I've had this problem, possibly in a slightly different manner, with F23/24 and KDE. My problem might be a bit different since I have a dongle connected to my Mini-DP port that splits to two HDMI outs since I have two large external monitors. I have a VGA port on mine, but that port doesn't support the 1900x1200 resolution these monitors have.
My problem is after a reboot, the Xorg config gets all jacked up I end up having to pull the mini-DP cable from the port, let the display reset to the laptop display, then re-connect the port. Most of the time that resets all the displays so I can use them. That may be more KDE related, but it's annoying as hell.

Hi!
I use a X1 Carbon 3rd gen and since the latest kernel update (maybe a week ago) the Mini DisplayPort does not work when connected at startup. Sometimes I can indeed connected my external monitor once I log in and it works, sometimes I have to boot with the previous kernel. I haven't troubleshooted much but was wondering if it was just me, or other were seeing the same behavior.
Thanks.

Hi!
Not sure whether my post made it to the list. Got a new kernel yesterday and same problem occurs. Any hint?
Thanks
Fred
