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
- Replace
quiet
with 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
Update 2019-09-29
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
Update 2019-10-17
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.
Update 2019-10-23
Two bugs reappear on a regular basis:
nomodeset
. This is all you need to run a live session (and install) with a generic video mode. Later you need to boot with the same parameter and install Nvidia drivers. This assumes the media you're booting is working fine.
