** Description changed: Binary package hint: xserver-xorg-video-intel This is a brand new Acer AS1410 laptop, running i386 Ubuntu Karmic, Netbook Remix. The graphics adapter is Intel X4500MHD (8086:2a42 PCI ID), supported by the i915 kernel driver. Yesterday, I tried closing the screen lid to save power while listening to music. The music began to stutter when I did this, and the fan came on. After I opened the lid again, several windows continued to flicker for 10-20 seconds, and running top showed that the Xorg server was consumed 80-100% of the CPU cycles. Inspecting the /var/log/messages, I find the following error repeatedly rapidly when the screen is closed: Oct 10 01:59:56 dlenski-laptop kernel: [ 1292.698045] i915 0000:00:02.0: DVI-D-2: no EDID data Oct 10 02:00:20 dlenski-laptop kernel: [ 1336.707144] i2c-adapter i2c-2: unable to read EDID block.

Oct 10 02:00:20 dlenski-laptop kernel: [ 1336.721316] i915 0000:00:02.0: DVI-D-2: no EDID data Apparently, the i915 driver fails to acquire information about the LCD panel when the lid is closed??? Disabling the screen by some other mechanism, such as running "xset dpms force off", does not seem to cause this problem. This bug is similar to, but not identical to, https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video- intel/+bug/156824, which also involves problems that appear after closing the lid on a laptop with the i915 graphics driver.
