Apr 11 20:30:49 netboy laptop-mode: Laptop mode 
Apr 11 20:30:49 netboy laptop-mode: enabled, 
Apr 11 20:30:49 netboy laptop-mode: not active [unchanged]
Apr 11 20:30:53 netboy kernel: [   75.450783] [drm:i9xx_crtc_mode_set] *ERROR* Couldn't find PLL settings for mode!
Apr 11 20:30:53 netboy laptop-mode: Laptop mode 
Apr 11 20:30:53 netboy laptop-mode: enabled, 
Apr 11 20:30:53 netboy laptop-mode: not active [unchanged]
