Support and Help
1

Ubuntu Version: Lubuntu 24.04 LTS noble

Desktop Environment (if applicable): LXQt

Problem Description:
The pointer/cursor (“mouse arrow”) is upside down, i.e. it points towards the bottom of the screen.

Relevant System Information:
Machine is a Microtech e-tab Pro LTE ETP101WL64 tablet.

What I’ve Tried:
I’ve uninstalled iio-sensor-proxy and rebooted; the pointer/cursor was still upside down.
I’ve messed with xinput set-prop “Coordinate Transformation Matrix”; the pointer/cursor was still upside down.

Welcome to Ubuntu Discourse and thanks for sharing your findings :slight_smile:

If you mark your post as the Solution it will also help others find it if they face similar issues.

Thanks.

Thanks :slight_smile: I was wondering how to do that. I can see a square with a checkmark under your message, but not under my opening post. Maybe only replies can be solutions?

What worked
Following Disappearing pointer - #8 by wxl I’ve created

/etc/X11/xorg.conf.d/50-customswpointer.conf

Following the paper trail, it seems the ultimate suggested solution is to use the software cursor:

Section "Device"
   Identifier "device1"
   Option "SWcursor"
EndSection

Comments suggest it’s ugly and may not work. Barring all of Alan’s wonderful suggestions, I might give that a go. Thanks!
For anyone reading this in the future: go to a virtual terminal (e.g. CtrlAltF3) and login. Then, stop the display manager with sudo systemctl stop display-manager. Then start it back up with sudo systemctl start display-manager. This will get you back to your typical login screen. Don’t do that inside of X because it does not actually kill X.
