Changing the typematic delay to 1000 did not fully take care of the problem either. The symptoms happen less often, but still occur regularly. For example, when I was working on a lab example from my RHA material I needed to su to root for something and it took 8 tries just to su to root!! On 4 of the first 7 tries, it registered multiple "enters" for one keypress of the enter button...so I obviously got a failed attempt since it was searching for a blank password. On the other 3 attempts it registered multiple keys while typing in the password. It was an extreme pain in the rear.
I am thinking that it cant just be a bios issue because my typematic rate is way slower than what happens when its being weird. With these error symptoms I might get 15 "t" characters when trying to begin the word "the"...but they appear instantly...if I intentionally create 15 "t" characters it takes a good amount of time because I have the typematic delay all the way up and I also have the typematic rate pretty slow.
I would have tried a new keyboard by now but I have the same keyboards for my rigs, so I'll have to get one elsewhere.
