keyboard problem on linux

[1.] i've a problem with keyboard of my notebook HP Pavilion 15 ab062nl; CTRL SHIFT and ALT buttons not works as they should. in particular, it is as if these keys are pressed and released alone. isn't an hardware problem, because on windows 10 and windows 8.1 i haven't these problems, is only a linux problem (all distro).

[2.] the bug is always active, every time i start a linux Distro (also from live, and also without DE/WM) i've this problem with keyboard, the only way to fix temporarily the bug, is pressing the only Left SHIFT key for some seconds, then all problems disappear indefinitely, and in any case, if i shutdown or if i reboot the PC, the problem recurs.

Hmm, this is weird. Do you observe the same issue in text console (not in X)? It would be nice to see events as emitted by the kernel - you can use evtest utility for that.

Is sounds like some accessibility feature, is there anything in BIOS to that effect?

Thanks.

Hi, Dmitry
i've the same problem on console without X.
this is an output of evtest on console:
http://pastebin.com/4aWYYhwN
(as you can see, after a while i'm pressing Left_Alt (from line 434 of pastebin) or Left_Ctrl (from line 605 of pastebin) or Left_Shift (from line 786 of pastebin), these keys are released and then pressed again. but when i press only left_shift for some seconds, the issue don't occurs.)

i haven't found nothing on BIOS settings, the only options relative to keyboard is:

Action Keys Mode:
[Enabled]: Requires pressing only F1 throug F12 to activate action keys [Disabled]: Requires pressing FN Key + F1 throug F12 to activate action keys

but the problem occurs in both modes

i've installed the new kernel 4.5 RC1, but i've the same problem. i've also tried start ubuntu with upstart, same problem. i don't know why i've this strange problem.

i've also tried GhostBSD on live (i don't know if this information can be useful), the problems occurs also on BSD but seem that is less severe than on Linux, because on BSD seems that the problem occurs only one time every boot, then disappears without do nothing (don't need to press MAIUSC key for some seconds).

I hope that this bug can be solved.

the problem occurs also when i logout to login manager.

for example if in this moment i haven't the problem (because i've pressed for some seconds MAIUSC key) and i logout, the problem occurs again infact sometimes, when i logout, and then i try to login again, the login manager doesn't accpet the password because the passowrd contains uppercase letters, but sometimes the OS don't take maiusc key (I hope I explained well)

i hope that this information can be useful.

Hmm, this is weird. Do you observe the same issue in text console (not
in X)? It would be nice to see events as emitted by the kernel - you
can
use evtest utility for that.

Is sounds like some accessibility feature, is there anything in BIOS to
that effect?

Thanks.

when i'm into grub EDIT Selection (pressing E on grub interface) and into GRUB CommandLine, i haven't these problems.

furthermore, i've tried to add to /etd/default/grub

i8042.nomux=1 i8042.reset i8042.direct

and the problem is almost solved, now when i start PC i haven't problems, the problems occurs only 1 time when i press block num key or block maiusc key, but then the problem disappear alone, without pressing maiusc key for 2 seconds.

i hope that these information can be useful, and i hope that you will answer me.

the problem occurs also when i logout to login manager.

for example if in this moment i haven't the problem (because i've pressed for some seconds MAIUSC key) and i logout, the problem occurs
again infact sometimes, when i logout, and then i try to login again,
the login manager doesn't accpet the password because the passowrd contains uppercase letters, but sometimes the OS don't take maiusc key
(I hope I explained well)

i've installed the new kernel 4.5 RC1, but i've the same problem. i've also tried start ubuntu with upstart, same problem. i don't know why i've this strange problem.

i've also tried GhostBSD on live (i don't know if this information can
be useful), the problems occurs also on BSD but seem that is less severe
than on Linux, because on BSD seems that the problem occurs only one
time every boot, then disappears without do nothing (don't need to press
MAIUSC key for some seconds).

I hope that this bug can be solved.

Hi, Dmitry
i've the same problem on console without X.
this is an output of evtest on console:
http://pastebin.com/4aWYYhwN
(as you can see, after a while i'm pressing Left_Alt (from line 434 of
pastebin) or Left_Ctrl (from line 605 of pastebin) or Left_Shift (from
line 786 of pastebin), these keys are released and then pressed again.
but when i press only left_shift for some seconds, the issue don't occurs.)

i haven't found nothing on BIOS settings, the only options relative to
keyboard is:

Action Keys Mode:
[Enabled]: Requires pressing only F1 throug F12 to activate action keys
[Disabled]: Requires pressing FN Key + F1 throug F12 to activate action
keys

but the problem occurs in both modes

i've tried to add this parameter to kernel

i8042.direct

and in this way the problem disappears completely, but the caps lock LED won't turn on.

so i think that there is a problem with the keyboard controller
