Bug ID: 506124<br>
Summary: Konsole fails to display command prompt after some<br>
scripts complete<br>
Classification: Applications<br>
Product: konsole<br>
Version First 25.04.2<br>
Reported In:<br>
Platform: Arch Linux<br>
OS: Linux<br>
Status: REPORTED<br>
Severity: normal<br>
Priority: NOR<br>
Component: general<br>
Assignee: <a href="mailto:konsole-devel@kde.org" target="_blank">konsole-devel@kde.org</a><br>
Reporter: <a href="mailto:dwarf.nordar@gmail.com" target="_blank">dwarf.nordar@gmail.com</a><br>
Target Milestone: ---<br>
<br>
== SUMMARY ==<br>
After a script that produces continuous output to the terminal finishes (e.g.,<br>
using `wget --show-progress` or a simple loop), the Konsole prompt (PS1) is not<br>
rendered automatically. The terminal itself is not frozen: pressing the Enter<br>
key makes the cursor move to a new line, and after that, the prompt may appear.<br>
This indicates a rendering or state issue within Konsole, not a shell or<br>
process hang.<br>
<br>
== STEPS TO REPRODUCE ==<br>
1. Create a simple test script named `test_prompt.sh` with the following<br>
content:<br>
#!/bin/bash<br>
echo "Starting long output..."<br>
for i in {1..50}; do<br>
echo "Line $i of 50"<br>
sleep 0.02<br>
done<br>
echo "Script finished."<br>
# The prompt should appear here, but it doesn't.<br>
<br>
2. Make it executable: `chmod +x test_prompt.sh`<br>
3. Run it in a Konsole tab: `./test_prompt.sh`<br>
<br>
== EXPECTED BEHAVIOR ==<br>
The command prompt (e.g., `user@host:~$`) appears immediately on a new line<br>
after the "Script finished." message is printed.<br>
<br>
== ACTUAL BEHAVIOR ==<br>
A blank line with a blinking cursor appears. The prompt is not rendered. If the<br>
user then presses the Enter key, the prompt appears on the next new line. The<br>
issue is 100% reproducible.<br>
<br>
== DEBUGGING STEPS ALREADY TAKEN (IMPORTANT) ==<br>
We have conducted an extensive debugging session and have ruled out common<br>
causes. This is NOT a configuration issue.<br>
<br>
1. **Shell configuration ruled out:** The issue persists with a completely<br>
empty `~/.bashrc` and a sanitized `/etc/bash.bashrc` (with the window title<br>
setting block commented out).<br>
2. **It works in a sterile environment:** The command `env -i bash --norc`<br>
followed by running the script works correctly, proving the issue is related to<br>
the environment loaded by a normal interactive shell.<br>
3. **strace analysis performed:** `strace` logs confirm that the `bash`<br>
process is NOT hung. It successfully writes the prompt string to the terminal<br>
(via the `write()` syscall) and then correctly enters a `pselect6()` state,<br>
waiting for user input. This strongly suggests Konsole receives the command to<br>
draw the prompt but fails to render it.<br>
4. **Konsole Profile ruled out:** The issue persists even after creating a<br>
new, clean user profile within Konsole.<br>
5. **`reset` command workaround failed:** Adding the `reset` command to the<br>
end of the test script does NOT solve the problem.<br>
<br>
This appears to be a genuine rendering or state management bug within Konsole<br>
itself.<br>
