Touchscreen orientation after fixing screen orientation is wrong

[NeverGiveUpp]

Hi folks, I've just installed Cinnamon 20.2 on an Acer Switch One 10 (https://www.notebookcheck.net/Acer-Aspi ... 888.0.html).

I've got to fix the screen orientation to counterclockwise during installation but the touchpoints were totally off after that.

It's probably due to the touchscreen orientation because it's not rotated counterclockwise like the screen.

I've tried searching on the internet, tried a few stuff but it didn't fix the problem.

I'm not that young anymore but it'll be great to have you guys teach an old fart a tick or two to fix the problem.

Thank you.

Hi folks, it's clockwise, not counterclockwise.

Thank you.

Hi folks, is there a way to make this stick? I tried putting it in 40-libinput.conf and it messes up mint altogether.

xinput set-prop 'pointer:Goodix Capacitive TouchScreen' 'Coordinate Transformation Matrix' 0 1 0 -1 0 1 0 0 1

Thank you.

Think I may have fixed it temporarily by running xinput as a script at startup.

I'm still interested in knowing why this happens and is there a config or setup file that I can edit without running a script at startup.

Welcome to the forum, NeverGiveUpp.

What exactly did you do to "fix" the screen orientation during installation?

[NeverGiveUpp]

Oh, I ran a script with this

xinput set-prop 'pointer:Goodix Capacitive TouchScreen' 'Coordinate Transformation Matrix' 0 1 0 -1 0 1 0 0 1

on startup.

It still doesn't solve the problem of correct orientation if I were to use my screen as a tablet.

Right now, I can use it like a regular touchscreen laptop with the keyboard docked.

Have you checked in BIOS/UEFI to see if there are any settings related to tablet mode or turning on/off the accelerometer?

In the Display app on the Settings tab there is an option to Disable automatic screen rotation. If that is not turned on, is your screen rotating (ie. does it seem like the accelerometer is sending a signal to the operating system)?

As far as the script you are running, I believe you can add the line to the end of ~/.profile which is a hidden file in your home directory. That way it will run automatically after you log in.

Yup I've checked, no settings for tablet mode and accelerometer in BIOS.

I actually want automatic screen rotation but it's the wrong orientation to start with; when I turn the tablet in portrait, the screen rotates to landscape clockwise and when I turn tablet to landscape, it'll rotate to portrait counterclockwise.

Let me check the home directory to see if I can figure that out

I asked the question to make sure the accelerometer was, in fact, working. Someone on a different topic thought theirs was not working, but it turned out the screen had to be moved to almost a flat position before it turned.

Others have run into issues with the screen not aligning properly and I've seen several ways to fix that (but some fixes are specific to a certain laptop model and I'm not sure it would work for others).

Then the issue of the touch not being properly coordinated with the screen is a separate issue which may or may not be connected to the rotation issue. There are different technologies for touch and not all use the same principles which makes addressing the issue a bit more of a challenge.

As a general rule, you would not want to modify a system file (such as the one you mentioned), but would create a new file with your customization such as perhaps a 50-libinput.conf in the user customization directory. It really depends on the specifics of your hardware which would be best. If it is just the one line, then probably just putting it in your .profile file may be all that is needed. If the fix gets more complicated then you would likely want it in a separate file that the system would read.

Hmm, I think I'll need more time to figure out how the hardware works with Linux. Not exactly an engineer but I think it's just some rotation issues because the touch points work fine once xinput set-prop is in place.

You indicated in your first post that the touch points were off after rotating.

If the one line command fixes the issue, just add it to .profile.

The issue is that not all hardware works the same way. That means sometimes the defaults in Linux-based distros work and sometimes they do not.

The touchpoints work after I manually rotated using xinput set-prop.

However, I can only use the tablet docked with the keyboard as a laptop now since it's manually rotated. I'll need to work towards auto rotating it correctly so that I can use the tablet both undocked and docked, like in the case of MS Windows.

That sounds to me like you have fixed the original problem in the title of this topic. It is a manual fix, but it is still a fix. Is that correct?

From this, I understand you to say the fix you have for your original problem (in the title of the topic) is not an acceptable fix for your because when you disconnect the tablet from the keyboard then the screen orientation is not correct in tablet portrait orientation.

When I made the comment earlier about seeing others use several ways of fixing the orientation, I did not mean they found a way to have the orientation automatically change. They found a manual fix solution for their issue.

I just want you to be aware that in your attempts to find a fix for an "automatic" rotation you may be looking for something which does not exist. You may need to run another script to get your screen orientation aligned properly when it is in tablet portrait mode. Or you may find something that works. My searches did not find info about your specific model, but it is possible it's there and I missed it, or a solution that worked for a different model will work for yours.

[NeverGiveUpp]

Yeah, don't think a perfect solution exist now but it'll be great if the community knows about this and work towards that is closer to Windows for a tablet laptop.

As for now, I'm using the tablet docked with the keyboard with both screen and touchscreen rotated clockwise.
