Subject: bug#35574: bcm5974 touchpad is not recognized as touchpad
Date: Sun, 5 May 2019 08:54:11 +0200 [thread overview]
Message-ID: <20190505065411.2rb5aqaaxywc4qvk@pelzflorian.localdomain> (raw)
On *some* reboots my Macbook’s touchpad does not work properly; it
behaves like mouse wheel, I can only scroll. Only when I press it
down, I can move the pointer to the right, but never to the left.
This happens both with synaptics and libinput driver.
Restarting xorg-server does not help; this appears to be an issue with
the order in which udev rules are applied.
Apparently my bcm5974 touchpad is recognized by udev as a mouse
sometimes (?), because when diffing /var/log/gdm/greeter.log I see a
mouse being recognized (it is never called bcm5974) instead of a
bcm5974 touchpad.
$ sudo diff /var/log/gdm/greeter.log.1 /var/log/gdm/greeter.log.2
