I did a default installation of Fedora 25 in qemu, using:

nice -n 19 ionice -c 3 qemu-kvm -machine pc-i440fx-2.4 -enable-kvm -global qxl.ram_size=1x1024 -m 2048M -smp 2 -drive file=./Fedora-Workstation-netinst-x86_64-25-1.3.iso.qcow2,index=0,media=disk,cache=unsafe -localtime -serial file:/tmp/qemu-Fedora-Workstation-netinst-x86_64-25-1.3.iso.qcow2-output.log -name Fedora-Workstation-netinst-x86_64-25-1.3.iso.qcow2 -cdrom /local/mfabian/iso/Fedora-25/Fedora-Workstation-netinst-x86_64-25-1.3.iso -boot c -spice port=6002,disable-ticketing,streaming-video=off -vga qxl -display vnc=:6 -net nic -net user,hostname=Fedora-Workstation-netinst-x86_64-25-1.3.iso.qcow2,hostfwd=tcp::5556-:22 -monitor stdio -usb -usbdevice mouse -soundhw all

After the installation, I added KDE using

    sudo dnf groupinstall kde-desktop-environment

Then I logged into KDE and started a konsole.

The konsole window had no titlebar.

See screenshot.

The usual reason for no title bars is that there is no window manager running, in this case, kwin.  Maybe it crashed.

Try krunner (alt-f2):  kwin_x11 --replace


and see if that helps?

[mfabian@Fedora-Workstation-netinst-x86_6 ~]$ ps aux | grep kwin
mfabian   3363  0.0  0.0 121212   944 pts/2    S+   07:40   0:00 grep --color=auto kwin
[mfabian@Fedora-Workstation-netinst-x86_6 ~]$

It does indeed not seem to be running.

I tried that, now there seems to be a kwin running:

[mfabian@Fedora-Workstation-netinst-x86_6 ~]$ ps aux | grep kwin
mfabian   3396  5.1  5.6 3549584 115660 pts/1  Tl   07:42   0:01 kwin_x11 --replace
mfabian   3411  0.0  0.0 121212   996 pts/2    S+   07:42   0:00 grep --color=auto kwin
[mfabian@Fedora-Workstation-netinst-x86_6 ~]$ 

But I still see not title bars and I cannot even type into konsole anymore and
the KDE menu at the lower left doesn’t work anymore.

After yet another "sudo dnf update" today, the problem disappeared.

Comment 5 Rex Dieter 2017-01-31 17:46:29 UTC
ok, thanks.  (guessing an odd bug in some other component, maybe video driver related)
