Poll: Caps Lock delay
Do you have the Caps Lock issue, that is when you fast intermittent press Caps Lock and another key. When Caps Lock isn't released fast enough you don't get a nice sequence of upper case and lower case.
Example you should get: Quote:

read this thread first to get an idea what is meant. @OP: It might be a good idea to link to the above thread in your initial post so that the whole discussion does not have to be repeated. |
This whole caps lock thing has nothing to do with the keyboard. It is PEBCAK.

There is no problem if you use the right key for the right job! Use the 'Shift' key! |
I agree that it's better to use shift for one letter, but the issue is that there should not be such a long delay between when you release caps lock and press fast the next key that you get upper case instead of lower case. Doesn't really matter if you type a whole line in upper case or one letter. It should just work.

I think that complaining that your computer doesn't support something that was it was never intended to do in the first place is a waste of time! That said, I wonder if it's more likely to be caused by hardware than by the OS, since only 1 person out of 9 has had the experience.

Definitely no issue here, no matter how fast I try.

Caps Lock
I turn the blasted thing off & make it an additional backspace in Keyboard-Layouts-Options in Ubuntu

I can duplicate the effect, but I believe it is mechanical.
What I've noticed is that when I get the unexpected upper-case characters in the sequence, an examination of their Xevents show that the KeyPress event for that character comes between the caps_lock's KeyPress and KeyRelease events. Normal character input is actioned on the keypress, The caps_locks effect appears to turn on on it's KeyPress event, but only turns off on its KeyRelease. While the caps_lock key remains depressed you always get a upper-case letter no matter what state it was in before the keypress or will be in after the keyRelease. This may be the cause of the perceived latency as the key release event's timing will depend on the strength of the mechanical spring in the keyboard and how much travel is necessary to break the contact, not to mention you're probably slower at removing your finger than you were at applying it. For exceptionally fast typists, this may be long enough to cover the following KeyPress. Well, that's my theory for what it's worth. Changing the caps_lock off to action on keyPress rather than KeyRelease would probably fix this, but I don't know how one would go about doing that. I can't type fast enough to see this problem in normal use, and I never use caps-lock anyway (well, never on purpose ;) ) |
Mine behaves as though there's no "N-key rollover" for the caps lock followed by "A".

Hi,
For mechanical keyboards I will throw in the de-bounce circuitry that will filter errant contact bounce. Capacitive keyboards really do not have the contact bounce issue. Most modern keyboards in use today do not use a mechanical switch contact, cheaper to manufacture capacitive. Hall-effect at one time was the best choice for keyboards but costly. Some snap contact(membrane) keyboards are used but these tend to be limited to special applications. Keyboard technology wiki is a good reference to understand the technologies. Personal choice is limited to available designs unless you wish to spend the money for a particular keyboard type. I still have some original IBM mechanical keyboards, those babies are rock solid with a great key feel or feedback. Heavy but reliable! When IBM changed the contact to a hall-effect type they had too re-design to get the mechanical feel back so people had the old feel. Now most PC keyboards are capacitive. No real tactical feel. |
hmmm......
i see it doesn't bring too much problem since i rarely use caps lock button |
AaAaAaAaAaAaAaAaAaAaAaAaAaAaAaAaAaAaAaAaAaAaAaAaAaAaAaAaAa
Is there any issue at all? |

No problem here on my EeePC 901. |
*points at response to other thread*
as i said on the other thread (in so many words), there's a reason it's called caps LOCK using the caps lock key as a shift key is kinda like trying to use the parking break to stop the car.[COLOR="Silver"] why do so many people insist on using things in ways that they aren't intended and complain that they are broken when it doesn't work that way? |
PEBKAC is PEBKAC does.
I just wish my water bottle holder would work. (I don't drink coffee, it makes you short) ;) |
