I'm trying to customize my login manager in Linux Mint 18.3 Xfce
As you can see on the screenshot of a standard default mint config, the login dialog is located on the left side of the screen, and I would like to place it at the center (the red rectangle in screenshot)
There are some default lightdm config files in
/etc/lightdm, standard mint greeter config is located in
and specific customization, which actually overrides parameters in parent files is located in
Code: Select all
[greeter] background=/usr/share/backgrounds/linuxmint/default_background.jpg theme-name=Mint-X icon-theme-name=Mint-X font-name=Ubuntu 11 xft-antialias=true xft-dpi=96 xft-hintstyle=hintslight xft-rgba=rgb indicators=~host;~spacer;~clock;~spacer;~session;~a11y;~language;~power keyboard=onboard reader=orca position = 50%,center 50%,center default-user-image = #avatar-default screensaver-timeout = 60 a11y-states=contrast;font;keyboard;reader user-background = false clock-format = %a %d %b, %H:%M
I read somewhere that parameter for login dialog is
Code: Select all
[Greeter] draw-user-backgrounds=false draw-grid=true theme-name=Arc-Darker-Solid icon-theme-name=Papirus background=/usr/share/backgrounds/linuxmint/default_background.jpg
position, but changing
positionparameter either in
slick-greeter.conf, or in
/etc/lightdm/lightdm-gtk-greeter.conf.d/99_linuxmint.conf, doesn't seem to influence actual position of dialog box (nothing changes !).
On the other hand, if I change some parameters in
draw-grid=falsefor instance, then I can see that grid has disappeared in lightdm as soon as I lock my session.
So question is : how to move login dialog in the center of the screen in login manager in Linux Mint 18.3 Xfce ?
