ATI Mobility Radeon X1400

This is an ATI video adapter.


  • Chipset: ATI M54
  • PCI ID: 1002:7145
  • PCI Express x16
  • 128MB GDDR1 video memory
  • Up to 512Mb HyperMemory - ATI's name for their GPUs that utilise shared and dedicated memory.

Linux X.Org driver

Not Supported

ThinkPad LCD

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

External VGA port

Works, but only if the X-server detects something plugged in here, eg. before X started or after a restart.

SVideo port


DVI port


Proprietary ATI driver

Proprietary fglrx driver version 8.24.8 adds support for the x1400 chipset (according to ATI changelog). It works, including dualhead, 3d and video (XV) acceleration, when using the fglrx kernel module. (Without it, you get screen corruption including underlined mouse pointers.)

Sample "Device" section for xorg.conf:

Section "Device"
       Identifier  "ATI Graphics Adapter 0"
       Driver      "fglrx"
       Option      "ForceMonitors" "lvds,crt1"
       Option      "Centermode" "off"
       Option      "VideoOverlay" "on"
       Option      "OpenGLOverlay" "off"
       Option      "OverlayOnCRTC2" "0"
       Option      "PseudoColorVisuals" "off"
       Option      "HSync2" "31-64"
       Option      "VRefresh2" "56-75"
       Option      "UseFastTLS" "off"
       Option      "Mode2" "1280x1024,1024x768,800x600,640x480"
       BusID       "PCI:1:0:0"

The kernel module doesn't work out of the box with the 2.6.16 kernel, you get undefined symbols such as module_get_request when inserting the module. The following patch to firegl_public.c fixes it (from ):

XVideo support using the VideoOverlay option may not work with recent drivers. With version 8.29.6 of the fglrx driver, you can instead use

       Option          "TexturedVideo" "on"

Use the xvinfo utility to verify if XVideo support is available.

Linux kernel Framebuffer driver

Works with the VESA driver at 1280x1024 (you have to append vga=794 to the kernel boot parameters)
