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:
