Package: src:linux
Version: 6.1.90-1
Severity: important
X-Debbugs-Cc: casa...@acm.org
The system information associated to the bug MUST be taken from bug report
1071236.
The reason: the problem depends on the kernel version; the present bug report
is sent from the problematic computer, but running a different kernel than the
one experiencing trouble.
The problem:
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 (after a few minutes)
symptoms such as those listed below occur with increasing frequency, till the
system is nearly unusable (after about 20 to 30 minutes):
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 for a short while.
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. 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 the on/off hardware
button).
The problem takes place with Gnome, classic or not, on X.org or not, and also
on XFCE. Two different mice were used, with the same effect. It always looks as
if linux at times ceases recognizing events from input devices, and at other
times generates random phantom events.
Other machines (3 models from 2 other manufacturers) previously upgraded from
Debian 11 to Debian 12 do not exhibit this problem.
Attempted workaround: booting the L570 (upgraded to Debian 12) with the kernel
of its previous Debian 11 installation. Thus, when relying upon kernel
linux-image-5.10.0-29-amd64
instead of
linux-image-6.1.0-21-amd64
mouse, trackpad, and keyboard work again without problem.
I welcome any hint at what could have caused such a behaviour, and any
suggestion as to how to get rid of it. Could it be that a package became
somehow corrupted during installation? In which case, how to detect which one
and how to correct it?
Many thanks in advance
