[Bug 1492494] Re: When changing to Ultra HD screen flickers
Kai Mast, 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-t440s an update to your
computer's buggy and outdated BIOS is available (2.34). 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:
When changing to Ultra HD screen flickers
Status in xserver-xorg-video-intel package in Ubuntu:
Incomplete
Bug description:
After changing from a lower resolution to 4k bottom left of the screen
looks fine everything else flickers. When I restart X11 the whole
screen looks perfect.
Seems like a problem with mode setting and/or MST?
I am using a lenovo thinkpad T440s with a dockingstation (but also
seems to happen when not connection through the docking station).
