Since downgrading the xorg fixes it, then surely that makes it an xorg issue? Since a lot of applications are giving the same unhandled signal error then it has to be a common library or something else in common so again that points to the xorg.

I installed the display manager "slim". It started and I could login. But I have the same errors with the MATE desktop like on QEMU. Some colors are wrong on the ubuntu MATE desktop. I can't use the mate-panel. If I click on the panel (menu, icons etc) then nothing happens. The mate panel and the mate taskbar starts again and again. And there is a blank error message in the middle of the desktop. I installed lightdm again and I downgraded the Xorg packages again. Everything works without any problems again.
