Hi Julien, I'm really sorry for the long delay, but I've finally managed to get a backtrace from gdb with this command: printf 'continue\nbt full\nquit\n' | nohup sudo gdb -p `pidof Xorg` The result are attached. Please tell me if you need anything else to debug this crash! Best regards Alexander Kurtz
