ASUS Vivobook TP420IA boots to black screen

Hello all,

I’m a novice Linux user and wanted to switch to Manjaro for my new notebook. I bought a ASUS Vivobook TP420IA Convertible, because it suits my specs: Ryzen 4700U, 16GB Ram, 500GB SSD.
Booting from USB works fine and after some tests, I decided to install. I used Manjaro 20.1 XFCE. And at first, it worked fine, but a few reboots, now it always stops at a black screen.

I found another thread with a similar problem, but a HP 445 G7, but at least It got some Idea (/t/impossible-installation-on-hp-455-g7-amd-renoir-4500u/26755/12).

I can go to the console by pressing CRTL+ALT+F2, update everything and was able to upload these logfiles with the commands stated in the previous thread:
journalctl -b -0 | curl --upload-file - aptget xyz/boot.0.log: aptget xyz/YzFVt/boot.0.log
inxi -Fazy | curl --upload-file - aptget xyz/inxi.log: aptget xyz/AbH39/inxi.log

(removed https and inserted some spaces in there because apprently, as a new user, I’m not allowed to post links)

startx doesn’t work and just goes back to the console. I’mt not experience enough to get useful information from the log. The BIOS isn’t extensive, but I deactivated Secure Boot and Fast Boot, there is not much else I can do.

I hope someone here can make something of the log or has another idea, what goes wrong. Thanks in advance for any help!

Hello :wave:

So the question would be: What have been changed?

I see some problems with ACPI:

That should be solved first. Have look here:

The ACPI issue could be solved with an UEFI upgrade:

Okt 13 00:07:22 skr-ultrabook-lnx64 kernel: DMI: ASUSTeK COMPUTER INC. VivoBook_ASUSLaptop TP420IA_TM420IA/TP420IA, BIOS TP420IA.209 06/05/2020

Latest Version: 2020/07/06
Your Version: 2020/05/06

Maybe try also to completely disable the legacy BIOS mode, so run it in full UEFI mode.

Have also look at:

An update:

The UEFI Update was released while I posted the thread, so I missed it. But its updated now, but didn’t change anything.
Also I tried multiple combinations of acpi_osi=, but none did a improve it. I noticed that sometimes it boots properly, but ~9/10 times, it doesn’t.

Updated logs:
aptget.xyz/y6mkH/boot.0.log
aptget.xyz/y22zQ/inxi.log

Still working on the other linked threads.
