** Description changed:

  "Check disc for defects" (run on a different computer than the test system) reports no errors.
  
  I booted from a CD, chose English, and selected "Try Kubuntu without
  installing".  After ~10 seconds the screen flashed on and off
  repeatedly, then stayed in the black-but-powered-on state.  Eventually I
  heard the KDE start-up sound.  The screen did not light up when I tried
  moving the cursor or pressing keys.  Ctrl-Alt-F1 and Ctrl-Alt-F7 did not
  switch to other TTYs or sessions.
  
  The test computer is an HP Elitebook 8440p model WH255UT#ABA. Chipset:
  Mobile Intel QM57 Express, graphics: Intel Graphics Media Accelerator
  HD.
  
  Note especially that this computer _does_ boot up successfully with a
  year-old Xubuntu 9.10 Live CD.
