Hi Luya,

The complete journal doesn't appear to be attached, so I don't know what kernel is actually being booted here, but I see there's something in the logs about a DKMS build for amdgpu against 4.18.14.

Can you reproduce this on a fresh install and attach the complete logs if so ("journalctl --no-hostname -b 0" should do it)?

journal boot report using kernel 4.19.0

That is strange. On livemedia, the boot looks fine but I am unable to pick the journal boot report on post installation. Possibly due to the migration of data from HDD to SSD.
I attempt to vainly use external HDD that used to be part on my laptop, HP Envy x360 Ryzen 2500u. Not sure why it failed.

Comment 3 Luya Tshimbalanga 2018-10-26 05:10:46 UTC
ACPI error in the kernel broke both touchscreen and stylus support as seen on https://bugzilla.kernel.org/show_bug.cgi?id=198715

It looks like the fresh install resolved the issue.

Closing this report as I noticed no further issue since fresh installation.
