Bug ID: 487803
Summary: "Terminate X" application prompt does not work for
unresponsive processes
Classification: Plasma
Product: kwin
Version: 6.0.4
Platform: Manjaro
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: core
Assignee: kwin-bugs-n...@kde.org
Reporter: solla...@gmail.com
Target Milestone: ---
SUMMARY
To give a bit of context, when an application freezes or becomes unresponsive,
it becomes gray and will eventually show a dialog titled "Not Responding -
Window Manager". This window gives you two options: "Terminate X", where X is
the name of the process, and "Wait Longer".
Selecting "Wait Longer" will close the dialog temporarily.
Selecting "Terminate X" is meant to terminate the application and close all of
its windows, as is mentioned in the dialog.
I've found that this option almost never works. Neither does the default "Quit
Application" option in System Monitor. Instead you have to go to "Send Signal"
and explicitely send it a KILL signal to get it to close, which is inconvenient
and annoying when there are so many easier to reach (and yet non-functional)
options for closing such applications.
STEPS TO REPRODUCE
The most realiable way to reproduce a unresponsive application is to take
advantage of a bug within Bottles that allows you to shutdown the internal soda
runner without terminating the application front-end.
First you will need to install the Bottles flatpak. Create a bottle, name it
"Common" then configure it, and install Inkscape 0.92.5 using the windows
installer (here: https://inkscape.org/en-gb/release/inkscape-0.92/?latest=1 )
Next you will want to configure SVG files to open using the bottled Inkscape.
In System Settings, go to File Associations > svg+xml and add a new entry with
the following parameters and set it as the default option.
Name: Inkscape
Comment: Launch Inkscape using Bottles.
Program: flatpak
Arguments: run --command=bottles-cli com.usebottles.bottles run -p Inkscape -b
Common -- '"%U"'
With setup complete:
1. Create 2 svg files
2. Open both in the bottled inkscape by clicking/double-clicking them
3. Once both are opened and the windows have loaded, close the you opened
**last**
4. Attempt to close the remaining window
If done correctly you should now have one inkscape window open that is not
responding which you will not be able to close through any means other than a
direct sig-kill towards the parent bottles process.
OBSERVED RESULT
You can attempt to close it using the (x) which will prompt the aforementioned
dialog. After that clicking "Terminate inkscape.exe" appears to be no different
from clicking "Wait Longer". The dialog will close, and you can continue to
click (x) on the inkscape window to prompt it to re-appear.
You can escalate to System Monitor and try to close it by right-clicking the
Bottles process and selecting "Quit Application" but this simlarly has no
effect.
EXPECTED RESULT
Clicking "Terminate inkscape.exe" or "Quit Application" should cause the window
to close immediatly.
