It is not possible to use antergos with nvidia proprietary drivers + luks encryption + KDE

[Lemminsky]

Like in title. It's a pretty big issue. Installing antergos kde with luks encryption and proprietary nvidia drivers renders the system unusable. System stalls after typing in luks password. This is not the case with open source drivers, kde and luks nor is it the case with proprietary drivers, luks and openbox.

For the reference: I use a thinkpad w530, stock bios, stock Intel 160 GB SSD, nvidia quadro k1000
