Title:
  10de:1057 "reduce brightness" key freezes system

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  When I have the Nvidia discrete graphics selected in the bios,
  pressing the "reduce brightness" key (blue fn + end), the system
  freezes. It doesn't matter if I'm in X or in text mode, it happens all
  the time.

  I did it while watching the logs (/var/log/syslog, ~/.xsession-errors)
  and even the debug console when in text mode (F8 iirc), but nothing
  was written there.

  The machine was also unreachable from the network after the fact.
