Is it possible, > considering that this gpu has free software drivers? I proposed removing quiet so more messages would get printed to the screen, but your photo already shows everything. So this is bad news. Technically the amdgpu drivers themselves are free software, but they require nonfree firmware, and linux-libre removes it. With linux-libre, there is therefore no way to use the GPU for 3D acceleration, I believe. In your original post, you said you succeeded in installing Guix System with the installer image. The installer image uses uvesafb-service-type when amdgpu fails, so you could do the same. See the installer’s configuration file at: ~/.config/guix/current/share/guile/site/3.0/gnu/system/install.scm The workaround I suggested at On Tue, Apr 19, 2022 at 10:50:47AM +0200, pelzflorian (Florian Pelz) wrote: > (If it AMD turns out to be the issue, Denis 'GNUtoo' Carikli suggested > to partially fix them , while I > suggested to work around them . > Manjaro would not have these issues because it uses a nonfree linux > package. But your bug may be something completely different.) is a more concise way to unconditionally load uvesafb, even for graphical desktops. Denis’ suggestion to fix the driver is a more proper solution but more work, if it works. Either way you won’t be able to use accelerated 3D with linux-libre. I’m merging this bug with 48343.
