[fedora-arm] Re: Help getting Fedora working on my rpi3

Thanks, I see the xfce spin for aarch64 now, I was looking in the wrong place before. I'm trying it now, and it was able to boot into xfce successfully without having to add the 'cma=192M' karg mentioned in the wiki... is that still necessary/recommended? And if so, is 'grubby --args="cma=192M" --update-kernel=ALL' the correct way to do that?

First off, for this hardware, should I be using the aarch64 or armhfp images? I've been trying with aarch64 and that boots, but just wanted to doublecheck. Second, is it possible to get Gnome running? The "hardware status" wiki page says XFce is recommended, but it's not clear whether that means Gnome won't work, or if it's just not recommended. I tried the Workstation image and the firstboot wizard runs successfully, but then when attempting to login, gnome-shell crashes after chugging for a couple minutes and dumps me back at the gdm login screen. I tried adding 'cma=192M' to kernel args as suggested on the wiki, but no change.

You should use aarch64, we're retiring armhfp post F-36. The problem
with GNOME is that you need to allocate 256Mb of RAM for the GPU for
it to work and then remaining ~768Mb doesn't give you a lot of space
to run an OS and app. Given those constraints it works to some
definition of "work".

> If the answer turns out to be the Gnome isn't going to work and I have to go with Xfce, I don't see an Xfce spin built for aarch64, only armhfp, is that correct? Is that what I should be using?

There is XFCE for aarch64.
