[SOLVED] No GUI at all after GPU upgrade

Post by ruby_R53 » Mon Jul 07, 2025 3:47 pm

I just upgraded from an AMD Radeon RX 550 to an RX 580 2048SP and now I can't get SDDM to show up.

I'm using a module-less Zen Kernel setup but have also tried enabling modules back and leave the driver loading job for the initramfs, but no luck with that. I've even double-checked the wiki for all the needed firmware blobs, and got the exact same result.

What I noticed is that when Gentoo finishes booting and tries to start SDDM, it fails. However, I can still see SDDM processes on htop. If I kill those and try to manually start SDDM, I get:

Code: Select all

Detected locale "C" with character encoding "ANSI_X3.4-1968", which is not UTF-8.
Qt depends on a UTF-8 locale, and has switched to "C.UTF-8" instead.
If this causes problems, reconfigure your locale. See the locale(1) manual
for more information.

I then tried to further investigate this by also manually starting X alone, and got this. What the heck is going on :?

And here is my emerge --info, also:

To me this looks like X11 doesn't load amdgpu driver at all. It's quite a long time since I've tinkered with X11... but:
  • check you have x11-drivers/xf86-video-amdgpu installed.
  • if you have some handwritten xorg.conf check that everything there is ok

i do have x86-video-amdgpu, but no xorg.conf files, so stuff should have been working

and well as i write this i just discovered that for whatever reason my kernel didn't load the amdgpu driver after booting, so now i manually did that and everything's up now!
i wonder why that happened tho'··· isn't it supposed to load all the necessary modules at boot or something

You wrote you have a module-less kernel; this means amdgpu is built-in <*> your kernel ... this means you have all firmware files for amdgpu in CONFIG_EXTRA_FIRMWARE ... are you sure you have all the correct for the NEW card?

You could check it with booting our LiveCD (not the minimal or admin) ... and then look at:

Code: Select all

dmesg | grep Loading
(this gives you all loaded firmware files)
[...] so now i manually did that and everything's up now!
This is a sign for missing firmware files; you surely already know that a static (built-in) module will be initialised BEFORE kernel hat access to its root partition (this is the reason for EXTRA_FIRMWARE) ... but all <M>odules will be initialised AFTER kernel has root access ... and therefore such modules are able to load their firmware files from /lib/firmware ... ;-)


P.S.: maybe read also viewtopic-p-8864850.html#8864850 ... maybe there are some problems with some version of linux-firmware

yeah, as i also mentioned in the first post i double-checked the Wiki for that

i see, will try that later on

interesting, kinda weird 'cos i didn't get any errors at all when i built the firmware files into my kernel nor when i installed linux-firmware

turns out you were right, i actually missed one single firmware blob to build into my kernel, now i'm back with my module-less setup xD
guess it's all solved now
