Neomagic MagicMedia256AV

Neomagic MagicMedia256AV This is a Neomagic video adapter Features Chipset: Neomagic NM2200 PCI ID: 10c8:0005 AGP 1X 2.5MB SGRAM

Linux X.Org driver

This chip is supported by the 'neomagic' driver as part of the X.Org distribution. Hardware acceleration is not supported at color depths above 16-bit.

The XVideo (xv) extension is supported in the driver. Xv problems in applications such as xine and mplayer may be helped by setting the "OverlayMem" option in the "Device" section of xorg.conf.

Option    "OverlayMem"    "829440"        # Sufficient memory for a full-screen DVD

ThinkPad LCD

Display on the internal LCD works as long as you set the monitor settings correct.

External VGA port

The external VGA port is known to work on at least X.org 1.3 and the kernel's NeoMagic VGA Framebuffer, both at 1024x768. It can be activated using the Fn+F7 button.

Warning: Avoid switching between the console and X11 with the external VGA port active. You might have to re-enable it or even be unable to until you reboot.

SVideo port

Works with VESA & mplayer

Linux kernel Framebuffer driver

I use the NeoMagic Framebuffer Driver in the Kernel 2.6.12rc5, since Kernel 2.6.8 with the following Configuration:

#
# Console display driver support
#
CONFIG_VGA_CONSOLE=y
CONFIG_DUMMY_CONSOLE=y
CONFIG_FRAMEBUFFER_CONSOLE=y
CONFIG_FONT_8x8=y
CONFIG_FONT_8x16=y   

# Graphics support
#
CONFIG_FB=y
CONFIG_FB_CFB_FILLRECT=y
CONFIG_FB_CFB_COPYAREA=y
CONFIG_FB_CFB_IMAGEBLIT=y
CONFIG_FB_SOFT_CURSOR=y  
CONFIG_FB_MODE_HELPERS=y
CONFIG_FB_VESA=y
CONFIG_VIDEO_SELECT=y
CONFIG_FB_NEOMAGIC=y
 

I normally use the 1024x768-16bit. It is good enough th play mplayer-videos oh this Framebuffer Device with the Option "-vo fbdev". If you use the devfs Filesystem, you must use the device /dev/fb/0 device.

the fb-settings are:

mode "1024x768-60"
   D: 65.003 MHz, H: 48.365 kHz, V: 60.006 Hz
   geometry 1024 768 1024 768 16
   timings 15384 160 24 29 3 136 6
   rgba 5/11,6/5,5/0,0/0
endmode
