeric keypad emulation mode.) When CAPS LOCK is depressed, the NUM LOCK is not deactivated. The only way to de-activate the NUM LOCK is to press Shift + ScrLk (which is the normal way to activate/deactivate the NUM LOCK on this laptop).

The other issue that may or may not be related is that the NUM LOCK light at the top of the keyboard is always on when in FEISTY. Turning off the NUM LOCK functionality, does not turn off the light.

This is reproducible on this machine always and I have no idea how to fix.

I would be happy to provide any other information if required.

I didn't implicitly say the following points...

    This did not occur before the upgrade. All operation worked fine when I was working on Edgy

    No new packages or applications have been added to the system since the upgrade.

Another point, when i start up the machine, the NUM LOCK light is off. Once I log in, after putting in my password and hitting enter, the NUM LOCK light comes on and I must turn the NUM LOCK off to use my keyboard normally. The NUM LOCK indicator light never turns off after that point.

Thank you for taking the time to report this bug and helping to make Ubuntu better. You reported this bug a while ago and there hasn't been any activity in it recently. We were wondering is this still an issue for you? Can you try with latest Ubuntu release? Thanks in advance.

It was the last time I used Ubuntu. I had to go back to Windows when my company upgraded to Exchange 2007 and I could no longer access my email. Sorry, but I do not have a test box anymore..

This has been happening to me too. I have an IBM Thinkpad T41. If I dock it and use an external keyboard, the problem doesn't occur. However if I use the laptop's built in keyboard, pressing the CAPSLOCK button causes NUMLOCK to also turn on. Mousekeys (adaptive technology to move mouse with keyboard) is also mysteriously turned on when this happens.

It makes the laptop unusable.

Adam, I'm using 8.10, but this happened for me on 8.04 too.

Hi,

for me this bug happens too on Kubuntu 8.10 with KDE4 after I press Caps Lock. Before I used Kubuntu 8.04 with KDE3 and there were no problems with this bug. Now, with 8.10 I switched to Gnome and in this environment everything works fine. I'm using IBM Thinkpad T40p.
In my situation, to disable the Num Lock, I have to add one keyboard layout, apply settings, remove it, apply settings again and press Ctrl.

I can confirm that the bug exists on Ubuntu 8.04 LTS with Gnome, on IBM x31 -- it appeared after a dist-upgrade from Feisty.

It is quite annoying for anyone used to using Caps as the Control key. Pressing Caps enables Num Lock both when it is mapped to Control and when not.

I think it's safe to mark this bug as Confirmed as multiple people are having problems in Hardy and Intrepid.

Does anyone have a solution for this? It makes gnome virtually unusable when my laptop is undocked.

Try executing this in a terminal window:

xmodmap -e "keycode 77 = Num_Lock"

Works for me (and fixes the problem instantly, without restarting anything). It affects only current X session, so if it works you will need to add this command to "Startup programs" in System -> Preferences -> Sessions.

I confirm this command helped me to.

The only one small not correct behavior now is the turned LED below the
screen
indicating the numpad is on, even when it is off.

What is more interesting, after I googled I found out that this solution
is known since 2005, so it should be implemented in Kubuntu.

For Kubuntu 9.04 the problem still exists and unfortunately solution proposed in this topic:
xmodmap -e "keycode 77 = Num_Lock"
is not helping anymore.

Since I switched from kde4 to xfce this problem got resolved. But once I launched kde4 again and the problem still exists there.
So under xfce is everything fine,
under kde isn't.
