I recently bought a new PC ThinkPad E580 with Intel and AMD graphics card.
I installed Ubuntu 19.04 in my PC as the dual system with Windows 10. Windows 10 works well but I had a great problem with the display in Ubuntu.
The first time when I went to install Ubuntu (even with "Try Ubuntu" on a live USB), the display would freeze, tear and jitter.

As suggested in Why do I need to replace "quiet splash" with "nomodeset"?, I added nomodeset in /etc/default/grub as:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nomodeset"
It temporarily resolved the problem, but leads to the audio codec module problem when the boost directly jump into the drive self test and block.
I updated the Intel driver, updated the kernel to 5.3, but no use. So does anyone have the same problem as me, and do you have any idea for that? The same problem occurs when I install Ubuntu 18 with exactly the same performance.
