Every time this happens using driver intel on xorg.conf the /var/log/Xorg.0.log shows:
(II) PM Event received: Capability Changed
I830PMEvent: Capability change
when I change to i810:
(II) PM Event received: Capability Changed
I830PMEvent: Capability change
(II) I810(0): Next ACPI _DGS [0] 0x80000410
(II) I810(0): ACPI Toggle devices 0x800
(II) I810(0): ACPI Toggle to 0x800
A lspci, Xorg.0.log and /proc/mtrr is attached I can submit more information if you need.
Using (or not) the latest patch (http:// www2.eng. cam.ac. uk/~pcjc2/ ubuntu/ xserver- xorg-video- intel_2. 1.1-0ubuntu10~ pcjc2_i386. deb) I get a blank screen on Kubuntu Gusty when I close the lid of my laptop Compaq nx6120 with a i810. It does not lock the computer, just makes the screen goes black after a few seconds and totally random (with or without user interaction).
