Hello,

after a nightmare with GNOME (I'm really a GNOME fan - but it's not for tablets....) I finally came to KDE, and that's really nice. It's vast configurability helps a lot.
Unluckily, the auto-rotate feature does not work. https://bugs.kde.org/show_bug.cgi?id=384066 - I'm still with plasma 5.12 at kubuntu 18, Xorg.

I could be happy with manual rotation (often the automatism causes more trouble than pleasure...), but when I rotate the screen by 90°, only the actual readout and the mouse reaction rotates - not the touch screen response. Meaning: When I move my finger vertically, the mouse pointer will move horizontally, ande vice versa.

Does someone have a hint for a fix or a workaround?
NB: The wayland version does only rotate by 180°, not by 90°.

Cheers,
Wolf

This has been solved quite some time ago, I suggest you get a newer Plasma version, yours is really old now.

Thank you for this hint. I found https://community.kde.org/Kubuntu/PPAs#Kubuntu_Updates, but in the end I did not get any further than plasma 5.12.9, the problems persist. Are there any possibilities to get more recent updates - or could I only go to ubuntu 19 ?

Cheers,
Wolf

Why not give Kubuntu 19.10 a try? There is really no reason to keep using an LTS version, especially not on a tablet. LTS is meant for businesses who have to manage multiple installations which is easier with an LTS installation, but there is no reason for a private user to do so.

FWIW: Plasma Mobile would be a good choice for a tablet as it is optimized for this kind of devices.

Allright, let's try that. Former experience with a non-LTS on my desktop was awful, but that may be much better on that tablet.
Edit few hours later: No improvement at all. Neither with Xorg, nor with wayland, ):

That would mean a fresh install of Neon - https://www.plasma-mobile.org/get/ - correct? - Looks interesting, but first let's see how much happy I can get with ubuntu 19.

Thanks a lot,
Wolf

I tried plasma-mobile. Well. At the moment it's not for real use. Last update 2019-02-18 is not so promising...
I switched from ubuntu to manjaro, but more recent KDE version do not cure the core problems.

Sad. It's quite small bits missing to really have fun with KDE on a tablet, but they are missing...

• emulation of right-click
• screen rotation (dunno care whether automatically or manual
• easy scaleable sliders would be nice, the defaults are way too narrow

In the meanwhile, I had certain success with manjaro Linux KDE. I summarized steps and struggles here:

Hi,
I use plasma on a Lenovo Thinkpad l380 Yoga.

Automatic screen rotation (WITH Stylus!) works fine with

- screenrotator : https://github.com/GuLinux/ScreenRotator

- kded rotation: https://github.com/dos1/kded_rotation

Both of them rely on iio_sensor_proxy, so you will have to have those installed.

Screenrotator is faster, so I use that, but both work.

What I would like to have: The L380 Yoga (and most other convertibles, too) have a 16:9 screen ratio. So I place my kde panel on the left in landscape mode. I would very much like to place it on the top in portrait mode - which is, of course, easily done by hand after rotation. But this should happen automatically.

In which config-file is the place of the panel located? I could then integrate that into one of the screen-rotation programs.

Regards, Andreas

Hi,

I am kind of confused. Everywhere I hear that tablet rotiation works out of the box. I am sitting here with a new (well used new to me) Yoga 370 and searching for 2 hours now not finding a real solution.

I have installed Kubuntu 20.04, Plasma 5.18.4, KDE 5.68.0, Qt 5.12.8 Kernel 5.4.0-29-generic and feel stupid.

What am I missing?

I will try this now but that's not out of the box, is it.

- screenrotator : https://github.com/GuLinux/ScreenRotator

- kded rotation: https://github.com/dos1/kded_rotation

Hi,

another question for manual rotation.

Using xrandr -o inverted

works out of the box. xsetwacom somehow is called inverting the the touchscreen as well.

Unfortunately turning the screen left is more complicated.

xrandr -o left turns the screen and turns xsetwacom to cw which is wrong, so I use now:

Code: Select all

xrandr -o left

#trackpoint 14
xinput set-prop 14 "Coordinate Transformation Matrix"  0 -1 0 1 0 0 0 0 1
#touchscreen sleep needed otherwise the Rotian stays cw
sleep 1
xsetwacom set "Wacom Pen and multitouch sensor Finger touch" "Rotate" "ccw"
xsetwacom set "Wacom Pen and multitouch sensor Pen stylus" "Rotate" "ccw"
xsetwacom set "Wacom Pen and multitouch sensor Pen eraser" "Rotate" "ccw"


So somehow xrandr calls xsetwacom but where? (So I can fix it there)

Regards

I have never heard that xrandr calls xsetwacom. I used to have some scripts for screen rotation (before I got my thinkpad yoga), I always called xsetwacom (or rather the xinput equivalent) after the xrandr call.

I also have never heard that this works "out of the box". If so, it is a convenience by the distro used, but it is not in kde itself.

I have my knowledge about screen rotation from the arch wiki:

https://wiki.archlinux.org/index.php/Ta ... c_rotation

The arch wiki is always worth reading, even if you do not use arch.

Hi,

I have never heard that xrandr calls xsetwacom. I used to have some scripts for screen rotation (before I got my thinkpad yoga), I always called xsetwacom (or rather the xinput equivalent) after the xrandr call.

me neither, this behavior did cost me some time. As on my yoga xrandr appearently works semiautomatic. I don't know if it "calls xsetwacom" I just noticed the output of xsetwacom --get changes after calling xrandr and I have no idea why that happens.

Thanks for the link. I found a lot allready but this one really sums it up.

Thank you very much for the hints on screenrotator. With manjaro-KDE, it was easy to install on pamac and worked flawlessly out of the box. Great!

Hi,

I had the same issue (X1 yoga gen 4 + plasma 5.22) and solved it with
1. screenrotator
2. in system settings -> graphic tablet -> tablet I checked "autorotate with screen" and "invert auto-rotation".

So you haven't found an inbuilt method to get the tablet rotated in sync to the screen yet?
I've just opened https://bugs.kde.org/show_bug.cgi?id=463539 for the same issue still present in Kubuntu 22.04 (fresh install), at least on my Acer Spin SP313 (convertible like the Yoga).
