Trackpad turns into a mouse after suspend

[zoff]

It’s not often, but it’s fairly consistent. When my laptop goes into suspend, and then it wakes up, the trackpad effectively becomes a mouse. I notice this behavior for several reasons:

1. Two finger scrolling (and any scrolling for that matter) stops working
2. Acceleration is now controlled by the mouse preferences and not by the trackpad preferences.
3. Two finger right click stops working.

A reboot always fixed the issue.

Any help would be much obliged. This is an absolute pain when it happens.

It sounds like it is dropping into the PS/2 Emulation Mode. You could try disabling that mode in BIOS.

[zoff]

Just tried that, will report back if it resolves the issue.

[Kieran_Levin]

We lengthened the time that we will wait for the trackpad to be handled by the OS driver in bios 3.05 to try and improve this. I suspect that if you wiggle the mouse in modern standby, sometimes the OS takes longer than about 400ms to service the trackpad interrupt causing the firmware to drop into ps2 mode.
But disabling ps2 emulation should fix this in any older firmware.

How does one apply a newer BIOS firmware update?

I also saw this issue in Ubuntu 21.04 but haven’t had it happen again since disabling PS/2 Emulation Mode in BIOS as suggested.

[zoff]

Confirming the solution offered by @nrp worked. I have not encountered this issue since disabling PS/2 Emulation Mode.
