Hi there,
I'm using deepin for my desktop all day work. But since yesterday (2017-08-18) the X desktop does not startup anymore. I just get the blinking cursor after grub.
After three hours of unsuccessfull searching, I know hope for support from you. Now I'm running on a very broken desktop environment. I switched the lightdm greeter to gtk, because I found the following output in /var/log/lightdm/seat0-greeter.log. This helps to start X again, but the deepin desktop and deepin applications segfault if launched. Additionally, the background-image is missing and the ui is horrible.
info: "HDMI2 connected 1920x1080+0+0 (normal left inverted right x axis y axis) 950mm x 540mm"
found monitor: "HDMI2"
enable monitor true ""
This application failed to start because it could not find or load the Qt platform plugin "xcb"
in "".
Reinstalling the application may fix this problem.
Copy the Code
Directly following this suggestion, I reinstalled 'dde' recursive with its dependents following https://askubuntu.com/questions/275719/reinstall-package-and-its-installed-dependencies - this DIDN'T solve the problem
In addition to the greeter problem, the lightdm reports in '/var/log/lightdm/lightdm.log':
Then I digged into it more deeply. The problem seems to be the QT plugin xcb which binds Xorg and QT. The main reason for this error is missing, corrupt or unresolved 'libqxcb.so' I tried using ldd on the lib, strace and some friends but it seems, that the library is not the problem.
After this I tried to set the environment variable 'QT_QPA_PLATFORM=' and 'QT_DEBUG_PLUGIN=1' hoping for more information about the problem, but it also didn't solve the problem.
The last thing I did in my last session, that I can remember of is, that I installed some software: inkscape, gimp, unzip, qlandkartegt (removed again), darktable (removed again), rawtherapee
Can you help me with the problem? I can't figure out how I should solve this issue by myselve...

Oh thanks for your responses. This is the output for ldd /usr/bin/dde-dock:
I also rebooted the system as grubconfigure was initiated. but this didn't help either. So I still hope for the ldd to bring the solution...

As the deskop can't be used in the state it is right now, I will hardly have to switch to an other distro.
The Look & Feel was quite amazing with deepin, but I need a stable desktop UI. But please stay with your project...
