I'm running an T450s with 2 external DELL monitors, one 24" and a DELL 27", both are connected by Displayport.

After locking the desktop by windows+L key and returning after some time (minutes) the 27" DELL isn't working anymore and i have to reconfigure the whole display settings, the dmesg output bring up the following lines:
…
