(Note: I'm a bit of a Linux Newbie)
I've tested this out on both GNOME and KDE and I get the same problem on each. My keyboard seems to "stick" once and a while. Example:

The quick broown fox jumped over the lazy dog. The quuicck broown ffoxx jummpped over the lazyy dog. The quick browwn foxx jumpped over the lazy dog!!.

Please note I do know how to type (Typing speed off 80+WPM). The real strange thing is, everything works fine if I switch to a terminal (TTY1 etc.) but if I use the GUI I get the above typing problems. (It also works fine in Windows).

Also I am using a Toshiba Laptop, and the keyboard itself iis fine.

Thanks.

I have exactly tthe same problem. Im usinng Mandrake 9.1 onn aa toshiba satellitee 2455-s305. Can sommebody help us?.

P.S. I have problems turning off my computer too. Thee computer dosn t turn of. At thhee end, I only gett a still turned on computer and a message saying "shutting off".

P.S.S. Sorry about my bad english aand my typping errrors, i hope fix it soon.

under Mandrake 9.1 and Toshiba sattelite 1400-503 this problem can be solved by xbounce program.
it's easy to find and dowload rpm with xbounce.

One thing I've found tricky (probably, because I'm so lame linux user) is that I cannot find way to start xbounce automatically. I've tried puttin' it in .xinitrc in /home/user , in /usr/bin/X11 and in /root locations but it doesn't seem to work from there.
Only way it works i to run it manually (from console under X). Then all keyboard problems (doubled keys and so on) disapear What a relief ! This bug was VERY IRRITATING!

Can anyone tell how to start xbounce automatically ??
