[Problem]

When the laptop lid is closed, the GPU hangs at MI_WAIT_FOR_EVENT Display Pipe B Scan Line Window Wait Enable (0x01800020). Logs and i915_error_state from drm-intel-next kernel before close, after close, and after open are attached.

[Original report]

Binary package hint: xserver-xorg-video-intel

When I close the laptop lid (I have set it to blank the screen, NOT SUSPEND) and open it, the screen remains black for a while, the xorg is killed and gdm restarts.

If quickly switching to the VT, Xorg does not crash.
If gnome-settings-daemon is not running, this bug does not exist.
