Public bug reported:

Binary package hint: xserver-xorg-video-intel

I'm running Karmic, 9.10, on a Sony Vaio VGN-C260E laptop, using an
Intel driver (see lspci output below).  My computer is completely
freezing under two circumstances:

1.  I connect an external monitor after the laptop is already booted up

2.  If I boot the laptop with an external monitor attached, it works
properly (output is to external monitor, not to laptop display).
However, if I  attempt to switch between the external monitor and laptop
display using the Fn-F7 hotkey, it will switch to displaying on both
displays.  If I hit Fn-F7 again the laptop freezes.  No
ctrl+alt+backspace/esc/delete/Fxx does anything.  I have to hard power
down

Note -- if I properly turn off the external monitor (using system-
preferences-display), I can disconnect it just fine and use the laptop
display.  If I then attempt to plug in a DIFFERENT external monitor, I
get the same behavior as in 1.

>From reading around, it looks as though this is related to the xserver-
xorg-video-intel package, and that people have had similar experiences.
I list this as a new bug because it seems I'm having slightly different
behavior, and with different hardware.
