Bug#795471: bug 795471 : workaround

[pc <p.c79@orange.fr>]

I have found this possibility :

Is ther is no config file of SDDM (On systems controlled by systemd 
<https://wiki.archlinux.org/index.php/Systemd>, everything should work 
out of the box, since SDDM defaults to using |systemd-logind| for 
session management. The configuration file will therefore not be created 
at package installation time), SDDM offers a command for generating a 
sample configuration file with the default settings if you really want one:

# sddm --example-config > /etc/sddm.conf

After that, you can modify the config file /etc/sddm.conf :

# Default $PATH
DefaultPath=/bin:/usr/bin:/usr/local/bin

like this :

# Default $PATH
DefaultPath=/bin:/usr/bin:/usr/local/bin:/usr/games

and the path is ok after closing and opening the session

You can also modify many other option.

For information, I have found this here :https://wiki.archlinux.org/index.php/SDDM#Theme_settings
