** Description changed:
I noticed strange behavior from my Ubuntu system. While left idle, the
screensaver would shut off with no interaction with the machine. While
using the machine, webpages would zoom in or out when trying to scroll,
and command windows would open while typing.
Using xev, I found that these events corresponded with ALt_L, Control_L
and Shift_R events, even though those buttons were not being pressed.
I'm attaching a xev log, searching for _L will show the events.
((Shift_R events are, for some reason, much rarer and do not occur in
the particular log I'm adding.) In many (but not all) incidents, the
KeyRelease event occurs without a preceding KeyPress event. This
problem starts a variable period of time after booting the machine;
generally within 4 hours. Once it starts, it persists until a reboot.
Disabling the trackpad with xinput will stop the problem for several
hours, but eventually something re-enables the trackpad and the problem
reappears.
+
+ WORKAROUND: Use kernel parameter:
+ i8042.dumbkbd
Running memtest on the box generates an error when one specific core
runs one specific test, but I cannot rule out that being related to
memtest's problems with UEFI systems. (See
passmark.com/forum/showthread.php?5638 for info on my memtest results
and the UEFI issues.) I returned the machine to HP for service. They
replaced the keyboard, trackpad and memory. This did not resolve the
problem.
I've recreated the problem in UbuntuMate, Ubuntu, and Debian, on both
3.x and 4.x kernels. I cannot reliably reproduce the issue on the
Windows partition on the same box; I think I might have seen it once or
twice while working on the machine, but can't rule out accidental
keypresses by me at those times. Leaving a keylogger running for over
24 hours on the Windows partition did not show any unexpected keyboard
events.
