Rüdiger Kupper, regarding your LTSP setup, in order for any of the
issues you brought up to be addressed, it would be best to file one
report, per problem, per hardware combination (ex. graphics lock up at
unpredictable times would be a good start).

Title:
  Intel driver reports hung GPU und disables acceleration

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  Hardware info: product: 82845G/GL[Brookdale-G]/GE Chipset Integrated
  Graphics Device

  I get no 3d acceleration with the intel driver. Cheking the logs I see that the driver reproducibly reports a hung GPU and disables acceleration.
  The log file asks me to get the output of dmes and the debugfs error_state file, which I attach below.
  This is not a random lockup, which is often reported, but it happens *every time*.

  In addition, I randomly experience X freezes, even with acceleration
  disabled.
