Public bug reported: Binary package hint: xorg
Occasionally the display will freeze, and a reboot is necessary. It always seems to happen when I do something graphical; by far most common is when I move between desktops using the pager or key combination, but it has happened once or twice at other times. I can log in using ssh, but killing X is impossible, necessitating a reboot. All system-related info is hopefully attached to this report. This is what I find with dmesg: [15447.042217] INFO: task i915:859 blocked for more than 120 seconds. [15447.042223] "echo 0 > /proc/sys/kernel/hung_task_timeout_secs" disables this message.
