external monitor of a docked ThinkPad needs "chvt1; chvt7" after s2ram
otherwise the monitor is just black, although the docked ThinkPad T440s wakes up fine iand is up and running. (system: i5, i915, current kernel and older kernel versions of a 64 bit hardened Gentoo linux).
Just to help to improve the kernel (if it is a kernel issue).
