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
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
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
