[XORG] Black screen xorg error

[ilgios]

Hi there,
i'am so sorry to disturb you, but i really don't know what to do. I am new on linux world, so please be patience with me, i'ma so sorry.

I have installed on my laptop ASUS N552V kubuntu 18.04 and everything was working perceftly till then I rebooted it . After the reboot i got X not working and tty cursor ready. So i entered credentials, and when i checked /var/log/Xorg.0.log i found this error:

EE Segmentation fault at address 0x50

Fatal server error

I did dist-update, autoremo, apt-get update, upgrade but nothing helped me.
I have reinstalled nvidia video drivers to 396 version.

Could someone help me, please?

Thanks

What is your NVidia chip model number?
How did you install the 396 driver.

What worked for me was simply openining a Konsole and issuing
sudo ubuntu-drivers autoinstall

For your situation I'd purge the 396 and auxiliary programs, reboot, and then issue the command above.
