Plasma taskbar and background disappear when external monitor goes wakes up

[imanj]

Hello,

For a month or so now I have been having the problem that when my external monitor wakes up (because my laptop has been idle for some time) the task bar disappears (as well as my desktop background).

I’m able to temporarily resolve the issue in one of two ways:

1. I unplug/replug the external monitor. Everything is as it should be down.
2. I run kquitapp5 plasmashell; kstart5 plasmashell

Ideally though everything would just work as it used to.

My current setup is:

• Laptop connected to external monitor via HDMI. The laptop screen is set to disabled.
• I’m using 24.2.1 Manjaro
• Kernel: 6.1.119-1-MANJARO
• Plasmashell version is 6.2.4
• I’m using X11

What information could I look for/provide to get to the bottom of what is going on?

Thanks,

[Mirdarthos]

Hi @imanj,

@imanj

Kernel: 6.1.119-1-MANJARO

Youu could try a different kernel. Although this one is LTS, a new one might be a good idea. Try 6.6 or even 6.12, the latest LTS versions.

If that doesn’t work, perhaps a workaround would be a systemd timer that does the restart automatically for you on wakeup?

I have a hotkey bound to do the restart so I am making it work, but ideally I’d figure out what the actual underlying issue is.

Will update with logs/info upon the next incident to keep them short.

I’d figure out what the actual underlying issue is.

As I mentioned, try a different kernel.

Kubuntu in November… seems this has been an issue since Plasma 6.

@imanj

keep them short.

Please don’t do that. Give the complete output. See:

Finding errors for specific boot

journalctl --priority=warning..crit --no-pager --boot=-1

Where:

• The --priority=warning..err argument limits the output to warnings and errors only;
• the --no-pager formats the output nicely for use here, on the forum; and
• the --boot=-1 argument limits the output to log messages from the previous boot. This can be adjusted to -2 for the boot before that, -3 to the boot before that, and so on and so forth.

Providing terminal output

---

Tip

When posting terminal output, copy the output and paste it here, wrapped in three (3) backticks, before AND after the pasted text. Like this:

```
pasted text
```

Or three (3) tilde signs, like this:

~~~
pasted text
~~~

This will just cause it to be rendered like this:

Sed
sollicitudin dolor
eget nisl elit id
condimentum
arcu erat varius
cursus sem quis eros.

Instead of like this:

Sed sollicitudin dolor eget nisl elit id condimentum arcu erat varius cursus sem quis eros.

Alternatively, paste the text you wish to format as terminal output, select all pasted text, and click the </> button on the taskbar. This will indent the whole pasted section with one TAB, causing it to render the same way as described above.

Thereby increasing legibility thus making it easier for those trying to provide assistance.

For more information, please see:

@Fabby

On this forum here you need to have Trust Level 1 (=TL1) to be able to post screenshots and links in-line.

That’s dumb! Why is that?

Well, that’s because on our old forum we got tons of screenshots of text, links to SPAM, PR0N and other things you don’t want on a forum, so all the new users are prohibited from posting links and pics because of a few bad actors.

---

Additionally

If your language isn’t English, please prepend any and all terminal commands with LC_ALL=C. For example:

LC_ALL=C bluetoothctl

This will just cause the terminal output to be in English, making it easier to understand and debug.

@imanj

I run kquitapp5 plasmashell; kstart5 plasmashell

I’d be surprised if this was working very well … considering we are on Plasma 6 and as such the correct executables are kquitapp6 and kstart … though this will not quite work on wayland as it did on X11. So

kquitapp6 plasmashell; kstart plasmashell

In general you may instead wish to try

systemctl restart --user plasma-plasmashell

Though maybe theres something else preferable in dbus somewhere.

I tried upgrading the kernel to 6.6.65-1-MANJARO but the problem persists.

Here are my journalctl and inxi output. The journalctl output was too big to be pasted here, but I ran journalctl --priority=warning..crit --no-pager --boot=-1 to produce it.

Mod edit:- It seems you were having some difficulty with formatting. I’ve taken the liberty of fixing that for you. If you like, click the ‘Edit’ button to see how it was done. Cheers.

See if changing your Session Restore settings might help:

1. Open System Settings:

2. Go to: Session → Desktop Session → Session Restore

3. Make sure the following is selected;

• Start with an empty session

4. Logout (or reboot if you can)

---

There was a fairly recent issue KDE Plasma hangs on Shutdown, Restart and Logout that might be related – the above was the workaround.

@imanj

Swap:
  Alert: No swap data was found.

Additionally, you might wish add some swap space at your earliest convenience. Currently you have none configured.

• Swap (Manjaro Wiki)

Tried this, rebooted, but unfortunately still see the same behaviour.

I’m guessing you missed the post #7 from @Ben

The linked KDE report seems to fit your description perfectly. It looks without doubt to be a KDE issue. You might monitor that KDE thread, or search for the respective bug report.

• KDE Bugtracking System

Panel disappears when the monitor wakes up from sleep (off) state

The issue would appear not to be Manjaro related.

Regards.

[imanj]

No, does not appear to be, but I was hopeful a solution might come to light.

I’ll add my two cents there and see what comes of it.

Thanks for all the help and assistance

[codeliger]

I am having the same issue. Its been like this for a few weeks or maybe longer now i lost track. It happened after a pacman -Syu

[soundofthunder]

@codeliger

I am having the same issue.

Then, the same resolution applies.

In this case, the issue seems not to be Manjaro related. By all means follow previously given links to the issue raised at KDE.

Note that so-called “me too” posts are generally discouraged; they typically amount to noise.

Regards.

I’ve fixed that issue by reverting to Plasma 6.1.5 using Timeshift.

I got the same issue after upgrading to Plasma 6.2.4 and it was caused by this update.

[soundofthunder]

@adem

I got the same issue after upgrading to Plasma 6.2.4 and it was caused by this update.

There is nothing listed in Known Issues and Solutions in the 2024-11-30 Stable Update announcement you referenced.

The item Plasma 6.2 might create a black screen when using X11 and default theme mentions a “black lock screen when using Breeze Plasma style, but controls are all there and remain interactive” but that’s not what was described here.

The report on KDE Discuss (linked previously) is a match for the OP’s issue, which in turn is possibly related to KDE bug #497806

Nonetheless, thank you for your input.
