I have a prime setup. I used mhwd and now the System wont even boot. 
I'm not sure if I should reinstall or try to fix using chroot. Terrible Update so far.
It cant find my card. I have a Nvidia prime setup with an Intel discrete card this might be Part of the problem. Im open to sugestions as this install is 2 years old and with some important customizations.
So it seemed to be a problem with mhwd doing something incorrectly while installing the the driver.
What i did now is changing the xorg config to use nouveu driver, restarting the system and than uninstalling and installing the nvidia driver 440xx. With the next boot everything just worked Oo
Can you provide a link for it? I could not fix my System so far.
It seems you have installed nvidia-440 driver. If you have kernel 4.19, try booting that one. Else, install it, as it's currently the best option for the nvidia issues.
More info is needed, in order to give a better answer, sorry...

Xorg log
I feel you are currently unsure about what is being suggested and you ignored the fact I have a prime setup which might differ in how to be handled.
I have the same problem, 430xx doesnt work because of the update and 435x and 440x yield a blackscreen with the cursor. I got a 1050ti
Not to my knowledge... 
. Thanks for you boosting my self-confidence!!
My 1st approach had to be to exclude the common issues introduced with the latest Stable Update.
I suggest you start a new topic to handle your Prime setup better.
A best guessed temp workaround would be to rename/disable your xorg conf file, so you get GUI on Intel (from TTY). Maybe your sddm Xsetup script needs to be disabled as well (if needed).

Try nvidia 440 or 418 with kernel 4.19.
Also try the fallback kernel images at boot (hopefully helpful...).
I tried the 440 with the same blackscreen as the user above, and I am on kernel 4.19 already./
I did try 4.14 and the fallback kernel images but none of them work.
