Trident Cyber9397DVD

This is a Trident video adapter


  • Chipset: Trident Image
  • PCI ID: 1023:939a
  • Interface: AGP 1X
  • 4 or 8MB SGRAM

Linux X.Org driver

This chip is supported by the 'trident' driver as part of the X.Org distribution. Man page for driver

ThinkPad LCD

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

External VGA port

Works, although can be somewhat temperamental with X (can require switching to console/back to restore sensible behaviour). I have been told (second-hand) that the X people are not going to develop support for using the VGA port in multi-head mode, like Windows 98 can. Please correct me if I'm wrong.

TV Out port

Available only on machines with the optional DVD and Enhanced Video Adapter (DEVA) installed.

Only works at 800x600 or lower. When using APM, TV out is switchable using tpctl. Should be switchable using the acpi video module, but I don't think it works. Alternatively can switch to TV before booting linux.

Linux kernel Framebuffer driver

  • vesafb: Works fine
  • vesafb-tng: Works, but does not get the start address of the framebuffer correctly. With a nasty obvious hack, it works (author not informed yet---will update if there is any progress)
  • tridentfb: Last time tried display syncs, but lots of garbage on screen and scrolling accelleration doesn't work. Incompatible with X.
