Pointer/touchpad acceleration bias configuration values not loaded at startup

Version

v2.25.2

Environment

OS: Ubuntu 24.04

What happened? What did you expect to happen?

When using a live config file, pointer_acceleration_bias and touchpad_acceleration_bias (and maybe others) are not set at startup. If the file is modified then the values are set correctly. On the other hand keymap does get set correctly at startup.

Reproduction steps

• Create a configuration file at ~/.config/mir_demo_server.live-config with high values for acceleration bias, e.g. :

pointer_acceleration=adaptive
pointer_acceleration_bias=1.0

touchpad_click_mode=clickfinger
touchpad_acceleration=adaptive
touchpad_acceleration_bias=1.0

• Switch to a tty and run mir_demo_server
• Test mouse and touchpad movement, movement should be normal
• Switch to another tty, run touch ~/.config/mir_demo_server.live-config
• Test mouse and touchpad movement again, movement should now be very fast

Thanks for the report! Will leave it here in case someone in the community wants to pick this up, should be a tractable one to fix.
