Description dmatteo002 2025-11-30 18:14:43 UTC
SUMMARY
It is currently impossible to calibrate the drawing tablet, as when entering the calibrate full screen page the cursors disappear:
1. the mouse cursor strangely seem to only be visible in the middle of the screen
2. the tablet cursor is totally not visible (but exist and work)

STEPS TO REPRODUCE
1. Open systemsetting
2. Open "Drawing Tablet" page -> "Pen" subpage

OBSERVED RESULT
The cursor is invisible

EXPECTED RESULT
The cursor should be visible

This is intentional, but not well explained. The whole point of calibrating is to change the (bad) relationship between the detected position and where you stylus actually is. If we show the cursor, people will just tap where the cursor lies which defeats the entire purpose of calibration.

That doesn't feel right, are you sure it's actually visible in the calibration window?

1. How should you calibrate then? Clicking the most extreme point of the tablet? If yes that is pretty difficult on most screen less tablet (especially because it take a single click. Maybe it would be better to make the user move the cursor around and take the most extreme position that it pass through?

2. yes it is indeed visible both the mouse and the tablet cursor are visible when hovering the button. Which look quite strange. 

3. considering that, that screen cover all mouse,... it probably should be possible to exit from it by using esc. Currently the only way to

3. considering that, that screen cover all mouse,... it probably should be possible to exit from it by using ESC. Currently the only way to exit it (for what I know) is to use blindly the mouse or to using tab navigation.

I will split these points into separate bugs, if they are considered valid problems.
