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!

Finally!

It seems that for now I've solved the problem by running (as user):

chmod 777 ~/.ICEauthority 
sudo dpkg --configure -a

Hope it helps somebody. To find this solution I used information found <here>.

Edit: maybe useful to add that I also changed grub, like this:

sudo nano /etc/default/grub

Change this line: GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

To this: GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nomodeset"

Save and exit, then run:

sudo update-grub
