Problem: By default Debian with GDM3 is slow on older Hardware like Laptops or PCs with small Graphic Card
Background: GDM3 shows Images at size 800×600 an zooms up to Screen Size, this burns speed.
Solution:
edit gdm3-theme config
sudo nano /usr/share/gdm/greeter-config/20_debian
and change to
#Use a specific background #/desktop/gnome/background/picture_filename /..path #to wallpaper #/desktop/gnome/background/picture_options zoom #zoom /desktop/gnome/background/primary_color #357DAA # color Win2000
# Theming options #/desktop/gnome/interface/gtk_theme Clearlooks
# Greeter options #/apps/gdm/simple-greeter/logo_icon_name debian-swirl
# Play system beeps - especially the one when the greeter is ready #/desktop/gnome/sound/event_sounds true # Some other possible options #/apps/gdm/simple-greeter/banner_message_enable true #/apps/gdm/simple-greeter/banner_message_text Welcome #/apps/gdm/simple-greeter/disable_restart_buttons false #/apps/gdm/simple-greeter/disable_user_list false # The lower panel doesn't work with the compositor /apps/metacity/general/compositing_manager false # Prevent the power management icon from showing up /apps/gnome-power-manager/ui/icon_policy never
reboot and enjoy…
Additional Info:
- Install “metacity” window manager its needed by gdm3 too on openbox or LXDE Desktops
- If “desktop-base” is not installed the gdm3 background is shown lime green then create a empty file named
sudo nano /usr/share/gdm/greeter-config/10_desktop-base
