boot - 18.04 Freeze after login

After upgrading from 17.10 to 18.04 my system freezes after login, sometimes but not every time..




The system boots until I see the login screen, but after entering the password, I'm greeted with a black screen that does not go away. Ctrl+Alt+F1/2/3 does not do anything, the only way out is Alt+Sysrq+S/U/B.



1 - It seems that the boot goes fine when I see (previous to login) the big Ubuntu logo, while if I don't see it the login screen appears just the same but it will fail after login
2 - When I boot into recovery mode, do choose grub, then choose resume login, the boot works fine (without the big ubuntu logo)
3 - Tried with nNivia 396.24 and 390 drives with same result



I run a Threadripper with GTX 1080 Ti system. Xorg logs at <link>, but the best hint I could find in there is





[ 15.858] (EE) NVIDIA(GPU-0): Failed to acquire modesetting permission
[ 15.858] (EE) NVIDIA(0): Failing initialization of X screen 0




Thanks for any help!
