I have a keyboard problem that I figure *must* be a keyboard hardware
problem, but it doesn't really look like it. When I bring up either
Ubuntu 12.04 (installed) or Fedora 17 (from Live CD) and use either the
"Terminal" program or xterm, I can type some small number of characters
(~10-20) without a problem. As I type more, though, other characters
start getting inserted. This will typically start with a newline, but
then I get short strings, starting with an ESC character, then I'll get
multiple copies of things I've typed many lines before. The extraneous
text may be inserted while I am typing, but there may be a short (~0.5
sec) delay before it appears. The ESC strings will be things like cursor
up or down. It quickly becomes possible to do much of anything.
I see the same problems when entering text on other programs, as well,
such as Thunderbird or Firefox. Note that I don't see any keyboard
problems when using PuTTY or any other program on (yech) Windows.
This probably began when I switched my installation from Fedora 16 to
Ubuntu 12.04 or shortly thereafter (clean install of *everything*,
including Windows).
My system is an HP Envy 17" 3D (2090nr).
I can't believe this is software because other people would see it; I
think pretty much anyone would be ready to pitch their system off a
cliff in frustration. Yet, the problem only happens when running Linux,
appears to have started with a kernel upgrade (as part of the Ubuntu
install), and there isn't any hardware buffer I know that would keep
things I typed hundreds of characters before.
I'm a little desperate here--I bought the system for kernel development
but I work on embedded systems without keyboards; any suggestions, or
even just confirmation that other people see the same thing, appreciated!
