I found this few months old discussion[1] on freebsd-acpi (related to Thinkpad X201): "I had a similar problem. After syncing with FreeBSD 10-CURRENT and compiling a kernel without VESA support, I was able to get graphics to work on resume, but only when running X. " This works for the X121e too! It is now able to suspend and resume properly when running Xorg (with i915kms.ko). I'm really happy :-) There is only a (very minor) problem: after the first resume Xorg graphics seem to slow down. When moving windows on the screen they leave some traces behind and it takes some milliseconds until they are wiped away and replaced with the background image. Kind regards, Matthias [1] http://freebsd.1045724.n5.nabble.com/Resume-failed-after-Suspend-on-Thinkpad-x201i-td5723622.html
