Geeqie for Debian ----------------- It has been reported that geeqie has problems when using the XInput extension (which it does by default), and this special handling can be disabled by using the GDK_CORE_DEVICE_EVENT environment variable. Simply start geeqie with GDK_CORE_DEVICE_EVENT=1 geeqie to try this out. For GTK+ documentation about this environment variable, please see https://docs.gtk.org/gtk3/x11.html
