I have lightdm 1.26.0-7, lightdm-gtk-greeter 2.0.8-2, and xfce4 4.16 on Debian 11.6, on three machines. When I log in to an existing session, sometimes I get a snappy response and get the desktop quickly. Other times, there is a a delay, during which I have a black display with the pointer on it. The pointer responds to mouse movement. The delay has been anywhere from nearly instantaneous to several minutes.
I don't see anything obvious in /var/log/lightdm/*, but then again a lot of that is a mystery to me. Any ideas what's going on? -- Does anybody read signatures any more? https://charlescurley.com https://charlescurley.com/blog/
