Magic Mouse: lost third button and scrolling following update

Hello,

after doing an update yesterday (former one was about 1 month ago, I don't remember what kernel/Xorg version I was running before then), I lost the third button and all scrolling on my magic mouse v1.

Here are some informations on my system:

• computer → ThinkPad X1 Carbon 4th
• uname -r → 5.1.8-arch1-1-ARCH
• X → X.Org X Server 1.20.5

Here are some outputs about the installation :

% systool -v -m hid_magicmouse
Module = "hid_magicmouse"

  Attributes:
    coresize            = "20480"
    initsize            = "0"
    initstate           = "live"
    refcnt              = "0"
    srcversion          = "C6C55FB459B6C0361588C3A"
    taint               = ""
    uevent              = <store method only>

  Parameters:
    emulate_3button     = "Y"
    emulate_scroll_wheel= "Y"
    report_undeciphered = "N"
    scroll_acceleration = "N"
    scroll_speed        = "32"

  Sections:

	libinput Drag Lock Buttons (292):	<no items>

When I run xev, and I try clicking on button or scrolling, the only events I'm getting are:

ButtonPress event, serial 38, synthetic NO, window 0x2c00001,
    root 0x16d, subw 0x2c00002, time 24651965, (67,50), root:(1410,706),

    state 0x10, button 3, same_screen YES

ButtonRelease event, serial 38, synthetic NO, window 0x2c00001,

    state 0x410, button 3, same_screen YES

I removed the LeaveNotify, MotionNotify events as they are non-relevant, but I never get a button 2 or button 4/5 scroll events.

In Xorg.0.log, all I get upon connection is:

[  1287.794] (II) config/udev: Adding input device Magic Mouse V1 (/dev/input/mouse3)
[  1287.794] (II) No input driver specified, ignoring this device.

[  1287.871] (II) systemd-logind: releasing fd for 13:87

(edit : the log above is from /var/log which is wrong, force of habit… All the following logs were taken with journalctl)

I have no configuration in /etc/X11/xorg.conf.d/ relating to the mouse, and I only setup /etc/bluetooth/input.conf with UserspaceHID=true because of some BT disconnections I'm getting (which got better with that, but I'm still getting some issues but that might be another issue) since the upgrade.

So my guess is that something's not right between the kernel and Xorg, or within Xorg's configuration, but I'm not sure where to dig next. It'd be great if someone could give me some help on that issue! I never realised how much I'm used to scrolling and middle click up until I don't have them anymore!

Cheers

Re: Magic Mouse: lost third button and scrolling following update

I switched today from a Thinkpad X140 to a A275 and I'm wondering why I'm also unable to use the middle button for scrolling. I'm also unable to mark text with the Trackpoint. Firing up xev shows that a ButtonReleased event directly follows on the ButtonPressed event, keeping the button pressed seems not be recognized also in your case?

Edit: Issue was a wrong proto of psmouse in my case, so it seems not to be related.

Re: Magic Mouse: lost third button and scrolling following update

Looks like I'm not the only one to have met this regression: https://forums.gentoo.org/viewtopic-t-1 … art-0.html same history, but no solutions or explanations. One difference I'm noticing though, is that the poster is using evdev whereas I'm using libinput, so I might try restarting X with evdev installed and see if it changes anything ¯\_(ツ)_/¯

Re: Magic Mouse: lost third button and scrolling following update

So I tried with evdev, it did not change the xorg driver, so I forced evdev to manage the mouse:

Section "InputClass"
Identifier "Apple Magic Mouse" # This can be anything
MatchIsPointer "on"
MatchDevicePath "/dev/input/event*"
MatchProduct "Magic Mouse V1"
Driver "evdev" # From '/var/log/Xorg.0.log' after mouse connected
EndSection

and here's what I got:

So I wanted to say hurra seeing that, but no luck having scroll or third button… I looked at the new xinput output:

Device 'Magic Mouse V1':
	Device Enabled (153):	1
	Coordinate Transformation Matrix (155):	1.000000, 0.000000, 0.000000, 0.000000, 1.000000, 0.000000, 0.000000, 0.000000, 1.000000

	Evdev Third Button Emulation Threshold (334):	20
	Evdev Wheel Emulation (335):	1
	Evdev Wheel Emulation Axes (336):	0, 0, 4, 5
	Evdev Wheel Emulation Inertia (337):	10
	Evdev Wheel Emulation Timeout (338):	200
	Evdev Wheel Emulation Button (339):	4
	Evdev Drag Lock Buttons (340):	0

and it looks like it's all well configured. But still, neither evtest or xev report anything but button one and three clicks (left/right).

Re: Magic Mouse: lost third button and scrolling following update

hm… I tried to look at what the mouse character devices returns, and when I run od -x on either /dev/event/mouseX or /dev/event/mouseY there's nothing that gets out on scroll, and data changes from button 1 to button 3, but nothing in between. It confirms the evtest results.

That means the culprit is definitely not Xorg but the hid_magicmouse module…

Re: Magic Mouse: lost third button and scrolling following update

The most likely candidate here is the kernel, downgrade/switch to linux LTS to check if you can reproduce.

On another note, why - and I hope this is a typo --- are you still using xorg 1.19.6 ? partial upgrades are unsupported

Re: Magic Mouse: lost third button and scrolling following update

On my first report I looked at the Xorg.0.log in /var/log (force of habit, still trying to get used to journalctl). For the other reports I looked up and found out that I shall use journalctl -e _COMM=gdm-x-session for that. So my Xorg is actually : X.Org X Server 1.20.5

I'm _always_ running upgrades with pacman -Syu so I never expected partial upgrades, especially on core packages like Xorg. I want to minimise the risk of a failed upgrade.

Also, if I got a regression on upgrade, I don't think I just simply rollback, I should rather dig and understand the cause of the problem so I can help others and if needed contribute to fix the issue.

Re: Magic Mouse: lost third button and scrolling following update

We can get to the digging once we've identified where the regression occured. Check your pacman log for what you've had installed as your previous and working kernel, once we have a known version range we can dig out the exact breaking change

Re: Magic Mouse: lost third button and scrolling following update

from pacman:

[2019-06-12 17:53] [ALPM] upgraded libevdev (1.6.0-1 -> 1.7.0-1)
[2019-06-12 17:53] [ALPM] upgraded libinput (1.12.6-1 -> 1.13.2-1)
[2019-06-12 18:03] [ALPM] upgraded linux (5.0.3.arch1-1 -> 5.1.8.arch1-1)
[2019-06-12 18:06] [ALPM] upgraded xorg-server (1.20.4-1 -> 1.20.5-1)

looks like what I thought was 1 month actually has been 3 months… Damn time is fleeing so fast -_-

Re: Magic Mouse: lost third button and scrolling following update

So on the kernel upstream no major changes has happened in between those two versions on the magic mouse driver:

https://github.com/torvalds/linux/commi … gicmouse.c

I also double checked that my device Id was matching the module's, and it does: 

#define USB_DEVICE_ID_APPLE_MAGICMOUSE	0x030d

vs

evdev: Magic Mouse V1: Vendor 0x5ac Product 0x30d

Re: Magic Mouse: lost third button and scrolling following update

and finally output of the kernel's logs:

too bad `journalctl -k` doesn't show logs for before the upgrade :-/
