Information about the problem of system lockups with the ATI driver.

Problem description

A few minutes after starting X windows the system locks up hard.

Affected Models

  • ThinkPad T42
  • ThinkPad T41p
  • other ThinkPads with a FireGL chipset and possibly other ATI chipsets

Affected Operating Systems

  • Xorg 6.9.x


The problem has been fixed in 7.0. However, some Linux distributions still release 6.9.x as their current version.


The easiest solution is to switch to the "vesa" driver in xorg.conf.

You can also downgrade to 6.9.x or upgrade to 7.0. Debian users can get 6.9.x packages from [1].
