[SOLVED] Little pb with KDE5

Desiderius · 04-19-2021, 07:22 AM

Hi all

I have installed the latest image of Slackware ARM on my RPI4 with, of course, KDE5 !

Everything is working fine except ... the system configuration window !

When I click on "System configuration", a window appears with a black background and nothing visible inside ( see attachment )!

In spite of this, the window is active and when I move the mouse , I can see some of the various items and from time to time, the right part of the window displays the contents on a white background.

What is happening and how can I fix this problem ?

Good timing! I was just about to test the latest KDE build.

This may be a translation thing, but with the English language set, I cannot find a 'System configuration' in KDE; I'm assuming it's "System Settings".

This is on a fresh installation of -current (which has a KDE upgrade) on the Orange Pi.
Keep an eye on the -current ChangeLog -- assuming the system integration tests pass, I'll push the updates out later today.

Thanks @drmozes

Yes it is what I expected to obtain !

If it can help you, here is what I see when lauching systemsettings5 on a terminal

The updates are making their way out now. Try grabbing them in a few hours now from the master ftp.arm.slackware.com
The updates may resolve it, since it certainly works on a fresh installation.

Hi @drmozes

Full of hope seeing your Change.txt, I have pointed Slackpkg to my French mirror ( where I have checked they have got your changes )

- slackpkg update + install-new + upgrade-all

More than an hour of upgrade where I have seen all the components of KDE been upgraded that finishes without any errors and then ... reboot !

KDE starts normally and shows me the icon of System settings : I click on it and ....... a black window appears once again !

Like before the window is active and, when clicking randomly on the left side of the window, sometimes I got a useful right part ( see image )

I have also tried to launch systemsettings5 on a terminal and it shows the same errors as yesterday.

I have also tried to erase my .kde repository to let KDE build a new one but it has no effect.

I do not know what to do more now : is it a pb with the X driver but all the other windows are correct !

A similar sounding and looking bug was reported here, where the report centres around the video driver.
I don't have an RPI so I can't help you I'm afraid. You could try reinstalling onto other storage if you can, to see if a fresh install fixes it in case it's being affected by something not in ~/.kde.

Desiderius · 04-21-2021, 04:29 AM

Apparently this a bug of KDE mentioned a lot of times on the Internet for many Linux distributions.

It is curious you do not see it.

I have tried to change the graphic driver, to adopt a clear them but nothing has effect on it.

I will check to see if I can reproduce this bug on my Raspberry Pi 4. Unfortunately, I will not be able to check on my Pi 3 models.

netcrawl · 04-21-2021, 11:26 AM

I have the same, or similar issue with my Pi 4 4GB. I haven't found the cause or fix, but I did find a "work-around".

If you can find it, in System Settings--> Configure, change Sidebar View to Icon View. Not a great solution, but at least you can see and access the settings.

mralk3 · 04-21-2021, 01:18 PM

It took a while to get back to you guys because I did a fresh installation. I do not have an exra monitor to plug into the Pi. I tested in a remote desktop session, with tigervnc, which techincally, should be more GPU intensive. I am using all stock settings and that includes window composites. I checked the log file for the vnc session and saw the same deprecation warnings.

By chance did either of you just change your global theme?
Sometimes KDE has a problem with this and you need to log out of KDE and log back into KDE with a new session.

Can each of you do a small test for me?
Create a new user, reboot, log into that user within KDE. Post back here to let me know if you have the same issue with the new user.

I won't be able to test a new account/user for a few hours, but yes, I did change the global theme, a couple of times. I'll try the new user test when time allows, and post results if it's still relevant.

That is fine, what is the output of:

Code:

glxgears -info

As a test, I changed a bunch of settings, managed to crash vncviewer (unrelated), then reconnected, reverted to the default theme. I think the problem is in your user's configuration settings. Quite likely stale files in the home directory.

netcrawl · 04-21-2021, 05:50 PM

Tried as a new user, same result. Even ran as root, same.
Removed a page of GL_Extensions from this:

PHP Code:


			
bash-5.1$ glxgears -info

GL_RENDERER   = llvmpipe (LLVM 11.1.0, 128 bits)

GL_VERSION    = 3.1 Mesa 21.0.2

GL_VENDOR     = Mesa/X.org

GL_EXTENSIONS = GL_EXTENSIONS = GL_ARB_multisample ..........

1489 frames in 5.0 seconds = 297.590 FPS

1573 frames in 5.0 seconds = 314.468 FPS

1643 frames in 5.0 seconds = 328.559 FPS

Not a huge issue anyway, any suggestions on a real fix is appreciated. I may download and re-install everything just for interests sake.

Desiderius · 04-22-2021, 02:00 AM

I cannot try with a new user since I have a long compilation I cannot interrupt.

But I have tested with "root" and it is the same problem.

Here is the result of "glxgears -info"

Code:

@netcrawl I cannot find your "work-around"!

Is it well in systemsettings ?

I have clicked randomly on the left side of the window but did not see this item.

Launching systemsettings5 by hand, I have seen with the "--list" parameter that it is possible to launch directly the options for a specific theme

But nothing here for "Iconic view" or "Sidebar view" !
