** Summary changed:

- [GMA X4500HD] Periodically freezes system when X11 is (re-)initialized
+ [GMA X4500HD] Video mode changes freeze system

** Description changed:

  Binary package hint: xserver-xorg-video-intel
  
- On  average every second X11 startup freezes my Dell Vostro 220s with
- GMA X4500HD.  The screen goes blank and the system is completely frozen.
- Changing to a text console with Strg-Alt-F1 or killing the server with
- Ctrl-Alt-Backspace does not work. A mouse pointer is not shown. The
- keyboard leds are not changing when pressing Caps or NumLock. I can not
- ssh into the system since apparently it does not even have time to
- request an IP address from the DHCP server before it freezes. A soft
- power down does not work either, the only way to shut down the computer
- is to press the power button for several seconds.
+ On  average every second video mode change completely freezes my system.
+ The screen just stays blank and the system is completely unresponsive.
+ The keyboard leds are not changing when pressing Caps or NumLock and ssh
+ access into the system times out. A soft power down does not work
+ either, the only way to shut down the computer is to press the power
+ button for several seconds.
  
- This habens both for normal startups and for resume from hibernation.
- Quitting usplash and changing to text mode with Alt-F1 during boot does
- not prevent the problem.
+ The behaviour can be triggered by starting X11, resuming from
+ hibernation, switching to a text console, or switching to a different
+ user in X11.
  
- Although it does not happen on every boot, the problem tends to stick
- for a while once it is there:  I usually get around 3 crashes in a row
- before I can boot properly again.
- 
- I'm using Intrepid.
+ I'm using Intrepid on a Dell Vostro 220s with GMA X4500HD onboard
+ graphics.
