** Description changed:

  I have just installed 8.10 on a new machine that has a Intel 3100
  graphics and Samsung 205BW monitor (lspci attached).  Sometimes I can
  get to login screen and the graphics are perfect, but most of the time
  the screen just blanks out.  I can still login 'in the dark' because I
  hear the ubuntu login prompt but even if I do, it remains blank.
  Interestingly, when selecting between boot options between kernel
  versions 2.6.27.11 and 2.6.27.7,  the earlier kernel seemed to work
  slightly better in that I get a display more regularly (say 40% I get
  display at login compared to say 10%).  With a different monitors I have
  no problem.  Clearly the monitor may be root cause, but as a Chartered
  Engineer, I would call this a bug in either the  kernel or Xorg because
  of the intermittent nature - sometimes I get a display other-times not.
  Note once I am in, there is no problem with display and everything works
  fine in maximum resolution.  Also, when booting after GRUB, the display
  is always perfect (i.e. whilst watch the progress bar) - its just before
  and when you get to login stage.
  
  I have researched this problem extensively and made changes to my
  Xorg.conf as a result to provide explicit info to X regarding necessary
  205BW resolution, hsync, vsync settings etc (file attached) since some
  forums suggest the problem lies with incorrect ESID from the 205BW.
  However, it still does not work properly.  I have even installed the
  latest Ubuntu alpha 6 release (jaunty) but again I have the same
  problem.  Even changing Xorg.conf file from default, whilst it seemed to
  work a few times, at the last login it failed again so I am back to a
  very frustrating problem - please don't make me buy a new monitor! -
  Thanks.
