ThinkPad Ultra Dock 90W (40A20090XX) display issues

I am using my Thinkpad T440s with ThinkPad Ultra Dock 90W (40A20090XX). I have two external monitors connected over display port. Every time I dock my laptop I am unable to use the external monitors when I use xrandr. I get xrand crtc 1 failed error. I have to reboot my laptop for the displays to work. I was wondering if any one knows how I can solve this issue.
