Description Greg Harvey 2020-05-10 17:50:56 UTC
Description of problem:

I have a brand new Lenovo ThinkPad X390 Yoga. I installed Fedora 32 and it all seemed fine until I first tried tablet mode. The screen rotation is basically broken. Note, yes, I did check rotation wasn't locked in GNOME!

There's some more info here:
https://forums.fedoraforum.org/showthread.php?323834-Accelerometer-not-working-software-problem-or-broken-hardware

There's very little output, even when using 'monitor-sensor' in a terminal to see what's going on. It's like the rotation events are simply not detected at all most of the time. Then suddenly it picks up an event, rotates and the screen is stuck like that. You have to keep tilting and eventually it notices and rotates back the way it's supposed to be, but all the while you're doing this there's no output from monitor-sensor, until the actual rotate event - then everything appears normal.

I had bought the machine because it is Ubuntu certified for 18.04 LTS, so I decided to try a live USB of the latest Ubuntu (20.04 TLS) and, curiously, it has the exact same problem as Fedora 32. I then tried a live USB of Ubuntu 18.04 LTS aaaaand... the laptop functions perfectly! Screen rotation in tablet mode or otherwise is snappy and perfect.

So it seems *something* broke, either between kernel versions 4.x and 5.x or in the iio-sensor-proxy package itself?

I'm happy to provide more info for debugging, but I have no idea where to start so I'd need some guidance from the maintainers as to what logs/output is useful.

In any case, this is definitely a recent issue as older versions of Ubuntu work, and I haven't tried but I suspect it might be fine with Fedora 29 (kernel 4.18) as well?

Description  : IIO accelerometer sensor to input device proxy.



How reproducible:

It happens every time with the right hardware and Fedora 32.


Steps to Reproduce:
1. Buy or borrow a ThinkPad X390 Yoga
2. Install standard 64 bit Fedora 32 Desktop on it
3. Try to tilt the computer and note the screen doesn't rotate!

Actual results:

Rotation mostly doesn't happen, but does sometimes randomly work for one or two rotations, then it stops working again.


Expected results:

Screen rotates smoothly and rapidly, just as it does with Ubuntu 18.04 LTS.


Additional info:

Upstream repo seems to be here - I'll raise an issue there too:

Comment 1 Greg Harvey 2020-05-10 23:11:01 UTC
The system works with a Fedora 31 live USB:

Installed Packages
Name         : iio-sensor-proxy
Version      : 2.8
Release      : 1.fc31
Architecture : x86_64
Size         : 131 k
Source       : iio-sensor-proxy-2.8-1.fc31.src.rpm

Will double check with a Fedora 32 live USB tomorrow to make sure it definitely doesn't work with a "clean" install. Assuming that's the case, I'll reinstall the system with Fedora 31 and see what happens when I upgrade iio-sensor-proxy, as I see there is a 3.0 release in the Fedora 31 updates repo. If 2.8 -> 3.0 breaks things in Fedora 31, we're pretty close to a smoking gun. I'll let you know.

Alright, so this is really weird. Tried a live USB of Fedora 32 and it was fine, checked the package info and there's been no update, rebooted the machine using the installed Fedora 32 on the disk and it now works fine! So whatever it is, it seems to manifest after the machine has been on for a while. I'll have to do more testing to reproduce consistently. :-(

Comment 3 D. Hugh Redelmeier 2020-12-14 04:03:57 UTC
Screen rotation no longer works on Acer Spin 1.  I think that it stopped when I upgraded to Fedora 33.
This computer is using Gnome 3.38.2 (version of gnome-shell)

I suspect that it is this bug https://gitlab.gnome.org/GNOME/gnome-shell/-/issues/3255

Comment 4 D. Hugh Redelmeier 2021-01-17 19:40:17 UTC
Re comment 3:
It turns out that screen rotation works, but only when you fold the keyboard behind the screen ("tablet mode").
This ia a new behaviour.  Although it makes sense, it isn't what I'd like.

Comment 5 Fedora Program Management 2021-04-29 16:53:33 UTC
This message is a reminder that Fedora 32 is nearing its end of life.
Fedora will stop maintaining and issuing updates for Fedora 32 on 2021-05-25.
It is Fedora's policy to close all bug reports from releases that are no longer
maintained. At that time this bug will be closed as EOL if it remains open with a
Fedora 'version' of '32'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version' 
to a later Fedora version.

Thank you for reporting this issue and we are sorry that we were not 
able to fix it before Fedora 32 is end of life. If you would still like 
to see this bug fixed and are able to reproduce it against a later version 
of Fedora, you are encouraged  change the 'version' to a later Fedora 
version prior this bug is closed as described in the policy above.

Although we aim to fix as many bugs as possible during every release's 
lifetime, sometimes those efforts are overtaken by events. Often a 
more recent Fedora release includes newer upstream software that fixes 
bugs or makes them obsolete.

Comment 6 Ben Cotton 2021-05-25 17:20:29 UTC
Fedora 32 changed to end-of-life (EOL) status on 2021-05-25. Fedora 32 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.

If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version. If you
are unable to reopen this bug, please file a new report against the
current release. If you experience problems, please add a comment to this
bug.

Thank you for reporting this bug and we are sorry it could not be fixed.
