I have the same model »Asus ZenBook Pro 14 UX480« and the same issue. I was able to overcome to black screen and start the live mode with the following steps:
- Open Windows to allow disabling »Secure Boot« and browse to Settings > Update & Security > Advanced Startup options > Restart Now (will then open BIOS/UEFI automatically)
- In BIOS/UEFI disable »Secure Boot« & disable »Fast Boot«
- Save and exit
- Shut down, insert USB-Stick with bootable Ubuntu 19.04 (I tried Ubuntu 16.04, Ubuntu 18.04 and Mint 18.04 without any success)
- Hold F2 and press the power key to enter BIOS/UEFI
- Select the USB-Stick as Boot Option or Boot Override
- When the linux boot options appear select
Try Ubuntu without installing (safe graphics) using the arrow keys quickly and hit e to modify the start command
acpi=off (source) or use the options suggested by @ThankYee
- The live mode appears
To install Ubuntu then it is neccessary to:
- Switch from the pre-installed RAID drivers (Intel Rapid Storage Technology) to AHCI drivers BIOS - otherwise the live mode wont detect the SSD
I was not able to install Ubuntu alongside with Windows 10 - The installation always ended with an GRUB error. I was able to install Ubuntu as single OS however. I was able to install Ubuntu with LUKS/LVM encryption as well, but it required a manual update of GRUB after the installation using »boot repair«.
These problems still persist:
- The second screen underneath the touchpad is not working
- The touchpad is not working
- The buttons to adjust the screen brightness are not working
- Because of the
acpi=off hack the battery status is not available
- Because of the
acpi=off hack hibernation is not available
- It is not possible to install the Nvidia drivers - even with manual upgrades to the latest kernel
Today Ubuntu 19.10 was released and it works almost perfectly. 💜
To start the live mode, do everything above, but replace
quiet splash with
nomodeset (no need for the
acpi hack anymore).
The installation now works just fine. No Grub errors, no need for »boot repair« fixes with or without encryption. Ubuntu 19.10 even installs all needed Nvidia drivers automatically now.
The problems described above are gone, except for the second screen underneath the touchpad. The touchpad is working, brightness is working, battery icon, Nvidia drivers etc.
Two bugs reappear on a regular basis:
