no screen output prior to login while in docking station

[kringalf]

while the laptop is in the docking station there is no output on any monitor as long as i'm not logged into kde.
The output stops right after the password for the encrypted root disk and the screens stay blank until i login to kde
if i start outside the docking station i get output on the screen through the whole boot process including the login process for kde

Hardware is a DELL LATITUDE E6530

Can be closed. I had to reinstall and the problem doesn't exist any more

Thank you for taking the time to report this bug and helping to make Ubuntu better. We are sorry that we do not always have the capacity to review all reported bugs in a timely manner.

kringalf, thank you for comment #3. I'm sorry that it took nearly six years long for anyone to see that you had resolved the issue. I'm closing this as "Invalid" as Ubuntu 16.04 is no longer being maintained and the issue wasn't resolved by an Ubuntu update.
