The strange behaviour here is that you reported it does not happen if only the home partition is encrypted: if this is true this could not be a GPU issue.

AFAIU ThinkPad T430 could come with an additional "NVIDIA NVS 5400M" GPU [1] that is very Linux _unfriendly_; you can check this by booting your machine as detailed below and doing a "lspci -nnn | grep VGA" Anyway, to check if GPU is the problem here could you please add "modprobe.blacklist=3Dradeon" [2] (or vga=3D791 if this does not work [3]) to the "linux" kernel arguments and report back the error messages, if any? To add that kernel argument, you have to enter edit mode in Grub by pressing "e" before the timeout (or press ESC to stop the timeout) and edit the "linux" Grub line If blacklisting radeon module works for you, you should add it to your (operating-system ...) definition to make it permanent, something like: (kernel-arguments '("modprobe.blacklist=3Dradeon")) HTH! Gio'.
