SMI LynxEM+

This is a Silicon Motion video adapter

Note: 4MB memory versions are called LynxEM4+ in IBM documentation

Features

  • Chipset: SM712G
  • PCI ID: 126f:0712
  • 2 or 4MB SGRAM
  • Interface: PCI 2.1

Linux X.Org driver

This chip is supported by the 'siliconmotion' driver as part of the X.Org distribution

ThinkPad LCD

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

External VGA port

?? where is the drivers for freebsd? X.org can not running in freebsd.(ibm240)

Blank Screen when exiting Xorg

If your screen doesn't go back to text mode (console) when you exit Xorg but instead your screen goes black, try adding the following line in the "Device" section of your xorg.conf:

  Option "UseBIOS" "false"

Linux kernel Framebuffer driver

There are two framebuffer drivers. One is sm712.c. The other is lynxfb.c. The sm712.c driver comes with the Embedded Linux Development Kit (eldk) as part of the stock Linux kernel and seems to work well (but possibly needs hardware-dependant tweaks in some embedded environments.) The second one, lynxfb.c was obtained directly from Silicon Motion and won't work without tweaks in some environments.

There is also limited framebuffer support for this chip in embedded devices as part of the "U-Boot" boot loader. This works well and is based on the second (lynxfb) driver.
