I updated to A04 and it did not make a difference.
$ sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date
A04
05/15/2015
Furthermore, I tried on 4.0 and 4.1 kernels (keeping the 15.04
userspace) and this also made no difference.
You asked to specify what happened with A04, it is the same as the
description: "I have a Dell XPS 13 9343 with external display link
monitor which I use in non-mirrored mode as two different screens. If
the screen locks and suspends (simply locking is not enough) if I tap a
key/move the mouse/etc the laptop screen comes up and the external
monitor flashes on, but then the external monitor goes blank (but I can
see its backlight is on). If I login, the desktop seems to think it is
off and all of open windows are rearranged (it even puts some on
different workspaces)."

all of open windows are rearranged (it even puts some on different
workspaces). The only thing resembling a workaround is if I tap a key,
watch when the external monitor is blank, then turn off the external
monitor, then turn it on, then unlock the screen. This isn't great
though-- some windows are invisible and rearranged and I have to cycle
through the different workspaces to find them and put them back.
