[Monitors] Trouble with screen auto rotation (as in, its not working)

[pigeon]

Hi, I am trying to get the auto-rotation working on my Lenovo N23, but cant get it to work.

If I run a `systemctl status iio-sensor-proxy`I get the following:

iio-sensor-proxy.service - IIO Sensor Proxy service
Loaded: loaded (/lib/systemd/system/iio-sensor-proxy.service; static)

Oct 17 00:02:26 pigeon-Lenovo-N23 systemd[1]: Started IIO Sensor Proxy service.
lines 1-12/12 (END)

Running `monitor-sensor` gets me:

$ monitor-sensor
Waiting for iio-sensor-proxy to appear
+++ iio-sensor-proxy appeared
=== Has accelerometer (orientation: normal)
=== No ambient light sensor
=== No proximity sensor

And, when I rotate the laptop it prints as expected:

Accelerometer orientation changed: right-up
Accelerometer orientation changed: bottom-up
Accelerometer orientation changed: left-up
Accelerometer orientation changed: normal

When I put `cat /proc/bus/input/devices` this is the printout:

I am completely stuck on how to get this working, and throw myself on your mercy!

Switch from Xorg to Wayland and see if it works --it probably will
You will need to install a package to add it as an option on your login screen:

sudo apt install plasma-workspace-wayland

However.....You won't have an on-screen keyboard. Kubuntu is missing maliit keyboard still, for some reason? I keep forgetting that.
KDE Neon has it.

The other option is to find and modify scripts that handle this in Xorg, and use Onboard as a keyboard.
I did this when I had such a laptop. I can;t find my notes, but they were sort of hardware-specific, even though it was a lenovo laptop.
I chucked them when I switched to Wayland
Being a 'vintage' Chromebook, at least hardware-wise, might make it a little more "interesting"


Two year old post mentioning a 6 year old script:
https://www.kubuntuforums.net/forum/...230#post629230
As far as I recall at the time, that was the ahem *easy*, but reliable method in xorg. For me rotation was molasses slow, and 90 degree resolution was always off. I never did get it tweaked to look nice and be readable.

Ok, installed, but could do with some help on adding it as an option to the login screen (could also do with help on changing to having to put in a password at login, and I ticked the wrong box and now it boots straight into the desktop)

Fine with no keyboard, just really want it to view PDF files in portrait.

Login settings: System Settings Search 'login'
In the SDDM settings, select 'Behavior' and change the autologin settings from there


At the login screen, look at the bottom left corner , you will now see the option. This is also where you would select different desktop environments/sessions, if you install any.

Thank you so much for walking me through that.

But, still getting no rotation on the screen, so strange as the accelerometer has no issue with printing out what the orientation should be

$ monitor-sensor
Waiting for iio-sensor-proxy to appear
+++ iio-sensor-proxy appeared
=== Has accelerometer (orientation: normal)
=== No ambient light sensor
=== No proximity sensor

Accelerometer orientation changed: right-up
Accelerometer orientation changed: bottom-up
Accelerometer orientation changed: left-up
Accelerometer orientation changed: normal

Try checking that the setting for 'only rotate in Tablet mode' in System Settings monitor section is un-checked. I think I had to do this on my laptop. I forgot this setting.
I don't have that Lenovo Flex any more, I sold it so I could get a Duet 5 Chromebook - Arm based, auto-Rotation does work, but I configured the OS build wrong for this Arm64 device, so the screen is 180 degrees off when not connected to the keyboard.
And I have forgotten exactly where to go to adjust this lol.

Hopefully being an SoC type of system as opposed to a 'normal laptop isn't an issue here, as these can have unique hardware oddities and can sometimes NOT be plug-n-play. A and B may both work, but might not be connected in the right way.

Thank you so much, this was the problem, went back into Xorg just to sanity check, as I was sure I had looked for that option, and sure enough, it doesn't show up Xorg, just Wayland!

Now I just need to work out how to make a macro that presses the 2 function keys to turn off Keyboard and trackpad for when I have it folded up like a tablet as it doesn't seem to go into a "tablet mode" when folded up.
