I would like to get your help to collect some debug log for our analysis further. Please enabled drm debug in kernel message, and collect kennel command/i915 parameter/xrandr's output. Then reproduce this this issue (dock/undock) and sharing them with kernel message with us. Thanks! 1. drm debug-enabled log, echo 0xe > /sys/module/drm/parameters/debug 2. get kernel command cat /proc/cmdline 3 get i915 parameters cat /sys/kernel/debug/dri/0/i915_display_info tail -n +1 /sys/module/i915/parameters/* cat /sys/kernel/debug/dri/0/i915_capabilities 4. get X's information. xrandr -q</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> <li>You are the QA Contact for the bug.</li> <li>You are on the CC list for the bug.</li> </ul> </body> </html>
