Public bug reported:
I've a problem with the keyboard of notebook HP Pavilion 15 ab062nl.
the problem is with SHIFT ALT and CTRL buttons of the keyboard.
for example when i use ALT-TAB shortcut, after few seconds, the ALT-TAB menu
disappear as if i release ALT key, but isn't so.
another example is when i navigate on web, when i scroll page with mouse wheel,
sometimes the page start to resize, as if i'm pressing CTRL command while
scroll, or if i'm writing a text, sometimes, borwser launch shortcut, as if i'm
pressing CTRL while i type text, for exaple if i'm typing "b" letter, opens
bookmarks...
another example is while i'm typing text, if i press SHIFT key and start
typing, begins to write uppercase letters and after a while, writes
lowercase like I released shift, but i'm still pressing shift.
for example if i press SHIFT+s, the result is this:
SSSSSSSSSSSSSSsssssssssssssssssssssssssssssssss
some letters are uppercase, but others are lowercase.
i haven't found a solution.
the only way to solve momentarily the problem, is pressing for some seconds the
only SHIFT key, after that, the problems disappears indefinitely, or until the
next restart.
This problem occurs with all ubuntu version (x86 and x86_64), now i'm
using Ubuntu 15.10, but i've also tried ubuntu 15.04, ubuntu 14.04,
ubuntu 12.04, ubuntu 10.04.
furthermore i've this problem also with other GNU/Linux Distributions (i've
tried Fedora, OpenSuse, ArchLinux, Antergos, Debian, SteamOS).
but isn't and hardware problem, because on Windows 8.1 and Windows 10 i haven't
these problems.
i've also tried to plug in an externa USB keyboard, and if i use
external USB keybaord i haven't problems.
i think is a problem of compatibility, with integrated keyboard of this
notebook.
i've tried to monitor these problems using XEV, and the results is that
also if i'm not using notebook, sometimes XEV reads an INPUT of one of
these 3 key (SHIFT, ALT, CTRL), and while i'm pressing one of these 3
key, XEV see also if i release and immedialty after press again the key.
this is an example of the input while i press Left_ALT key for a while
