Installation of NVDIA drivers on ASUS ZenBook 14 UX431FN-AN001T

I just installed ubuntu 18.04.3 LTS 64b on an ASUS ZenBook 14 UX431FN-AN001T using both Intel and NVIDIA GeForce MX150.

I don't manage to use the nvidia graphic card and up to now, could use the laptop only booting with nomodeset in resolution 800x600 and there is no possibility to adjust the screen resolution to 1920x1080.

I installed the nvidia drivers (version 430, as suggested by the command ubuntu-drivers devices) from the "software & updates"/"Additional Softwares" panel (dkms status indicates : nvidia, 430.26 installed), and restarted the computer (with secure mode disabled).

After the command "prime-select nvidia": Booting without nomodeset I only get a black screen, and rebooting with nomodeset it blocks on a black screen with only a white underscore sign at upper left corner.

When using instead "prime-select intel", the booting has been successful once with nomodeset, but now blocks on a black screen with only a white underscore sign (with no explaination), while i still get a black screen without nomodeset.

I tried previously the fedora distribution and encountered the same issues, i tried to install the most recent nvidia-435 driver (indicated on the nvidia website as the ultimate driver for geforce mx150) downloading it directly from the nvidia website and ended up always with the black screen. I don't know how to proceed any further, someone can help?

Some more indications:

I had a similar problem with Nvidia graphics card in ubuntu.

You can try this

1) Remove all the drivers of Nvidia with the help of purge check here how to remove all Nvidia drivers How can I uninstall a nvidia driver completely ?. Then reboot the pc, this will solve your problem.

2) If that doesn't solve your problem then backup all your important data from ubuntu and get ready to reinstall ubuntu, but this time while reinstalling don't tick the option install third-party software then complete the ubuntu installation as usual.

I finally solved the issue of the black screen, following instructions found there: https://ubuntuforums.org/showthread.php?t=2420705

The solution is the following:

It's a problem with edid version 2.4

Here is the workaround:

1. Download 1920x1080.bin from here

2. Move it to /lib/firmware/edid/

3. Edit /etc/default/grub and add this:

   GRUB_CMDLINE_LINUX_DEFAULT="drm.edid_firmware=eDP-1:edid/1920x1080.bin"
   

4. Run sudo update-grub

5. Restart the computer
