** 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.
