Subject: Regression with Lenovo ThinkPad Compact USB Keyboard
Date: Fri, 16 Feb 2024 12:51:46 +0100 [thread overview]
Message-ID: <a29d56d2-c440-4a26-a9ac-014595d2ae8c@gmail.com> (raw)
Dear developers,
(sorry for the long CC list, it looks quite long to me, but I tried to
follow the issue reporting guide as closely as possible)
Since patches [1], [2] and [3] were applied to the kernel, there is a
regression with Lenovo ThinkPad Compact USB Keyboard (old model, not II).
[1]
https://github.com/torvalds/linux/commit/46a0a2c96f0f47628190f122c2e3d879e590bcbe
[2]
https://github.com/torvalds/linux/commit/2f2bd7cbd1d1548137b351040dc4e037d18cdfdc
[3]
https://github.com/torvalds/linux/commit/43527a0094c10dfbf0d5a2e7979395a38de3ff65
The regression is that a middle click is performed when releasing middle
button after wheel emulation.
The bug appears randomly, it can be after 5 minutes or 1 hour of
keyboard usage, and can only be worked around by unplugging/re-plugging
the keyboard. (I ended up resorting to simulate an unplug/replug, with a
script which echoes 0 then 1 to /sys/bus/usb/devices/<id>/authorized,
since I was afraid to damage the Micro-USB outlet by physically
unplugging/re-plugging too much).
Those spurious clicks are very annoying, since they can open links in
new tabs when scrolling in Firefox, or pasting text when scrolling in
terminals, or other unwanted stuff.
I witnessed it with latest kernels (Debian unstable) as well as stable
kernels (Debian 12 Bookworm, stable).
On Debian Stable, the last working kernel was 5.10.127, the regression
appeared in 5.10.136 (i read all changelogs on kernel.org between those
two releases but couldn't find anything about hid-lenovo, so I can't
tell exactly in which release the regression appeared, Debian upgraded
directly from .127 to .136).
I reported it in Debian [4], and apparently I'm not the only person
suffering from it [5].
[4] https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1058758#32
[5] https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1058758#42
I would understand that such bugs would end up in a development kernel
like the ones provided by Debian Unstable, but not with stable kernels
like the ones provided by Debian Stable.
