This is an ATI video adapter

Features

  • Chipset: ATI M6, ATI RV100 series
  • PCI ID: 1002:4c59
  • AGP 4X
  • 8, 16 or 32(maximum) mebibyte DDR-SDRAM video memory
  • External VGA up to: 2048x1536x16.7M at 75Hz

Also known (in IBM literature) as....

  • ATI Mobility RADEON
  • ATI Rage Mobility RADEON M6
  • ATI Rage Mobility RADEON M6MC
  • ATI Mobility RADEON M6C (eg. M6C-16h)
  • ATI Mobility RADEON M6 LY

Linux driver - OpenSource

This adapter is supported by recent versions of the radeon driver as found in X.Org.

Optimal xorg.conf settings

This is the currently best working Device section for the xorg.conf of an X31 running Kubuntu 9.04 (X11R7.4):

Section "Device"
       Identifier      "ATI"
       Driver          "radeon"
       Option          "AccelMethod" "XAA"
       Option          "AGPMode" "4"
       Option          "AGPFastWrite" "yes"
       Option          "EnablePageFlip" "on"
       Option          "RenderAccel" "on"
       Option          "DynamicClocks" "on"
       Option          "BIOSHotkeys" "on"
EndSection

By far the most important setting here is "AccelMethod" "XAA", which dramatically improved graphics performance for Compiz and related desktop effects, while eliminating certain graphics errors. The other settings combined provided an improved glxgears performance of about 20% while not affecting Desktop performance much.

ThinkPad LCD

The ThinkPad LCD (LVDS connected) properties should be automatically detected and properly configured with any recent Xorg version.

External VGA port

Works fine with xorg radeon driver.

SVideo port

The SVideo port should be supported by the current Xorg radeon driver.

Please read How to get TV-Out working on ATI graphic cards on how to set it up.

Linux driver - Proprietary

This chip is not supported by the proprietary ATI driver

Linux kernel Framebuffer driver

  • Tested and working fine under Gentoo.
  • Tested and working under Debian Etch.
  • Tested and working under Debian (with re-compiled kernel 2.6.16-9).

Linux Kernel Mode Setting (KMS)

Tested and works with Fedora 11 on a X22. But only for the ThinPad LCD (LVDS), external VGA does not work.

Problems (and Solutions)

Problem with video output switching

On some models there are problems with video output switching and the xorg radeon driver.

Xorg & OpenGL

See http://forums.gentoo.org/viewtopic-t-451151-highlight-.html for information on how to enable stable OpenGL support. Some of the tricks are:

  • disable the console frame buffer.
  • disable the hardware cursor in Xorg.
  • plus some more.

NOTE: Default Dpi 16 bit for card Ati Mobility Radeon M6 LY

NOTE: I (User:msoos) actually got DRI direct rendering with framebuffer and hardware cursor, without any fancy setting at all (apart from re-compiling the 2.6.16-9 with some more-or-less standard setting) on Debian testing.

I (User:ungoliant) confirm what msoos said. DRI is working wonderfully with framebuffer and hardware cursor. AIGLX is working too, albeit a bit slow ( Compiz or Beryl are not as snappy as the 2D desktop is ). Debian Etch, and kernel 2.6.20.

The settings made with DRIconf can have a huge impact in 3D performance. Please take a look at DRI options for ATI Radeon.
