X-Server rebooting when closing laptop-lid

[Roger Grosswiler]

Hello,

Each time i close the lid of the laptop, X reboots and i find my self
after opening on the loginscreen again.

i found the following:

dmesg: video bus notify

messages: gnome-power-manager: Using DPMS to power off display, as the lid
has been closed whilst been connected to a power supply (sorry for
traduction, its original in german)

Any idea?

Roger
