New Ubuntu 20.04

[MauryG5]

Power Community good morning, in April as we all know, both Ubuntu 20.04 and Fedora 32 will come out, COVID-19 emergency obviously allowing. About Ubuntu 20.04, I was asking myself a question or, what possibility will there be of using the AMD Radeon 5700 graphics cards that we currently use with Fedora with modified Kernel? I know I will use version 5.4 of the Kernel but I don't know what kind of support there will be for graphics cards, does anyone already know how it will work on Ubuntu?


Another thing that I did not understand is why they use 5.4 kernels when version 5.7 is already being developed and with 5.6 that if I have not misunderstood it is already working ...

Thank you

Who is "they"?

And for Ubuntu (as for any other POWER distribution): Navi support is broken.

[MauryG5]

They understood as the Ubuntu development team or Canonical. So are you telling me that you won't be able to use Navi 10 on Ubuntu? Not even doing a patched modified kernel?

[MPC7500]

Off course will a patched Kernel work, if you do the patch ... I'm talking about the stock Kernels. And Ubuntu used the 5.4 Kernel, because it was the up-to-date Kernel at that time, I guess.

[MauryG5]

So you think that the kernel with which Ubuntu 20.04 will come out does not have support for Navi10 / 14, but this is serious considering that these cards have been on the market for almost 1 year now ...

sorry guys, I read that among the novelties of the Ubuntu 20.04 kernel, there is support for the Navi 12 and 14 GPUs, therefore I also assume the Navi 10 which falls on that list. Is it possible therefore that by updating to 20.04 and inserting the modification of Xorg that we currently use on Fedora, you can directly activate our Navi 10 without any Patch? What do you know about it?

[MPC7500]

I hardly guess, you need the patch in any case. Furthermore 20.4 comes with Kernel 5.4, IIRC.

[MauryG5]

You mean that in our case as Power serves, because maybe only those who use the X86 version, can activate directly through the Xorg file, the Navi 10 or 14 graphics card...
