Enumeration Type Documentation

gp_linux_fb_flags

enum gp_linux_fb_flags

Linux framebuffer init flags.

Enumerator
GP_FB_INPUT_KBD	Use KBD to get input events. Does not support anything but very basic keyboard use GP_FB_INPUT_LINUX instead.
GP_FB_SHADOW	Use shadow framebuffer for drawing. Should be enabled unless you are on a very memory constrained hardware.
GP_FB_ALLOC_CON	Allocate new console, if not set current is used.
GP_FB_INPUT_LINUX	Use Linux input for keyboards and mouse. This is the modern alternative to KBD.
