Greetings.
It seems my assumptions were misplaced. It seems the ACPI event
is connected to the accelerometer perhaps, since it fired also
when tilting the laptop rather than folding the screen part. That
includes tilting sideways. The accelerometer works fine anyway, so
i still dont know what those alerts were about.
Greetings.
On a friend's Lenovo Thinkpad X1 Yoga that i sometimes get to
manage i noticed the following message in the output of
`journalctl -f`
thinkpad_acpi: unknown possible thermal alarm or keyboard
event received
thinkpad_acpi: unhandled HKEY event 0x60f0
thinkpad_acpi: please report the conditions when this event
happened to ibm-acpi-devel@xxxxxxxxxxxxxxxxxxxxx
This message appeared as i was folding the screen backwards.
This is a "convertible" laptop, i.e. you can fold the screen
past 180 degrees. Almost 360 degrees in fact. This enables it to
be used as a tablet also. So on Windows when you fold it past a
certain point (about 180 deg), then the input devices on the
"top" side get turned off: keyboard, trackpoint, trackpad and
also keyboard backlight. On Linux the keyboard and keyboard
backlight do get turned off at the same point (as theyre
supposed to). It feels as if the thing blocking keyboard input
is mechanical rather than software/firmware, since i physically
cant press the keys down any more. Currently i made a script to
turn off the trackpoint and trackpad. But as a trigger i can
only use the final state of reaching the 360 deg fold as a
trigger (which shows up in acpi_listen).
This message gets launched 2 times (so 6 lines of text) when
folding past the 180 deg point and again 2 times when folding
back to normal position (90 deg e.g.). But this message
only gets launched when the movement is slow enough - when i do
it quickly it doesnt show up at all! I havent booted Windows to
check out how this nuance behaves there.
Also is there any way i can harvest this event to launch my own
scripts?
If there's any other help i can provide (logs, tests,
observations) let me know. Im a novice Linux user, so i dont
know what im doing, but i can make a few scripts and i managed
to stumble upon the 2 commands i mentioned in this post. Ill
continue to have access to this pc for another 3 days and after
that access will be (certain but) sporadic (unless i learn how
to get to their home network with ssh (i did read how to do it
if i had my own server, which i dont)).
All the best
