I am running Ubuntu 14.04 on think-pad T450. When using an external monitor with higher resolution than the in-built laptop screen, the text of dialog boxes are getting messed up.
Looks like I need to replace the Graphic card driver. Anyone found a solution to this?
Updated to add requested information:
lspci -nnk | grep '\[03' -A2
gives the following:
00:02.0 VGA compatible controller : Intel Corporation Broadwell-U Integrated Graphics [8086:1616] (rev 09) Subsystem: Lenovo Device [17aa:5034] Kernel driver in use: i915
Below is a screenshot, see how the letters are messed up on the screen.
