I don't know why Manjaro 18 (Gnome) works for me?maybe I got lucky ;-); clean install, no damn boot args, everything works( brightness keys, trackpad on advanced, etc), power management works like a charm.
At first, I had a WiFi bug, which was fixed when I updated Manjaro using ethernet connection. My laptop is Acer Aspire A315-41(Ryzen 5 2500u).Also, there will be no WiFi issues if you can use KDE version, but just find it very buggy and slow, so kept using Gnome -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1776563 Title: Acer Aspire A315 IOAPIC failure on Ubuntu 18.04, kernel hangs, can't load, kernel freeze (AMD Ryzen 5/Radeon/Raven) / AMDGPU Hybrid crash To manage notifications about this bug go to: https://bugs.launchpad.net/amd/+bug/1776563/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
