Public bug reported:
I have tried cables, drivers, upgrades --no matter what I do I cannot
get Ubuntu to recognize that my 32" UHD LG display supports 2560x1440. I
can work around it with `cvt` and `xrandr` but this is tedious and is
not saved across sessions, and xorg.conf is no longer a possibility
(bricks the system).
