** Description changed:

  Binary package hint: xserver-xorg-video-intel
  
  When the KDE panel auto-hide feature is enabled and aMSN Messenger is
  started, if I move the pointer to the bottom of the screen several times
  (where the hidden panel is supposed to be), X will crash. Usually, X
  will not crash the first time I move the pointer to the bottom of the
  screen (instead, it will show the panel as it's supposed to do) and it
  does not take an exact number of pointer moves : it seems to take from 2
  to 10 pointer moves to show the panel before X will crash. I didn't
  count the exact number before each crash but I realized it changes from
  one time to another.
  
  I realized that I have the same bug if I use another non-KDE application
  that adds an icon to the system tray (I had the same bug after starting
  Skype).
  
  If I enable KDE panel auto-hide but I don't start an application that
  adds an icon to the systray, X won't crash (no matter how many times I
  move the pointer to the bottom of the screen to show the panel). If I
  disable auto-hide (set the panel to "Always visible") and I start aMSN
  or Skype, X won't crash.
  
  I have never experienced this bug when I use GNOME (I have both GNOME
  and KDE installed on my Ubuntu 10.04)
  
  After a crash, I see the dialog when I have an option to run Ubuntu in
  low graphics mode. I'm still able to use ttys (Ctrl+Alt+F[1-7]). If I
  don't choose "run Ubuntu in low graphics mode" and I try to log in as
  root in text mode and then run startx, X won't start. If I choose to run
  Ubuntu in low-graphics mode, I can open a KDE or a GNOME session again
  and I still have a 1280x800 resolution (the same as in the 'normal'
  mode.
