Hi, I'm experiencing strange bug when I close lid of my Dell Studio 1555 - system is totally frozen (no answers form ssh, no key reaction) and display is showing some blurring, moving, colourful rectangles (see photos [1] [2]). Any suggestions what causes it or how to debug it (kernel log shows nothing)?
