Thinkpad R400: High CPU usage after opening lid
Hello,
Running Arch on a Thinkpad R400. Desktop environment is KDE, I have it configured to take no action upon laptop lid closing.
Upon opening the lid, I get the following lines in /var/log/Xorg.0.log. While these lines are being produced, the CPU is under very heavy load (specifically, the X process) and mouse movement becomes choppy. It seems to be repeatedly detecting the LCD panel. During this process the screen does not flicker or anything, and after it completes the system functions normally.
Edit: I'd just like to specify that this does not happen *while* the screen is off.
