X events getting clogged up?

In case you don't know, the touchpad controller is wired via a serial port, (I2C I think), to the keyboard controller. Then the keyboard controller is wired to an internal USB 2.0 hub. Which is then wired to a RK3399 USB 2.0 port. Since these are low speed devices, it should work fine.

From what I understand, (and my knowledge is limited), the touchpad firmware has a minor bug which causes it to send out empty or useless packets. Nothing that would cause Linux to crash. Newer kernel drivers will toss out those packets, reducing the overhead. But, since you are on the original Mr.Fixit Debian, it might not have the "fix". So the packets leave the kernel and X-Windows drivers have to then toss them out.

Anyway, that's about what I know. Their IS a problem with the touchpad. A fix in the kernel driver can work around it. And in general, most people aren't affected by it.


Ideally, the keyboard replacement firmware project would either fix those touchpad packets or toss them. At least until we can get the touchpad firmware fixed.

I can get you a link to the replacement keyboard firmware project, if you want. (Their are forum postings about it too...)
