psmouse - TrackPoint and TouchPad both enabled adds ~6s to boot time

carbohydrates · 2014-08-19 18:29:04

I've done a lot of searching on this issue - others have had this problem, but it looks like nobody has ever figured this out.

The problem presents as a 6-10s period of time after starting X where everything works except the touchpad/trackpoint - keyboard input works fine, I just can't move the mouse for 6-10 seconds.

This triples the amount of time it takes to get to a fully working system vs. just having one or the other enabled in BIOS.

----------

Here are the relevant logs; this is always at the very end of the boot process, so I grabbed logs with "dmesg | tail -n30 > ~/log/name.txt" and edited them to include only the relevant parts. Everything not included here is more or less identical between boots. I can include more if anyone thinks it would help.

...but that doesn't really help any more than the dmesg output. Anyone have further troubleshooting suggestions for this? I've tried just about everything I can think of, and I've been reading up on stuff related to this for the past two weeks - and I've made no progress.

Does it matter that they are TrackPoint and TouchPad? Or is this a general problem when udev has to detect two mice?

X might start faster without input device hotplugging. This would require you to add "InputDevice" sections to xorg.conf where you assign the driver "synaptics" to one and "evdev" to the other.

Hey, thanks for the response. It does matter that they're a TrackPoint and Touchpad - if I disable one or the other, and attach an external mouse, it works perfectly. No delay.

X starts plenty fast either way - it's just the detection/functionality of input devices that's slow. I'll start looking into how to disable hotplugging, though, to see if it'll help.

Something new I've found - giving psmouse the option 'proto=bare' causes them both to be detected and function immediately on boot - but I lose some of the more advanced functions of both. I'm looking into how to get some of that functionality back now, as well.

The "pass through" aspect of these devices seems to be what's causing the delay. With 'proto=bare', they're detected as a generic PS/2 mouse, with no pass-through. When just one or the other is enabled, there's no pass-through. With two or more separate mice, there's no pass-through. But when they're both enabled - there is a pass-through, and there's also that delay.

Could it be that both devices use the same physical communication bus? Does the hardware work as expected under Windows? Would it be possible to load the appropriate module for one device later? Or are there restrictions?

I have the same problem on my Thinkpad X220. Will keep an eye on this thread.

Hi,
i have the same problem on gentoo (but with the trackpoint, not the touchpad) on a Thinkpad t440p. Disabling the Trackpoint reduces the kernel loading time from 6 sekonds to 1.5 seconds ...

as the dmesg line "psmouse serio2: trackpoint: IBM TrackPoint firmware: 0x0e, buttons: 3/3" was the part to blame, i disabled the kernel driver "CONFIG_MOUSE_PS2_TRACKPOINT" and the line disapeared. Interstingly the kernel was still slow booting. Therefore, removing the driver, does not help. only disabling the trackpoint in the uefi seems to work.

i have opened a bug report on kernel.org: https://bugzilla.kernel.org/show_bug.cgi?id=98071
