Title:
DisplayPort 1.2 MST support seems to be broken in the Intel driver
Status in “xserver-xorg-video-intel” package in Ubuntu:
Invalid
Bug description:
I have two recent DisplayPort monitors, both supporting the 1.2
version of the standard and one containing an MST hub (DELL 2913WM).
I have my laptop (Lenovo ThinkPad X230, HD4000 Ivy Bridge) connected
over mini-displayport to the display containing the hub, then the
second display is plugged in that one over DisplayPort.
DisplayPort 1.2 is enabled on the display containing the hub and the
second display lights up fine but just works as a clone of the first
display, without ever showing up in xrandr, dmesg or any other useful
logs I could find.
My understanding of MST is that the second display should show up as
DP2 on my laptop so I can configure it as I would any other display.
