Description of problem:
When pressing the backspace key within X, the backspace is performed
but then a "q" is printed, again I have seen this occur when using the
tab and delete keys also the function is performed but is then
proceeded by printing the letter "q".
I am using a Logitech Wireless Keyboard and Logitech Optical Mouse.
They are conencted to a Belkin KVM (OmniViewï¿½ ENTERPRISE Series
Dual-Port PS/2 KVM Cable), which goes between one of my XP servers and
my Red Hat 9 server (HP pavilion intel P4 2.8, i686). This problem
only occurs in X on the Linux server, and doesnt occur on the windows
XP machine. Additional I have found a forum where many others are
seeing the same problem but on varying HW and OS release:
Additionally I have noticed that if you press the backspace button and
then quickly start typing, it is not until you stop typing or pause,
that the letter "q" is printed.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Press either the backspace, tab or delete key
2. Problem occurs
Actual Results: After pressing one of the above buttons the letter
"q" is printed, e.g.
# echo hellop
<press backspace, then letter "q" appears>
# echo helloq
Expected Results: The character should be removed and the "q" should
There is a workaround in the fact that you do not press the backspace,
etc keys and use the mouse to highlight and then press space or
something, but it should not be occuring.
I had this happen once with a "K" always appearing on FC2 when
switching on my Belk** KVM switch and getting erratic mouse behavior.
I can't reproduce, though :-(
I had to reboot.
Ok, I don't know if this is related, but I figured out that when using
nano, if I use any of the special keys, like Insert, End or Home, it
replaces them with, for instance, F for End. I don't get anything for
the Backspace, tab, or delete key.
