Hi! I was suspecting that all this was caused because the session is stablished by /usr/share/wayland-sessions/xfce-wayland.desktop executing like this: Exec=startxfce4 --wayland
Which means that it rins startxfce4 with an argument, it looked to me that lightdm is trying to exec "startxfce4 --wayland" altogether. So I did this test, copy xfce-wayland.desktop as xfce-way.desktop and modify it so that it now reads: Exec=startxfce4way End wrote a small script /usr/local/bin/startxfce4way which reads: #!/bin/bash exec startxfce4 --wayland $@ With this hack on lightdm runs the wayland session without any problem. I wonder if this can be fixed on lightdm or if it would be better to assign it to xfce4 and have it fixed there. Regards... -- Manty/BestiaTester -> http://manty.net
