My husband has converted the entire household to Ubuntu, so far things are going fine, except for this small issue, I have a ps/2 Genius keyboard model, KB-06X attached to a desktop computer and on rare occasions when I am typing in any application, Word processor, text editor or forms and I activate capslock what I get are lower case characters, when I deactivate capslock (green light off) I got upper case characters, I noticed this as far back as 8.04 and as recent as 10.04, I have not noticed it yet on 10.1, even if 10.1 fixes the problem I am still curious as to why this happen on the others.

Is it just cheap faulty keyboard or is this a known problem?

Have you tried taking the caps lock key off and removing any cruft/food/etc? You could also try using the keyboard on Windows. –  user6658 Jan 22 '11 at 0:58
When this occurred the keyboard was new, I have a habit of keeping my input devices in good condition, The only Windows we have now are the ones that let light and air into the house :) –  dblang Jan 22 '11 at 2:35

It covers a selection of different solutions so hopefully one will work

Hope this helps.

I had the same problem, except my keyboard is a Microsoft (forgive me) Digital Media Pro (plugged into an HP Pavilion dv6-3120us Entertainment Notebook), and it is a usb keyboard. I don't think I had the problem originally when I switched from Windows (forgive me) to Ubuntu 12.04 LTS. Then all of a sudden, I noticed it was reversed. And I am not certain that is stays reversed. Anyhow, my solution was simply to unplug the keyboard, then plug it back in. For PS/2, you may need to use a ps/2 to USB adapter, as it has been my experience that ps2 devices cannot be unplugged and replugged without rebooting.

I realize the above post does not answer the question 'Is it a faulty keyboard or a known problem'. Hopefully though it sheds more light on the subject. Also, I've noticed that after the screen saver is invoked, the sense of the caps lock key is reversed, so it is flipping back and forth from reversed to normal. –  Kevin Field Jan 19 at 2:28
