This is an ATI video adapter


  • Chipset: ATI RV200 (variant of the R100 core)
  • PCI ID: 1002:4c57
  • AGP 4X
  • 16 or 32MB DDR-SDRAM video memory
  • External VGA up to: 2048x1536x16.7M at 75Hz

Linux driver - OpenSource

This adapter is supported by recent versions of the radeon driver as found in X.Org and XFree86. It also works with the 'ati' driver. It does not work with the fglrx binary driver.

ThinkPad LCD

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

External VGA port

Works fine with open-source drivers. It turns on automatically when an external display is present. It can also be used for dualhead with Xinerama (with different resolutions on both screens) or MergedFB.

SVideo port

SVideo out is supported by the ati.2 driver from the GATOS project.
Read here how to set it up.

DVI port


3D Acceleration

Initially, ATI did not produce Radeon drivers for Linux, instead giving hardware specifications and documentation to Direct Rendering Infrastructure (DRI) developers under various non-disclosure agreements. The proprietary Linux drivers don't support the R100 chips (Radeon 7000-7500).

As of 2006.09, with Debian Sid (X Window System Version 7.0.0) i have 3D acceleration, without any proprietary or GATOS driver. Kernel version is

OpenGL vendor string: Tungsten Graphics, Inc.
OpenGL renderer string: Mesa DRI Radeon 20060327 AGP 1x TCL
OpenGL version string: 1.3 Mesa 6.5.1

It is reported that 3D Acceleration works fine with DRI driver under Fedora Core distribution, with the configuration similar to R300.

Linux driver - proprietary

ATi's proprietary Linux drivers support only the R200/FireGL graphics chips and above. The Mobility Radeon 7500 is based on the R100 graphics chip; the only Linux driver available for this chip is the open-source radeon DRI.
