nickolai, thank you for reporting this and helping make Ubuntu better.
As per http://support.lenovo.com/us/en/products/laptops-and-
netbooks/thinkpad-t-series-laptops/thinkpad-t520 an update to your
computer's buggy and outdated BIOS is available (1.45). If you update to
this following https://help.ubuntu.com/community/BIOSUpdate does it
change anything?

If it doesn't, could you please both specify what happened, and provide the output of the following terminal command:
sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date

For more on BIOS updates and linux, please see
https://help.ubuntu.com/community/ReportingBugs#Bug_reporting_etiquette
.

Please note your current BIOS is already in the Bug Description, so
posting this on the old BIOS would not be helpful. As well, you don't
have to create a new bug report.

Once the BIOS is updated, if the problem is still reproducible, and the
information above is provided, then please mark this report Status New.
Otherwise, please mark this as Invalid.

Thank you for your understanding.

Title:
  Thinkpad T520 / i915 blank X display in 15.04

Status in xserver-xorg-video-intel package in Ubuntu:
  Incomplete

Bug description:
  After upgrading my Thinkpad T520 laptop to Ubuntu 15.04, the X server
  gives a blank black screen (but backlight is still on).  I can switch
  to other virtual consoles (ctrl-alt-F1, etc) and log in, so the rest
  of the system is running just fine.  The blank screen shows up
  regardless of how X is started -- via lightdm, using startx, or even
  running X explicitly.
