Thanks for the idea. In fact, there is a bug with xorg-server-1.20.0 and the "compositor" of Xfce. See this bug report and message: https://lists.debian.org/debian-user/2018/05/msg01008.html https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=900550 For the ones affected, if X doesn't start, you have to downgrade xserver-xorg-core and xserver-org-video-nouveau (apt install xserver-xorg-core/testing xserver-xorg-video-nouveau/testing), then you can start X and uncheck the compositor activation check in Xfce. After that, you can upgrade back the package and reboot. Pétùr
