I'm testing on HP 7600U (945) and HP 7700U (965) running FC4 with 2.6.20 kernel and Xorg 7.2 + tar balls depends to support git intel driver built from source. 1. start Xorg 2. xmessage Hello 3. ^C xmessage 4. xmessage Hello At 1 the screen goes black showing Xorg is running and the screen is happy. At 2 Hello appears on the screen At 3 the Xorg server resets and the screen is still happy. At 4 the screen sees the VGA signal go away. Since xmessage is the one and only client when it quits the Xorg server will reset itself. The interesting message in the logs is: (WW) intel(0): Hardware claims plane A is off while software believes it is on
It's simpler then I thought. Only three steps (I did not wait log enough to see the screen notice the VGA signal had gone). 1. start Xorg 2. xmessage Hello 3. ^C xmessage At 1 the screen goes black showing Xorg is running and the screen is happy. At 2 Hello appears on the screen At 3 the Xorg server resets and the screen sees the VGA signal go away.
