#111772 — Bug#1071236: general: keyboard, mouse, and trackpad behave inconsistently; seemingly phantom input device events occur unpredictably

Package: general
Severity: important
X-Debbugs-Cc: casaise@acm.org

Dear Maintainer,

After uprading my laptop (Lenovo L570) from Debian 11 to Debian 12, the system
appears to
handle input devices (keyboard, trackpad, mouse) inconsistently. Initially,
everything works
fine, but progressively symptoms such as those listed below occur with
increasing frequency,
till the system is nearly unusable:

1) When typing text, the cursor suddenly relocates to another position,
typically several lines
upwards.

2) The mouse buttons have no effect (e.g. to close a window, or to activate a
menu entry in an
application or the taskbar, or to move to a different workspace). It is then
necessary to use the
buttons on the trackpad -- then the mouse functions again.

3) When resizing a window with the mouse, the handles have either no effect at
all, or cannot
be released to stop resizing. Again, clicking on the trackpad "resets" the
mouse.

4) Contextual menus suddenly pop up without having been invoked. Again,
clicking somewhere is
required to make them disappear.

5) When using a terminal window, the keyboard suddenly stops working. I have
found no other solution
than killing the window and reopening another one.

6) On a variety of applications (terminal window, browser, editor), the system
sets itself in a state
as if the user wanted to make a copy of a text region. Moving the mouse of
trackpad selects a portion
of the text on the screen.

7) Buttons on mouse and trackpad stop operating; shutting down the computer can
only be achieved with
a forced shutdown (long press on on the on/off hardware button).

The problem takes place with Gnome, classic or not, on X.org or not, and on
XFCE.

I had upgraded three other old machines (3 models from 2 other manufacturers)
to Debian 12 -- none
exhibited that problem so far.

I would appreciate any kind of information about how to put things in order.

#111775 — Re: Bug#1071236: general: keyboard, mouse, and trackpad behave inconsistently; seemingly phantom input device events occur unpredictably

Hello,

you filed a general bug against debian. At most it should be directed towards 
the kernel or libinput or evdev.

Anyway, it seems to me like a hardware problem.

I have a thinkpad in which putting a new keyboard solved a lot of problems 
with the input.

So I am closing the bug.

If you can test with a new keyboard (making sure the current is disconnected) 
and the problem persists, you should open a bug against the actual component 
that is creating the issue. Since you said you tried both wayland and xorg, 
that would be the kernel or libinput.

Best of luck!

Many thanks for the prompt handling of my report.

Unfortunately, I do not have an external keyboard to test with.

What I did, however, was to boot with the kernel of the previous Debian 
11 Bullseye installation. In other words, instead of relying upon kernel

6.1.0-21-amd64

I used

5.10.0-29-amd64

Everything works perfectly. After several hours, I have yet to 
experience any trouble with keyboard, mouse, or trackpad. With kernel 
6.1.0-21, device input starts going haywire after about about 5 minutes, 
at which point the system gets increasingly unstable, and becomes 
unusable after 20-30 minutes.

I really wonder what could cause such a trouble with the newer kernel.

Is there a way to shift the report to the kernel category?

Many thanks

Eduardo Casais

Hello,

you can run "reportbug packagename" to report against a specific package.

You can find out how your kernel package is called with 

dpkg -l "linux-image-*"
