I'll see if I can attach a sys log, but I'm not sure how to do it:
- will the syslog be added even when booting from USB?
- is the partition where the syslog is written readable on a Windows/Mac machine?

will the syslog be added even when booting from USB?
Yes, as long as you get to the desktop successfully (and the USB stick is writeable.)
is the partition where the syslog is written readable on a Windows/Mac machine?
Probably not (maybe via FUSE but I don't know if anyone has gotten BFS-FUSE to work with OSXFUSE.) Linux can read BFS natively at least.

Better late than never: I tried the latest Beta 5 on a Surface Book and the same happens. It boots to the desktop but mouse/trackpad won't work.
I found a way to extract the syslog this time.

ps2 as in old mouse keyboard interface?
Let me know if you need me to do more tests/debug.

I tried disabling the ps2 kernel module in the boot menu and it worked: I now have trackpad (no scrolling it seems though) and keyboard working.
Is there a way to disable it permanentely?

That doesn't make much sense. If these devices are attached via the PS/2 bus, how does disabling the PS/2 driver get them to work?
What input devices do you have in /dev? How do they show up in Input preferences?
comment:10 by , 5 weeks ago
There is no PS/2 device in the Surface Book from what I know. My assumption was that for some reason, the PS/2 kernel driver error caused the problem? Or maybe there is some sort of PS/2 emulation in UEFI?
I'll add more details tomorrow.
comment:11 by , 5 weeks ago
Many internal keyboards and trackpads are attached via PS/2 internally even on modern UEFI hardware. The only real alternative is I2C HID which we don't support out of the box yet.

It seems to be detected as USB: I attached a screenshot of the input preferences window. Note that for some reason, both seem to be detected twice. When clicking on the touchpad, it highlights the left button of the mouse on both "USB Mouse 1" & "USB Tablet 1".
