Thanks Santa.

Though there was a slight problem. After the du all I didn't even reach a login screen merely a black screen. A reboot was no help.

journalct -b -p err told me that sddm-greeter couldn't find the Qt platform "xcb". It also went on to list the available plugins but the list didn't contain anything relating to xcb.

Using apt-cache I found the plugin libqt5cxbqpa5 was available. After installing it and rebooting I reached the login screen and finally to the desktop.

I don't know why libqt5xcbqpa5 was missing but the above solution might help someone else.

Thank you for posting this, gnome user here and I was getting this error in vlc, where the qt platform plugin xcb was missing.  Installing libqt5xcbqpa5 fixed it.

To all that expressed their thanks:

I'm glad my solution was helpful. I guess that's what we're here for: to help one another when we can.

I had the same problem as you and your solution fixed it. How did you know that libqt5xcbqpa5 was missing?

I did an apt-file search for libqxcb and it seems to belong to libqt5gui5, but libqt5xcbqpa5 "Replaces lilbqt5gui5 (<< 5.5.0+dfsg-1~)"
How were you able to work out that libqt5xcbqpa5 replaces libqxcb?

 
Code: [Select]
apt-cache policy libqt5gui5
libqt5gui5:
  Installed: 5.5.1+dfsg-2
  Candidate: 5.5.1+dfsg-2
  Version table:
 *** 5.5.1+dfsg-2 0
        500 http://http.debian.net/debian/ unstable/main amd64 Packages
        100 /var/lib/dpkg/status
     5.5.0+dfsg-1~siduction1 0
        500 http://packages.siduction.org/kdenext/ kde-frameworks/main amd64 Packages


Does it mean that it is safe now or will something break again?


Does the report that libqt5cxbqpa5 "Replaces libqt5gui5 (<< 5.5.0+dfsg-1~)" mean that a libqxcb is not ready yet for libqt5gui5 >> 5.5.0+dfsg-1

I have got a new problem now. Vlc videos are now black from about an inch downwards. If the screen is resized the hoorizontal part resizes and the image retains the correct aspect ratio, but it is all black from an inch downwards. on 1920x1080 24 inch screen

For me the posting of the day. I ran into the same problem this morning and was totally clueless. Thank you very much.

I have a similar issue ... but much worse, if I run cvlc and the file name its fine from command line.  It must be a QT issue.

I didn't know for certain but..

According to my rough notes (I always try to keep notes) journalctl -b -p err provided the following lines
Code: [Select]
sddm-greeter[1130] This application failed to start because it could not find or load the Qt platform "xcb"
Available platform plugins are: linuxfb, minimal, mimimaleg1, offdcreen
reinstalling the application may fix the problem

This suggested there was a missing a Qt5 plugin for xcb. A simple search threw up libqt5xcbqpa5. Although it didn't appear in the sddm dependencies it seemed to be a "good fit". Also the Qt5 transition could be throwing up all sorts of errors.

This is debian unstable and sometimes one has to take an educated guess. So I installed libqt5xcbqpa5.

I'm just checking back since the gcc5 transition and getting overwhelmed with all the threads, especially the negative one.  If I read it right it seems the qt5 transition means I still shouldn't du.  Could someone please verify for me if this looks ok. 

I have kdenext, on firestarter my last du was in July after upgrading to Plasma5. Everything has been working great, I've just not performed du in forever. This is what du wants to do: does it look safe?  The problem I recognize as needing are gimp, inkscape, gtk3-engines-oxygen. I don't see how gimp and inkscape relate to qt5.

PS, I saw some unwarranted negativity about the optional kdenext and saw a reference to Santa leaving.  Please I hope that's not true.  Santa's work is amazing and keeps us having a modern and polished KDE. For those that want it, pure Debian KDE is always an option.

Just for the sake of curiosity: Santa, is your valuable debugging work done on kdenext also being somehow upstreamed to debian sid?
