My Ubuntu desktop crashes with segmantion fault after login. It is happening with every user and every desktop enviroment. The output of the command startx in tty2 is shown in the screenshots. And the output of cat/var/log/Xorg.1.log too. Its like that since a small update from ubuntu repros the last days,
