Unable to use encrypted account and DE (possible graphical issues)

First, I’m not able to load Ubuntu normally. I will get black screen without any action and monitor will turn off.

I have to use recovery mode, then to escape graphical loader (F8), then resume load.

With these steps I’m able to access login screen.

I’m able to enter wrong password and get an error message, but when I enter correct password I get black screen and then I’m presented with login screen again.

I tried recovery option, every kernel version, every DE variant (I have 3 of them) but none of them work (without extra commands).

My network is functional in guest account, but not video card (driver is enabled but doesn’t work really)

I want to restore access or all info from my encrypted account.
