Bug Description
Binary package hint: xserver-
Just upgraded my PC to natty as of today (alpha-3) and moved the HDD to a new PC barebone based on Intel Sandy-bridge (Core-i7 2600K) with two monitors connected.
After configureing xorg.conf and booting, kdm came up fine, but the session-type menu top-half is unreadable (garbled).
After logging in (Desktop effects disabled), everything seems to work for a few seconds with only minor display glitches, but after a random time, or at certain actions (like entering a URL in chrome), the X server freezes. Sometimes it freezes forever, and sometimes it comes back after a few seconds (display goes black for a while).
The system keeps running fine, and dmesg shows this:
...

In the situation shown above the X server had recovered from the freeze.

Extra information. Since today I have added
Option "Shadow" "true"
to the device section in xorg.conf and since that, the artifacts and visual glitches seem to be gone, and I have yet to see the X server freeze.
Of course this is not a solution, but merely a workaround. I have virtually no form of acceleration now.
