Lenovo T420 with FreeBSD 11 release, xfce and slim system showing problem that may be same as in thread 57449. New to FreeBSD so I can't be sure but the problem didn't appear until upgraded from 10.3. Sporadically, on power up the screen is offset up with the lower quarter of screen black and at a 1024x768 resolution (checked in Settings Display). Editing the settings in Setting manager has no effect, but on shutting down or rebooting a few times the correct display position and resolution (1366X768) returns. Following suggestion in cited thread: Output from xrandr with no args when display is bad:
