Keyboard sensitivity error

I've just replaced the keyboard and it does not work well in Linux. Problems include:
  1. It can't detect all my keys pressed
  2. Something I did not type appears automatically
  3. With a single press, the character can appear many time (like when the key is pressed and hold).
  4. Directional buttons sometimes generate numbers 2, 4, 6 or 8 (the corresponding number on keypad)

For example, tis sentence istypesd without pessing bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbackspace to correct erors111111111111111111111111111.Theesult i6s funny.(I am glad tt the "repeating" key probl is demostratd. he 11111111111111111111 appared hen I ress 'End button.)

I would think that the keyboard is out of order or don't like my motherboard. But it do work on Windows XP on the same hardware.

Well, did you try it with a stable version -- or even some other distribution?

Good suggestion.

The same problem occurred with ubuntu Version 5.04 for x86.

I really can't use my computer with linux... I am now a happy windows user

New keyboard

What kind of keyboard do you have?
Is it on of those fancy multimedia keyboards?
If it is, that could be the problem.

If it is just a generic keyboard them why not replace it?

It is a PS/2 keyboard.

I don't think it has any fancy feature... It has the stupid Power, Sleep and Wake keys. It also has a Turbo key, which seems to do nothing. Besides these, I don't see anything special.

Replacing it is an option (I can affort it). But I don't think the shop will exchange or refund when the new keyboard also has the problem. There is no such problem on Window.

It is bascially impossible to login any website, because you don't know what you type in the password...(Don't complain my spelling)

Some new finding:
1. The keyboard works MUCH better on the virtual consoles than XWindow, but still far from perfect.
2. Pressing the arrow keys and the 6 keys above the arrow will sometimes cause the following message or somthing similar:
atkbd.c: Unknown key released (translated set 2, code 0xe0 on isa0060/serio0).
atkbd.c: Use 'setkeycodes e060 <keycode>' to make it known.
Any idea?

Eventually, after buying a new keyboard, the problem resolved.

But I don't know why the problem only occur in Linux, but not windows...

Xorg -configure should fix your problem on any distro

If you are having a problem with your keyboard keys repeating or seeming to stick here is how to fix it. This should work with almost any ubuntu kubuntu or other distros with gui's you will probably only see this problem in a gui desktop. Don't try to fix it with keyboard settings it won't help you. You probably added a new keyboard to your system or you selected a wrong keyboard option when you installed.

If you are using ubuntu or kubuntu or the sort logout then select session type terminal write the following command down before you do so that you will know what to do next. Or just open a terminal accessories-> terminal

sudo Xorg -configure

type the above command at the command line.
It will probably give you the following info

Fatal server error:
Server is already active for display 0
If this server is no longer running, remove /tmp/.X0-lock
and start again.

So do what is says and remove that file with the following command

sudo rm /tmp/.X0-lock
Then type the above command again

sudo Xorg -configure


sudo reboot

Everything should work perfectly now.

The problem was caused by a bad xorg configuration. the Xorg -configure command automatically configures your keyboard for you.
