-GtkScrollbar-has-forward-stepper: 1;
-GtkRange-stepper-size: 13;
}*/
/*

quando inicio o gnome-shell com uma sessão guardada passado alguns dias o processo gnome-shell --sm-client-id 104c1d5139d66c06e915357041575668900000150450000 está a consumir perto de 30GB de RAM.

resolver:
desativar a gravação da sessão utilizando o dconfeditor:
org/gnome/gnome-session e desativar a opção auto-save-session

finalmente remover sessões guardadas:
rm -r /home/xana/.config/gnome-session/saved-session

cat /home/xana/.config/gnome-session/saved-session/org.gnome.Shell.desktop

numa consola diferente daquela que corre o ambiente gráfico:
XDG_SESSION_TYPE=x11 DISPLAY= gnome-shell --display :0 --replace&
