[Bug 1904671] Re: After a certain amount of time after the session is launched, mouse clicks are no longer accepted

[TAKAHASHI Hidetsugu]

Thank you response Mr.Chris.


> You've filed this bug against ubuntu-release-upgrader, but don't seem to describe a problem related to the upgrade process, so I'm a little confused by that.

I saw this after upgrading with the `apt full-upgrate` command, so I
chose `ubuntu-release-upgrader` and reported a bug. I'm sorry, my
mistake.


> I get the (uneducated) feeling that it relates to GNOME, or the kernel (linux) but I'm unsure sorry. I would likely explore that probably using `xev` to ensure the mouse events are still recognized (ie. leaving that in a corner with terminal window visible)...

I'm unfortunately, I didn't know how to output real-time event logs in
GNOME or the kernel. I may be able to investigate the cause with `xev`.
Thanks for the helpful information.


By the way, here's my feeling that I just noticed.

The contents of number 3 are
"Leave it for a few dozen minutes without doing anything."
may be correct.

Because I encountered this phenomenon when I took a few dozen separate
seats without locking the screen and tried to operate it again.


I'm new to reporting bug and I'm sure there is some information missing from the information I provide.

I will continue to look into this phenomenon and get back to you as best
I can.

Title:
  After a certain amount of time after the session is launched, mouse
  clicks are no longer accepted

Status in ubuntu-release-upgrader package in Ubuntu:
  New

Bug description:
  X11, Wayland, the Gnome Desktop does not recognize mouse clicks and
  drags after several tens of minutes after launching. However, it does
  recognize the movement of the mouse cursor.

  [How To Reploduce]

  1. login in a Gnome session.
  2. launch some applications.
  3. use it for a few dozen minutes.
  4. attempt to click and drag with a mouse or other pointing device.

  [Actual Result]

  I can no longer select mouse click application windows, activity
  buttons, dashes, etc.

  [Expect Result]

  I will accept mouse clicks until the end of the session, and possibly
  hope that the event is executed when the click is made.
