svgalib的helloworld

tasklist|findstr QQ

在32位的机器上只需要
apt-get install libsvga1*
其实就是
apt-get install libsvga1
apt-get install libsvga1-dev


yum install svgalib*

就喜欢大黑屏

gcc svgtest.c -lvga
需要修改
/etc/vga/libvga.config

fedora17没成功
回家试验ubuntu吧
apt-cache search vga
apt-get install libsvga1
apt-get install libsvga1-dev

# mouse_accel_type	normal	# No acceleration while delta is less then
				# threshold but delta is multiplied by
				# mouse_accel_mult if more. Originally done by
				# Mike Chapman [e-mail]

mouse_accel_type	power	# The acceleration factor is a power function
				# of delta until it reaches m_accel_mult. It
				# starts from the coordinate 
				# [1, 1 + m_accel_offset] and goes to
				# [m_accel_thresh, m_accel_mult]. If delta
				# is bigger then m_accel_thresh it is a plain
				# constant (m_accel_mult). It is the f(delta)
				# function with which the delta itself will be
				# multiplied. m_accel_offset is 1 by default,
				# so for delta = 1 the accelerated delta will
				# remain 1 (You don't lose resolution). The
				# starting point of the f(delta) function
				# might be moved along the Y axis up/down with
				# m_accel_offset thus defining the initial
				# minimum acceleration (for delta = 1).
				# Basically it's like the normal mode but the
				# acceleration factor grows as you move your
				# mouse faster and faster, not just turns in
				# and out. Threshold is the point from where
				# the f(delta) function gets linear.
				# This is the one I use for *uaking... =)

# mouse_accel_type	off	# No comment...


mouse_accel_mult	60	# This is the number with which delta will
				# be multiplied. Basically it's the number
				# that defines how big the acceleration will
				# be

mouse_accel_thresh	4	# This is the threshold. See description by
				# power

mouse_accel_power	0.8	# This is the second parameter of the power
				# function used in power mode. Used only by
				# the power mode

mouse_accel_offset	30	# This is the offset of the starting point
				# on the Y axis. With this you can define the
				# number that will multiply delta = 1 so it's
				# the initial acceleration.

# mouse_accel_maxdelta	600	# This is an upper limit for delta after
				# the acceleration was applied

# mouse_maxdelta	30	# This is an upper limit for the delta
				# before the acceleration. With this one you
				# can limit the biggest valid delta that
				# comes from the mouse.

# mouse_force			# Force parameters even if they seem strange
				# By default svgalib prints an error if any
				# of the numbers are somhow out of the
				# reasonable limit, (Like a negative mult :)
				# and uses the default that's in vgamouse.h

# The default device is /dev/input/mice.
# However, esp. with the Spacetec Spaceball you may
# want to specify a different device for svgalib to use

# mdev /dev/ttyS0 # mouse is at /dev/ttyS0

# Some multiprotocol mice will need one of the following:

# setRTS   # set the RTS wire.
# clearRTS # clear the RTS wire.
# leaveRTS # leave the RTS wire alone (default) (Wire is usually set)
# setDTR   # set the DTR wire.
# clearDTR # clear the DTR wire.
# leaveDTR # leave the DTR wire alone (default) (Wire is usually set)

# On mice such as the Microsoft IntelliMouse and Logitech MouseMan+, turning
# the wheel rotates the mouse around the X axis. mouse_wheel_steps controls
# how many steps make up a full 360-degree turn and thus how much rotation
# occurs with each step. The default is 18 steps (20 degrees per step), the
# real-world value for the IntelliMouse. Adjust it to match your mouse or to
# suit your preferences; a negative number reverses the direction and zero
# disables rotation.

mouse_wheel_steps 18		# For MS IntelliMouse (default)
# mouse_wheel_steps 24		# For Logitech FirstMouse+
# mouse_wheel_steps -18		# Reverses direction
# mouse_wheel_steps 0		# Disables rotation

# mouse_fake_kbd_event sends a fake keyboard event to the program when the
# wheel on a Microsoft IntelliMouse, Logitech MouseMan+, or similar wheel
# mouse is turned. This can be useful for programs that do not recognize the
# Z axis, but only works with some programs that use raw keyboard.
# The format is:
#
#   mouse_fake_kbd_event upscancode downscancode
#
# The up and down scancodes are the scancodes of the keys to simulate when
# the wheel is turned up and down, respectively.
#
# Scancodes can be specified numerically or symbolically; the symbolic names
# are determined by the keymap (see below), if no keymap is loaded the default
# is the standard US QWERTY keyboard with the following names available:
# letters (a-z), numbers (zero-nine), function keys (F1-F12), the keypad
# numbers (KP_0-KP_9) and other keys (KP_Multiply, KP_Subtract, KP_Add,
# KP_Period, KP_Enter, and KP_Divide), and the following - minus, equal,
# Delete, Tab, bracketleft, bracketright, Return, Control, semicolon,
# apostrophe, grave, Shift, backslash, comma, period, slash, Shift, Alt, space,
# Caps_Lock, Num_Lock, Scroll_Lock, Last_Console, less, Control_backslash,
# AltGr, Break, Find, Up, Prior, Left, Right, Select, Down, Next, Insert,
# and Remove.
#
# Note that this option has no effect unless the IntelliMouse or IMPS2 mouse
# type is used (see above). Also note that the simulated keypresses are
# instantaneous, so they cannot be used for functions that require a key to
# be held down for a certain length of time.

#  This example simulates a press of the left bracket ([) when the wheel is
#  turned up and a press of the right bracket (]) when the wheel is turned
#  down (good for selecting items in Quake II):
# mouse_fake_kbd_event bracketleft bracketright

# Keyboard config:

# kbd_keymap allows you to use an alternate keyboard layout with programs that
# use raw keyboard support by translating scancodes from the desired layout to
# their equivalents in the layout expected by the program. This option has no
# affect on programs that do not use raw keyboard.
#
# Keymap files to convert between any two arbitrary keyboard layouts can be
# generated with the svgakeymap utility, but there are limitations to the
# translations that can be performed. Read the file README.keymap in the
# svgalib documentation directory for more in-depth information.
#
# You must specify the full path to the keymap file; it is recommended that
# keymaps be kept in the same directory as libvga.config, normally /etc/vga.
# The keymap specified in the configuration file can be overriden by setting
# the environment variable SVGALIB_KEYMAP to point to another keymap file;
# this can be useful for setting keymaps on a per-program basis.
#
#  This example will use the provided US-Dvorak to US-QWERTY map to allow a
#  Dvorak keyboard layout to be used with a program that expects a standard US
#  QWERTY keyboard, for instance Quake:
# kbd_keymap /etc/vga/dvorak-us.keymap

# There is a potential security risk in allowing users to remap keyboard
# scancodes at will; with this option enabled only keymap files owned by
# root can be used. Normally you should leave this on, but if you have a
# single-user box or you really trust your users you may find it convenient
# to run without it and allow users to load arbitrary keymaps.

kbd_only_root_keymaps

# kbd_fake_mouse_event, as it says, sends a fake mouse event to the program.
# The format is: kbd_fake_mouse_event scancode [flag(s)] command [argument]
#   Scancode is a raw scancode or a descriptive name, the same as with fake
#   keyboard events (see above). If you use keymap conversion, specify
#   scancodes for the keyboard layout the program will receive.
#   Flags:   down   - trigger event when the key is pressed (default)
#	     up     - the opposite
#	     both   - trigger in both case, if pressed/released
#	     repeat - repeat events if the key is kept pressed (off by default)
#   commands: delta[xyz]  - send a fake delta event as if you have moved your
#	 		    mouse. If the parameter is 'off' / 'on' it will turn
#			    off/on the respective mouse axis (requires a
#			    parameter, of course)
#	      button[123] - send a fake event that the mouse button is pressed
#			    or released that's given by the parameter.
# 			    ('pressed' or 'released')
# Here are some examples:

#  This is one I use in *uake: it turns around, looks down a bit and when the
#  key is released it does the opposite, so it gets back to the starting state.
#  With this one and the help of a rocket you can fly though the whole map :)
#  (Scancode 28 is enter)
# kbd_fake_mouse_event 28 both deltax 8182 down deltay -1500 up deltay 1500

#  This one will switch off the y axis of the mouse while the key (right ctrl)
#  is kept pressed.
# kbd_fake_mouse_event 97 down deltay off  up deltay on

#  This one is the same as if you were pressing the left mouse button. (But
#  if you move your mouse then the button state will reset even if you keep
#  right ctrl down...)
# kbd_fake_mouse_event 97 down button1 pressed up button1 released

#
# These are prefered over the default timings (if monitor and chipset

# has its own syntax (see below).
# The format is identical to the one used by XFree86, but the label
# following the modeline keyword is ignored by svgalib.
#
# Here some examples:

# It seems there is a need for a 512x384 mode, this timing was donated

# Here's a 400x300 Modeline (created by svidtune). Note that for
# doublescan modes, the Vertical values are half the real one (so XFree86
# modelines can be used). 

# Modeline "400x300@72" 25.000 400 440 504 520 300 319 322 333 doublescan

# Here is a mode for a ZX Spectrum emulator:

# newmode 256 192 256 256 1

# the width must be divisible by 8. Some cards require even divisiblity by
# 16, so that's preferable, since there are no standard modes where the
# width is not divisible by 16.

# The following modes are defined in svgalib, but have no timings in
# timing.c, so you'll have to add a modeline in order to use them:
# 1280x720, 1360x768, 1800x1012, 1920x1080, 1920x1440, 2048x1152
# and 2048x1536   

# Mach32 timings:

# e.g. Setup a 320x200 mode for the mach32:

#define 320x200x32K 320x200x64K 320x200x16M 320x200x16M32

# Here are miscellaneous options to help with specific problems.

# VesaText	      # Helps the VESA driver with text mode restoration
		      # problems.

# VesaSave 14	      # changing value might help text mode restoring
		      # problems with VESA driver. Legal values: 0-15

# NoVCControl	      # Disables svgalib's finding a new VC if run
		      # from X. Good fo using dumpreg under X, but
		      # probably bad for standard usage.


# RageDoubleClock     # If your card is based on ATI's rage card, and
		      # the pixel clock is double what it should be 
		      # (main symptom is some modes are out of sync),
		      # try enabling this. If it helps, please report to
		      # me ([e-mail]) 

# NeoMagicLibretto100
		      # Enable if you have a NeoMagic card on a Toshiba
		      # Libretto 100, 110, etc
