Summary: Keyboard shift state not registered under fast typing or autorepeat

If someone can help point me where to look at the code, I've already looked into ./drivers/char/keyboard.c but didn't see anything obvious. More specific help would be appreciated.

Kernel doesn't register shift state when typing quickly. Example, 'ls *' shows up as 'ls 8' when typed fast. Also, holding '-' key down, once it's repeating, shift key makes no difference. Interesting info:
keyboard delay settings of 500/30 allowed me to press shift key soon (8-10 chars) into the repeat and have it change to '_', while delay settings of 250/30 shortened that to the delay between the first and second character.

Holding shift key down first, allows the repeating '_' character to change to '-', but thereafter stays '-' regardless of shift state.

NB: This is not necessarily related to XFree86 at all. I logged in on console, behaviour is mostly identical with one caveat. When starting with '-', pressing the shift key before the repeating starts shows the next 2 '-' but stops the repeat. Pressing shift after it's started repeating does nothing. Otherwise, behaviour is identical

Kernel version: Linux version 2.6.0-test4 (gcc version 3.2.2 20030222 (RedHat Linux 3.2.2-5)
Also on kernel versions 2.4.20 (RedHat 9)) and 2.4.21 stock and 2.4.21 patched with acpi/laptop patches

No OOPS

No example scripts

Special note, this is a Compaq Presario X1000 Laptop.

Summary: Keyboard shift state not registered under fast typing or autorepeat
If someone can help point me where to look at the code, I've already looked into ./drivers/char/keyboard.c but didn't see anything obvious. More specific help would be appreciated.

You must look at input/input.c at occurrences of repeat_key. (And afterwards at char/keyboard.c at kbd_event, kbd_keycode.)

You'll see that the current 2.6 code ignores a lot of what the keyboard is telling us and synthesizes its own events.

What happens in your autorepeat case:
- Press a key, repeat_key is set to its keycode.
If you keep it pressed then the keyboard repeats are ignored, but the kernel generates its own repeats using a timer.
- Press Shift, repeat_key is set to its keycode.
Now the timer repeat generates repeats of the Shift-down event, but that does not generate keyboard input.

But in your autorepeat case the kernel does precisely what the keyboard also would have done: repeat the last key that was pressed. Also the hardware keyboard does not send anything after Press A, Press Shift, Release Shift.

Incidentally, both add_keyboard_randomness() and add_mouse_randomness() are called - we invent more randomness than one might have thought at first.

Kernel doesn't register shift state when typing quickly. Example, 'ls *' shows up as 'ls 8' when typed fast. Also, holding '-' key down, once it's repeating, shift key makes no difference.

So, the first part of what you say, when true, would be a bug. But a bug difficult to distinguish from a finger coordination error. The second part is correct behaviour.

Thanks for the pointers. I was about to argue about what proper behavior is, between what I see on my desktop 2.4.20 (RH9) and laptop 2.6.0, but then I saw what WinXP does, and some things clicked irrelevant. Anyway, thanks for the info...

I don't believe any of this is coordination errors. Shown below is a log of some debug I added to my kernel (2.6.0-test4). I put debug stmt at the very top of input.c, before any possible return; and also in all the relevant if(...){ ...; return; } blocks in keyboard.c, as well as one or two general info statements in keyboard.c (if you need to see where, I'll post my patch, but I doubt it's necessary)

Here's the log, I did 'tail -f messages' and then typed 'ls <shift>8' in the window, so it's obvious at what point I'm typing:

Please note the bad version doesn't receive any notice of the shift-down event, but gets the shift-up event, proving that I really did press it;) The good version gets shift-down and shift-up properly.

My question: Is there anywhere else I can look, perhaps the code which calls input.c::input_event()? Or is this potentially a hardware problem (i.e. should I return my laptop, because this is too d*mn annoying)?

Thanks for the help
Regards,
Carl

typing slower, at least making sure the space <shift> are separated.

Kernel doesn't register shift state when typing quickly. Example, 'ls *' shows up as 'ls 8' when typed fast.
Typing quickly:

You can try to decide by running a 2.4 kernel on this laptop. If also 2.4 fails it may be hardware. If not, we must fix 2.6.

It was the same behavior on 2.4.20, 2.4.21, 2.6.0-test3/4, and also XP. It's a hardware problem, I'm sending the thing in for repair.

Sorry for the false alarm, but it helped to narrow down what was happening, so thanks for the pointers.
