Description Tony Su 2018-02-11 23:31:14 UTC
Have tested with both the fvwm2 and awesome Window Managers.

No matter what is configured with

update-alternatives --config default-xsession.desktop

On next boot, the currently configured window manager persists.

Only by disabling auto-login and then selecting the window manager in the sddm login screen can you change the window manager, and then that setting persists until it's changed in the sddm login window again (no alternatives setting works, ever). 

Did not test whether the window manager appearing as an sddm login option is because of an alternatives configuration or if exists in /etc/alternatives/, the latter can exist without the former.

TW version isn't likely relevant but is seen on the current image 20180129

That's how sddm's configuration works.

sddm stores the last window manager in /var/lib/sddm/state.conf.

default-xsession is only used:

- The first time sddm is started
- As default autologin session (unless you configure a different one in the sddm configuration)

Works as intended - if do not think this is the case, please reopen.
