Everyone:
Ever since the latest massive kde5 update (Saturday 8 May
2021), I have not been able to use the task bar to switch
between open windows - and sometimes not even to start
certain applications that have taskbar icons. Anything in the
System Tray is all right - like the dnfdragora update icon,
the clipboard, the new-device icon, or the volume icon. But
anything for an open window? Forget it. Every time I click on
such an object, the computer pauses for about ten or fifteen
seconds, during which it accepts no input from mouse or
keyboard - and then blanks the screen, abruptly closes all
open windows, and restarts the session. Most of the time the
session is all right, but not always - in which case I
restart the machine.
It's not the kernel. I've tried this with all three versions
of the kernel I now have on board. (They're all three F34
builds by now.)
It's one or more of the applications that are part of KDE
Plasma. But I despair of telling which one. That update had
185 programs in it, and only four of them are referable to
the kernel.
I can always use the Alt-Tab trick to browse open windows to
get to any open window I want. I can always start most
programs through the Applications Menu; that icon works. I
/think/ I can start one instance of Dolphin - but starting a
new instance requires the task bar, so that's out. The only
way to open two instances of Dolphin is to connect an
external device, thus giving me an excuse to open that device
in Dolphin and then switch views. (And another thing:
movement and copying from one Dolphin instance to another is
also broken. I have to use the clipboard as an intermediate
step. Otherwise Dolphin complains that it /can't read/ what
I'm trying to move or copy.)
In other news, my bug reporting system is broken and won't
report anything, and the KDE Daemon keeps crashing at the
beginning of every session - though I can't tell whether I'm
losing anything by that.
Has anyone else noticed this issue?
Can someone having an intact reporting system, or an upstream
channel, try to report this?
I wonder if the update didn't fully complete? Does this show
any plasma/kf5 related updates?
yum list updates
No. No updates available at this time, from any repository.
Whatever packages I got, the update went through. Ergo, I
didn't get every package that needed to change, or the latest
Plasma/KF5 update contains a bug or bugs related to the Task Bar.
Are yum running plasma under Wayland or X11 ?
As far as I know, I'm using X11. I don't remember explicitly
transferring to Wayland. I have been upgrading by the command
line for every iteration since F21 at least, and so I should
always have kept the same interface, which should be X11. I
wouldn't know how to transfer to Wayland; I'm not even sure
whether that is a valid interface for desktop hardware.
Default in Fedora 34 is wayland. Do this in Konsole and see if
there is any kwin/plasma stuff that comes back:
ps ax|grep wayland
Done, and here is the output:
ps ax|grep wayland

The word "wayland" appears in red; the rest of the above text
appears in white.
Does that confirm your suspicion?
Yes. Try selecting an X11 plasma session from the SDDM login screen.
And how do I get to that point? My login screen asks me only one
thing: who am I, among three registered users of this computer? It
does not ask me for a preference of X11 v. Weyland.
Should be in the bottom left as a pulldown. I don't find it very
prominent.
Problem solved. X11 restored certain behaviors to which I was
accustomed. (Wayland, for instance, insists on opening all popups in the
nearest corner instead of in the middle of the screen.)
So I can attest: Wayland is not for everyone. Certain equipment requires
X11.
