Mouse pointer not showing up

[benoit74]

Mouse pointer is not showing up on Chromium window.

Double clicking the mouse left button is selecting / unselecting text, so mouse is more or less operating.

However it seems that trackpad is not making the pointer move.

I tried to plug an external (RF USB dongle) CHERRY mousse. This time it looks like the pointer is moving, because when double clicking the text selected is not always the same after moving the mouse. But still no pointer.

Keyboard is operating properly.

Current device is an amd64 architecture, but I previously experienced the same issue on a aarch64 platform.

Hi there,

Can I check if you had the SHOW_CURSOR environment variable set to 1? By default we hide the cursor since most users will have the block in kiosk mode for digital signage applications.

Shame on me ... I didn't customized this variable at all, so you've probably the proper explanation ... Sorry for that, I'll close the issue, and reopen should there be another problem, but it now seem pretty obvious there is no issue besides the person sitting in front of my screen and keyboard ^^
