Update - linux-image-6.13.0_6.13.0-g87cc5488cf1b-39_riscv64.deb - Google Drive
final 6.13 + disabled atomic modesetting in amdgpu as it’s not working correctly anyway. now gdm/gnome on wayland can be used without MUTTER_DEBUG_FORCE_KMS_MODE=simple env var ( which was forcing non-atomic modesetting)

thank you so much @perunosx for this deb.

Starting from

jupi% lsb_release -a
No LSB modules are available.
Distributor ID:	Bianbu
Description:	Bianbu 2.1.1
Release:	2.1.1
Codename:	noble

With an m1.

I was able to use this, plus a hybrid of ubuntu 24.04 /bianbu to get full acceleration working with an Biostar Radeon RX 580 8GB Gaming 2048sp

Steps

  • Installed the kernel package
  • Removed bianbu-desktop
  • Switched /etc/apt/sources.list to official ubuntu 24.04 riscv ones
deb http://ports.ubuntu.com/ubuntu-ports noble main restricted universe multiverse
deb http://ports.ubuntu.com/ubuntu-ports noble-updates main restricted universe multiverse
deb http://ports.ubuntu.com/ubuntu-ports noble-backports main restricted universe multiverse
deb http://ports.ubuntu.com/ubuntu-ports noble-security main restricted universe multiverse
  • commended bianbu in /etc/apt/source.d/…
  • Removed the envs from /etc/envronment except the paths one
  • Force downgraded some pacakges via apt install package-name/noble
  • Installed ubuntu-dekstop-minimal (i had to downgrade a few packages in a loop til this worked)
  • added the user to the video group
  • installed linux-firmware

I got a full ubuntu 24.04 desktop, that works over hdmi + 4k, with no glitches. I’m soak testing now for stability with glmark2-wayland :).

update
soak test was stable for over 2 hours

glmark2 seems to be fully cpu limited at just 420 points ;|
