How to install ubuntu 18.04 desktop on ASUS ROG Strix GL12cx

I’m trying to install Ubuntu18 on my PC[1].

The Ubuntu18.04 installation program cannot even login with nomodeset option. Therefore, I tried Ubuntu19.04.

I could login with “safe graphic” mode and install nvidia driver. But after the driver is installed, I cannot boot into system by nomodset.

What I had tried:
(1) Ubuntu18.04 Desktop => Install => nomodeset => black screen
(2) Ubuntu19.04 Desktop => Install => safe graphic => success to install => reboot => nomodeset on GRUB => success to boot (I can reboot to GUI with nomodeset if I do not touch any GPU driver) => Install Nvidia driver 440.64 => nvidia-smi success => reboot => nomodeset can never boot the PC.
(3) Ubuntu20.04 (daily build/ 2020.3.28) => Install => safe graphic => black screen

I’ve tried these options

Can you switch to a VT using CTRL+ALT+F1(orF2…F6) and login if you remove all mentioned kernel parameters?
Then please run as root and attach the resulting nvidia-bug-report.log.gz file to your post. You will have to rename the file ending to something else since the forum software doesn’t accept .gz files (nifty!).
If you have internet connection, you can use pastebinit to upload it from console.

  • install pastebinit (sudo apt install pastebinit)
  • unzip logfile (gunzip nvidia-bug-report.log.gz)
  • upload logfile (pastebinit -i nvidia-bug-report.log)
  • note down and post the url you’re given
