Check if you already have the cursors you need before installing any new package. Cursors can be found in the /usr/share/cursors directory.
x11-themes/xcursor-themes comes with the whiteglass and the redglass themes:
emerge --ask x11-themes/xcursor-themes
Another package with some Gentoo themed cursors is available as well
x11-themes/gentoo-xcursors comes with gentoo, gentoo-blue, and gentoo-silver cursor themes:
emerge --ask x11-themes/gentoo-xcursors
To install all of the cursor themes available from Portage:
emerge --ask x11-themes/blueglass-xcursors x11-themes/chameleon-xcursors x11-themes/comix-xcursors x11-themes/gentoo-xcursors x11-themes/golden-xcursors x11-themes/haematite-xcursors x11-themes/neutral-xcursors x11-themes/obsidian-xcursors x11-themes/pearlgrey-xcursors x11-themes/silver-xcursors x11-themes/vanilla-dmz-aa-xcursors x11-themes/vanilla-dmz-xcursors x11-themes/xcursor-themes
Edit your ~/.Xresources file:
Cursor size can be optionally chosen as well:
Cursor keeps going back to default X cursors
In some desktop environments the mouse theme can change when hovering outside of a window. Inside the window the mouse cursor respects the user's choice. But outside the window the mouse cursor changes into the default X cursor.
Create the symlink to your home path.
ln -s /usr/share/cursors/xorg-x11 ~/.icons
GTK+ 2 and GTK+ 3
With some GTK+ applications the mouse cursor changes to default settings when the it is inside the GTK+ application window. Users can fix this problem by setting the gtk-theme-name and gtk-cursor-theme-name variables in ~/.config/gtk-3.0/settings.ini and ~/.gtkrc-2.0. In the examples below the
gentoo cursor theme as been chosen.
For GTK+ 3 applications:
[Settings] gtk-theme-name = gentoo gtk-icon-theme-name = gnome gtk-cursor-theme-name = gentoo
For GTK+ 2 applications:
gtk-theme-name = gentoo gtk-icon-theme-name = gnome gtk-cursor-theme-name = gentoo
